# AWS Serverless
|
||||
|
||||
## Patterns
|
||||
|
||||
### Lambda Handler Pattern
|
||||
|
||||
Proper Lambda function structure with error handling
|
||||
|
||||
**When to use**: ['Any Lambda function implementation', 'API handlers, event processors, scheduled tasks']
|
||||
|
||||
```python
|
||||
```javascript
|
||||
// Node.js Lambda Handler
|
||||
// handler.js
|
||||
|
||||
// Initialize outside handler (reused across invocations)
|
||||
const { DynamoDBClient } = require('@aws-sdk/client-dynamodb');
|
||||
const { DynamoDBDocumentClient, GetCommand } = require('@aws-sdk/lib-dynamodb');
|
||||
|
||||
const client = new DynamoDBClient({});
|
||||
const docClient = DynamoDBDocumentClient.from(client);
|
||||
|
||||
// Handler function
|
||||
exports.handler = async (event, context) => {
|
||||
// Optional: Don't wait for event loop to clear (Node.js)
|
||||
context.callbackWaitsForEmptyEventLoop = false;
|
||||
|
||||
try {
|
||||
// Parse input based on event source
|
||||
const body = typeof event.body === 'string'
|
||||
? JSON.parse(event.body)
|
||||
: event.body;
|
||||
|
||||
// Business logic
|
||||
const result = await processRequest(body);
|
||||
|
||||
// Return API Gateway compatible response
|
||||
return {
|
||||
statusCode: 200,
|
||||
headers: {
|
||||
'Content-Type': 'application/json',
|
||||
'Access-Control-Allow-Origin': '*'
|
||||
},
|
||||
body: JSON.stringify(result)
|
||||
};
|
||||
} catch (error) {
|
||||
console.error('Error:', JSON.stringify({
|
||||
error: error.message,
|
||||
stack: error.stack,
|
||||
requestId: context.awsRequestId
|
||||
}));
|
||||
|
||||
return {
|
||||
statusCode: error.statusCode || 500,
|
||||
headers: { 'Content-Type': 'application/json' },
|
||||
body: JSON.stringify({
|
||||
error: error.message || 'Internal server error'
|
||||
})
|
||||
};
|
||||
}
|
||||
};
|
||||
|
||||
async function processRequest(data) {
|
||||
// Your business logic here
|
||||
const result = await docClient.send(new GetCommand({
|
||||
TableName: process.env.TABLE_NAME,
|
||||
Key: { id: data.id }
|
||||
}));
|
||||
return result.Item;
|
||||
}
|
||||
```
|
||||
|
||||
```python
|
||||
# Python Lambda Handler
|
||||
# handler.py
|
||||
|
||||
import json
|
||||
import os
|
||||
import logging
|
||||
import boto3
|
||||
from botocore.exceptions import ClientError
|
||||
|
||||
# Initialize outside handler (reused across invocations)
|
||||
logger = logging.getLogger()
|
||||
logger.setLevel(logging.INFO)
|
||||
|
||||
dynamodb = boto3.resource('dynamodb')
|
||||
table = dynamodb.Table(os.environ['TABLE_NAME'])
|
||||
|
||||
def handler(event, context):
|
||||
try:
|
||||
# Parse i
|
||||
```
|
||||
|
||||
### API Gateway Integration Pattern
|
||||
|
||||
REST API and HTTP API integration with Lambda
|
||||
|
||||
**When to use**: ['Building REST APIs backed by Lambda', 'Need HTTP endpoints for functions']
|
||||
|
||||
```javascript
|
||||
```yaml
|
||||
# template.yaml (SAM)
|
||||

const { getItem } = require('../lib/dynamodb');
|

exports.handler = async (event) => {
|
||||
const id = event.pathParameters?.id;
|
||||
|
||||
if (!id) {
|
||||
return {
|
||||
statusCode: 400,
|
||||
body: JSON.stringify({ error: 'Missing id parameter' })
|
||||
};
|
||||
}
|
||||
|
||||
const item =
|
||||
```
|
||||
|
||||
### Event-Driven SQS Pattern
|
||||
|
||||
Lambda triggered by SQS for reliable async processing
|
||||
|
||||
**When to use**: ['Decoupled, asynchronous processing', 'Need retry logic and DLQ', 'Processing messages in batches']
|
||||
|
||||
```python
|
||||
```yaml
|
||||
# template.yaml
|
||||
Resources:
|
||||
ProcessorFunction:
|
||||
Type: AWS::Serverless::Function
|
||||
Properties:
|
||||

|
||||

|
||||

|
||||
FunctionResponseTypes:
|
||||

|
||||
|
||||
ProcessingQueue:
|
||||
Type: AWS::SQS::Queue
|
||||
Properties:
|
||||
VisibilityTimeout: 180 # 6x Lambda timeout
|
||||
RedrivePolicy:
|
||||
deadLetterTargetArn: !GetAtt DeadLetterQueue.Arn
|
||||
maxReceiveCount: 3
|
||||
|
||||
DeadLetterQueue:
|
||||
Type: AWS::SQS::Queue
|
||||
Properties:
|
||||
MessageRetentionPeriod: 1209600 # 14 days
|
||||
```
|
||||
|
||||
```javascript
|
||||
// src/handlers/processor.js
|
||||
exports.handler = async (event) => {
|
||||
const batchItemFailures = [];
|
||||
|
||||
for (const record of event.Records) {
|
||||
try {
|
||||
const body = JSON.parse(record.body);
|
||||
await processMessage(body);
|
||||
} catch (error) {
|
||||
console.error(`Failed to process message ${record.messageId}:`, error);
|
||||
// Report this item as failed (will be retried)
|
||||
batchItemFailures.push({
|
||||
itemIdentifier: record.messageId
|
||||
});
|
||||
}
|
||||
}
|
||||
|
||||
// Return failed items for retry
|
||||
return { batchItemFailures };
|
||||
};
|
||||
|
||||
async function processMessage(message) {
|
||||
// Your processing logic
|
||||
console.log('Processing:', message);
|
||||
|
||||
// Simulate work
|
||||
await saveToDatabase(message);
|
||||
}
|
||||
```
|
||||
|
||||
```python
|
||||
# Python version
|
||||
import json
|
||||
import logging
|
||||
|
||||
logger = logging.getLogger()
|
||||
|
||||
def handler(event, context):
|
||||
batch_item_failures = []
|
||||
|
||||
for record in event['Records']:
|
||||
try:
|
||||
body = json.loads(record['body'])
|
||||
process_message(body)
|
||||
except Exception as e:
|
||||
logger.error(f"Failed to process {record['messageId']}: {e}")
|
||||
batch_item_failures.append({
|
||||
'itemIdentifier': record['messageId']
|
||||
})
|
||||
|
||||
return {'batchItemFailures': batch_ite
|
||||
```
|
||||
|
||||
## Anti-Patterns
|
||||
|
||||
### ❌ Monolithic Lambda
|
||||
|
||||
**Why bad**: Large deployment packages cause slow cold starts.
|
||||
Hard to scale individual operations.
|
||||
Updates affect entire system.
|
||||
|
||||
### ❌ Large Dependencies
|
||||
|
||||
**Why bad**: Increases deployment package size.
|
||||
Slows down cold starts significantly.
|
||||
Most of SDK/library may be unused.
|
||||
|
||||
### ❌ Synchronous Calls in VPC
|
||||
|
||||
**Why bad**: VPC-attached Lambdas have ENI setup overhead.
|
||||
Blocking DNS lookups or connections worsen cold starts.
|
||||
|
||||
## ⚠️ Sharp Edges
|
||||
|
||||
| Issue | Severity | Solution |
|
||||
|-------|----------|----------|
|
||||
| Issue | high | ## Measure your INIT phase |
|
||||
| Issue | high | ## Set appropriate timeout |
|
||||
| Issue | high | ## Increase memory allocation |
|
||||
| Issue | medium | ## Verify VPC configuration |
|
||||
| Issue | medium | ## Tell Lambda not to wait for event loop |
|
||||
| Issue | medium | ## For large file uploads |
|
||||
| Issue | high | ## Use different buckets/prefixes |
|
||||
|
||||

||||
|
||||
> Essential patterns for Bash on Linux/macOS.
|
||||
|
||||
---
|
||||
|
||||

|
||||
---
|
||||
|
||||
## 3. Process Management

|
||||
| Jobs | `jobs -l` |
|
||||
| Bring to front | `fg %1` |
|
||||
|
||||
---
|
||||
|
||||
## 4. Text Processing
|
||||
|
||||
### Core Tools
|
||||
|
||||
| Tool | Purpose | Example |
|
||||
|------|---------|---------|
|
||||
| `grep` | Search | `grep -rn "TODO" src/` |
|
||||
| `sed` | Replace | `sed -i 's/old/new/g' file.txt` |
|
||||
| `awk` | Extract columns | `awk '{print $1}' file.txt` |
|
||||
| `cut` | Cut fields | `cut -d',' -f1 data.csv` |
|
||||
| `sort` | Sort lines | `sort -u file.txt` |
|
||||
| `uniq` | Unique lines | `sort file.txt \| uniq -c` |
|
||||
| `wc` | Count | `wc -l file.txt` |
|
||||
|
||||
---
|
||||
|
||||
## 5. Environment Variables
|
||||
|
||||
| Task | Command |
|
||||
|------|---------|
|
||||
| View all | `env` or `printenv` |
|
||||
| View one | `echo $PATH` |
|
||||
| Set temporary | `export VAR="value"` |
|
||||
| Set in script | `VAR="value" command` |
|
||||
| Add to PATH | `export PATH="$PATH:/new/path"` |
|
||||
|
||||
---
|
||||
|
||||
## 6. Network
|
||||
|
||||
| Task | Command |
|
||||
|------|---------|
|
||||
| Download | `curl -O https://example.com/file` |
|
||||
| API request | `curl -X GET https://api.example.com` |
|
||||
| POST JSON | `curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' URL` |
|
||||
| Check port | `nc -zv localhost 3000` |
|
||||
| Network info | `ifconfig` or `ip addr` |
|
||||
|
||||
---
|
||||
|
||||
## 7. Script Template
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -euo pipefail # Exit on error, undefined var, pipe fail
|
||||
|
||||
# Colors (optional)
|
||||
RED='\033[0;31m'
|
||||
GREEN='\033[0;32m'
|
||||
NC='\033[0m'
|
||||
|
||||
# Script directory
|
||||
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
|
||||
|
||||
# Functions
|
||||
log_info() { echo -e "${GREEN}[INFO]${NC} $1"; }
|
||||
log_error() { echo -e "${RED}[ERROR]${NC} $1" >&2; }
|
||||
|
||||
# Main
|
||||
main() {
|
||||
log_info "Starting..."
|
||||
# Your logic here
|
||||
log_info "Done!"
|
||||
}
|
||||
|
||||
main "$@"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 8. Common Patterns
|
||||
|
||||
### Check if command exists
|
||||
|
||||
```bash
|
||||
if command -v node &> /dev/null; then
|
||||
echo "Node is installed"
|
||||
fi
|
||||
```
|
||||
|
||||
### Default variable value
|
||||
|
||||
```bash
|
||||
NAME=${1:-"default_value"}
|
||||
```
|
||||
|
||||
### Read file line by line
|
||||
|
||||
```bash
|
||||
while IFS= read -r line; do
|
||||
echo "$line"
|
||||
done < file.txt
|
||||
```
|
||||
|
||||
### Loop over files
|
||||
|
||||
```bash
|
||||
for file in *.js; do
|
||||
echo "Processing $file"
|
||||
done
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 9. Differences from PowerShell
|
||||
|
||||
| Task | PowerShell | Bash |
|
||||
|------|------------|------|
|
||||
| List files | `Get-ChildItem` | `ls -la` |
|
||||
| Find files | `Get-ChildItem -Recurse` | `find . -type f` |
|
||||
| Environment | `$env:VAR` | `$VAR` |
|
||||
| String concat | `"$a$b"` | `"$a$b"` (same) |
|
||||
| Null check | `if ($x)` | `if [ -n "$x" ]` |
|
||||
| Pipeline | Object-based | Text-based |
|
||||
|
||||
---
|
||||
|
||||
## 10. Error Handling
|
||||
|
||||
### Set options
|
||||
|
||||
```bash
|
||||
set -e # Exit on error
|
||||
set -u # Exit on undefined variable
|
||||
set -o pipefail # Exit on pipe failure
|
||||
set -x # Debug: print commands
|
||||
```
|
||||
|
||||
### Trap for cleanup
|
||||
|
||||
```bash
|
||||
cleanup() {
|
||||
echo "Cleaning up..."
|
||||
rm -f /tmp/tempfile
|
||||
}
|
||||
trap cleanup EXIT
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
> **Remember:** Bash is text-based. Use `&&` for success chains, `set -e` for safety, and quote your variables!

## ⚠️ How to Use This Skill
|
||||
|
||||
This skill teaches **deployment principles**, not bash scripts to copy.
|
||||
|
||||
- Every deployment is unique
|
||||
- Understand the WHY behind each step
|
||||
- Adapt procedures to your platform
|
||||
|
||||

|
||||
|
||||
## 1. Platform Selection
|
||||
|
||||
### Decision Tree
|
||||
|
||||
```
|
||||
What are you deploying?
|
||||
│
|
||||
├── Static site / JAMstack
|
||||
│ └── Vercel, Netlify, Cloudflare Pages
|
||||
│
|
||||
├── Simple web app
|
||||
│ ├── Managed → Railway, Render, Fly.io
|
||||
│ └── Control → VPS + PM2/Docker
|
||||
│
|
||||

|
||||
|
||||
### Each Platform Has Different Procedures
|
||||
|
||||
| Platform | Deployment Method |
|
||||
|----------|------------------|
|
||||
| **Vercel/Netlify** | Git push, auto-deploy |
|
||||
| **Railway/Render** | Git push or CLI |
|
||||
| **VPS + PM2** | SSH + manual steps |
|
||||
| **Docker** | Image push + orchestration |
|
||||
| **Kubernetes** | kubectl apply |
|
||||

|
||||
## 2. Pre-Deployment Principles
|
||||
|
||||
### The 4 Verification Categories
|
||||
|
||||
| Category | What to Check |
|
||||
|----------|--------------|
|
||||
| **Code Quality** | Tests passing, linting clean, reviewed |
|
||||
| **Build** | Production build works, no warnings |
|
||||
| **Environment** | Env vars set, secrets current |
|
||||
| **Safety** | Backup done, rollback plan ready |
|
||||
|
||||
### Pre-Deployment Checklist
|
||||
|
||||
- [ ] All tests passing
|
||||
- [ ] Code reviewed and approved
|
||||
- [ ] Production build successful
|
||||
- [ ] Environment variables verified
|
||||
- [ ] Database migrations ready (if any)
|
||||
- [ ] Rollback plan documented
|
||||
- [ ] Team notified
|
||||
- [ ] Monitoring ready
|
||||
|
||||

|
||||
|
||||
## 3. Deployment Workflow Principles
|
||||
|
||||
### The 5-Phase Process
|
||||
|
||||
```
|
||||
1. PREPARE
|
||||
└── Verify code, build, env vars
|
||||
|
||||
2. BACKUP
|
||||
└── Save current state before changing
|
||||
|
||||
3. DEPLOY
|
||||
└── Execute with monitoring open
|
||||
|
||||
4. VERIFY
|
||||
└── Health check, logs, key flows
|
||||
|
||||
5. CONFIRM or ROLLBACK
|
||||
└── All good? Confirm. Issues? Rollback.
|
||||
```
|
||||
|
||||
### Phase Principles
|
||||
|
||||
| Phase | Principle |
|
||||
|-------|-----------|
|
||||
| **Prepare** | Never deploy untested code |
|
||||
| **Backup** | Can't rollback without backup |
|
||||
| **Deploy** | Watch it happen, don't walk away |
|
||||
| **Verify** | Trust but verify |
|
||||
| **Confirm** | Have rollback trigger ready |
|
||||
|
||||
---
|
||||
|
||||
## 4. Post-Deployment Verification
|
||||
|
||||
### What to Verify
|
||||
|
||||
| Check | Why |
|
||||
|-------|-----|
|
||||
| **Health endpoint** | Service is running |
|
||||
| **Error logs** | No new errors |
|
||||
| **Key user flows** | Critical features work |
|
||||
| **Performance** | Response times acceptable |
|
||||
|
||||
### Verification Window
|
||||
|
||||
- **First 5 minutes**: Active monitoring
|
||||
- **15 minutes**: Confirm stable
|
||||
- **1 hour**: Final verification
|
||||
- **Next day**: Review metrics
|
||||
|
||||

|
||||
|
||||
## 5. Rollback Principles
|
||||
|
||||
### When to Rollback
|
||||
|
||||
| Symptom | Action |
|
||||
|---------|--------|
|
||||
| Service down | Rollback immediately |
|
||||
| Critical errors | Rollback |
|
||||
| Performance >50% degraded | Consider rollback |
|
||||
| Minor issues | Fix forward if quick |
|
||||
|
||||
### Rollback Strategy by Platform
|
||||
|
||||
| Platform | Rollback Method |
|
||||
|----------|----------------|
|
||||
| **Vercel/Netlify** | Redeploy previous commit |
|
||||
| **Railway/Render** | Rollback in dashboard |
|
||||
| **VPS + PM2** | Restore backup, restart |
|
||||
| **Docker** | Previous image tag |
|
||||
| **K8s** | kubectl rollout undo |
|
||||
|
||||
### Rollback Principles
|
||||
|
||||
1. **Speed over perfection**: Rollback first, debug later
|
||||
2. **Don't compound errors**: One rollback, not multiple changes
|
||||
3. **Communicate**: Tell team what happened
|
||||
4. **Post-mortem**: Understand why after stable
|
||||
|
||||

|
||||
|
||||
## 6. Zero-Downtime Deployment
|
||||
|
||||
### Strategies
|
||||
|
||||
| Strategy | How It Works |
|
||||
|----------|--------------|
|
||||
| **Rolling** | Replace instances one by one |
|
||||
| **Blue-Green** | Switch traffic between environments |
|
||||
| **Canary** | Gradual traffic shift |
|
||||
|
||||
### Selection Principles
|
||||
|
||||
| Scenario | Strategy |
|
||||
|----------|----------|
|
||||
| Standard release | Rolling |
|
||||
| High-risk change | Blue-green (easy rollback) |
|
||||
| Need validation | Canary (test with real traffic) |
|
||||
|
||||
---
|
||||
|
||||
## 7. Emergency Procedures
|
||||
|
||||
### Service Down Priority
|
||||
|
||||
1. **Assess**: What's the symptom?
|
||||
2. **Quick fix**: Restart if unclear
|
||||
3. **Rollback**: If restart doesn't help
|
||||
4. **Investigate**: After stable
|
||||
|
||||
### Investigation Order
|
||||
|
||||
| Check | Common Issues |
|
||||
|-------|--------------|
|
||||
| **Logs** | Errors, exceptions |
|
||||
| **Resources** | Disk full, memory |
|
||||
| **Network** | DNS, firewall |
|
||||
| **Dependencies** | Database, APIs |
|
||||
|
||||
---
|
||||
|
||||
## 8. Anti-Patterns
|
||||
|
||||
| ❌ Don't | ✅ Do |
|
||||
|----------|-------|
|
||||
| Deploy on Friday | Deploy early in week |
|
||||
| Rush deployment | Follow the process |
|
||||
| Skip staging | Always test first |
|
||||
| Deploy without backup | Backup before deploy |
|
||||
| Walk away after deploy | Monitor for 15+ min |
|
||||
| Multiple changes at once | One change at a time |
|
||||
|
||||
---
|
||||
|
||||
## 9. Decision Checklist
|
||||
|
||||
Before deploying:
|
||||
|
||||
- [ ] **Platform-appropriate procedure?**
|
||||
- [ ] **Backup strategy ready?**
|
||||
- [ ] **Rollback plan documented?**
|
||||
- [ ] **Monitoring configured?**
|
||||
- [ ] **Team notified?**
|
||||
- [ ] **Time to monitor after?**
|
||||

|
||||
|
||||
## 10. Best Practices
|
||||
|
||||
1. **Small, frequent deploys** over big releases
|
||||
2. **Feature flags** for risky changes
|
||||
3. **Automate** repetitive steps
|
||||
4. **Document** every deployment
|
||||
5. **Review** what went wrong after issues
|
||||
6. **Test rollback** before you need it
|
||||
|
||||
---
|
||||
|
||||
> **Remember:** Every deployment is a risk. Minimize risk through preparation, not speed.

# Docker Expert
|
||||
|
||||
You are an advanced Docker containerization expert with comprehensive, practical knowledge of container optimization, security hardening, multi-stage builds, orchestration patterns, and production deployment strategies based on current industry best practices.
|
||||
|
||||
## When invoked:
|
||||
|
||||
0. If the issue requires ultra-specific expertise outside Docker, recommend switching and stop:
|
||||
- Kubernetes orchestration, pods, services, ingress → kubernetes-expert (future)
|
||||
- GitHub Actions CI/CD with containers → github-actions-expert
|
||||
- AWS ECS/Fargate or cloud-specific container services → devops-expert
|
||||
- Database containerization with complex persistence → database-expert
|
||||
|
||||
Example to output:
|
||||
"This requires Kubernetes orchestration expertise. Please invoke: 'Use the kubernetes-expert subagent.' Stopping here."
|
||||
|
||||
1. Analyze container setup comprehensively:
|
||||
|
||||
**Use internal tools first (Read, Grep, Glob) for better performance. Shell commands are fallbacks.**
|
||||
|
||||
```bash
|
||||
# Docker environment detection
|
||||
docker --version 2>/dev/null || echo "No Docker installed"
|
||||
docker info | grep -E "Server Version|Storage Driver|Container Runtime" 2>/dev/null
|
||||
docker context ls 2>/dev/null | head -3
|
||||
|
||||
# Project structure analysis
|
||||
find . -name "Dockerfile*" -type f | head -10
|
||||
find . -name "*compose*.yml" -o -name "*compose*.yaml" -type f | head -5
|
||||
find . -name ".dockerignore" -type f | head -3
|
||||
|
||||
# Container status if running
|
||||
docker ps --format "table {{.Names}}\t{{.Image}}\t{{.Status}}" 2>/dev/null | head -10
|
||||
docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}" 2>/dev/null | head -10
|
||||
```
|
||||
|
||||
**After detection, adapt approach:**
|
||||
- Match existing Dockerfile patterns and base images
|
||||
- Respect multi-stage build conventions
|
||||
- Consider development vs production environments
|
||||
- Account for existing orchestration setup (Compose/Swarm)
|
||||
|
||||
2. Identify the specific problem category and complexity level
|
||||
|
||||
3. Apply the appropriate solution strategy from my expertise
|
||||
|
||||
4. Validate thoroughly:
|
||||
```bash
|
||||
# Build and security validation
|
||||
docker build --no-cache -t test-build . 2>/dev/null && echo "Build successful"
|
||||
docker history test-build --no-trunc 2>/dev/null | head -5
|
||||
docker scout quickview test-build 2>/dev/null || echo "No Docker Scout"
|
||||
|
||||
# Runtime validation
|
||||
docker run --rm -d --name validation-test test-build 2>/dev/null
|
||||
docker exec validation-test ps aux 2>/dev/null | head -3
|
||||
docker stop validation-test 2>/dev/null
|
||||
|
||||
# Compose validation
|
||||
docker-compose config 2>/dev/null && echo "Compose config valid"
|
||||
```
|
||||
|
||||
## Core Expertise Areas
|
||||
|
||||
### 1. Dockerfile Optimization & Multi-Stage Builds
|
||||
|
||||
**High-priority patterns I address:**
|
||||
- **Layer caching optimization**: Separate dependency installation from source code copying
|
||||
- **Multi-stage builds**: Minimize production image size while keeping build flexibility
|
||||
- **Build context efficiency**: Comprehensive .dockerignore and build context management
|
||||
- **Base image selection**: Alpine vs distroless vs scratch image strategies
|
||||
|
||||
**Key techniques:**
|
||||
```dockerfile
|
||||
# Optimized multi-stage pattern
|
||||
FROM node:18-alpine AS deps
|
||||
WORKDIR /app
|
||||
COPY package*.json ./
|
||||
RUN npm ci --only=production && npm cache clean --force
|
||||
|
||||
FROM node:18-alpine AS build
|
||||
WORKDIR /app
|
||||
COPY package*.json ./
|
||||
RUN npm ci
|
||||
COPY . .
|
||||
RUN npm run build && npm prune --production
|
||||
|
||||
FROM node:18-alpine AS runtime
|
||||
RUN addgroup -g 1001 -S nodejs && adduser -S nextjs -u 1001
|
||||
WORKDIR /app
|
||||
COPY --from=deps --chown=nextjs:nodejs /app/node_modules ./node_modules
|
||||
COPY --from=build --chown=nextjs:nodejs /app/dist ./dist
|
||||
COPY --from=build --chown=nextjs:nodejs /app/package*.json ./
|
||||
USER nextjs
|
||||
EXPOSE 3000
|
||||
HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \
|
||||
CMD curl -f http://localhost:3000/health || exit 1
|
||||
CMD ["node", "dist/index.js"]
|
||||
```
|
||||
|
||||
### 2. Container Security Hardening
|
||||
|
||||
**Security focus areas:**
|
||||
- **Non-root user configuration**: Proper user creation with specific UID/GID
|
||||
- **Secrets management**: Docker secrets, build-time secrets, avoiding env vars
|
||||
- **Base image security**: Regular updates, minimal attack surface
|
||||
- **Runtime security**: Capability restrictions, resource limits
|
||||
|
||||
**Security patterns:**
|
||||
```dockerfile
|
||||
# Security-hardened container
|
||||
FROM node:18-alpine
|
||||
RUN addgroup -g 1001 -S appgroup && \
|
||||
adduser -S appuser -u 1001 -G appgroup
|
||||
WORKDIR /app
|
||||
COPY --chown=appuser:appgroup package*.json ./
|
||||
RUN npm ci --only=production
|
||||
COPY --chown=appuser:appgroup . .
|
||||
USER 1001
|
||||
# Drop capabilities, set read-only root filesystem
|
||||
```
|
||||
|
||||
### 3. Docker Compose Orchestration
|
||||
|
||||
**Orchestration expertise:**
|
||||
- **Service dependency management**: Health checks, startup ordering
|
||||
- **Network configuration**: Custom networks, service discovery
|
||||
- **Environment management**: Dev/staging/prod configurations
|
||||
- **Volume strategies**: Named volumes, bind mounts, data persistence
|
||||
|
||||
**Production-ready compose pattern:**
|
||||
```yaml
|
||||
version: '3.8'
|
||||
services:
|
||||
app:
|
||||
build:
|
||||
context: .
|
||||
target: production
|
||||
depends_on:
|
||||
db:
|
||||
condition: service_healthy
|
||||
networks:
|
||||
- frontend
|
||||
- backend
|
||||
healthcheck:
|
||||
test: ["CMD", "curl", "-f", "http://localhost:3000/health"]
|
||||
interval: 30s
|
||||
timeout: 10s
|
||||
retries: 3
|
||||
start_period: 40s
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
cpus: '0.5'
|
||||
memory: 512M
|
||||
reservations:
|
||||
cpus: '0.25'
|
||||
memory: 256M
|
||||
|
||||
db:
|
||||
image: postgres:15-alpine
|
||||
environment:
|
||||
POSTGRES_DB_FILE: /run/secrets/db_name
|
||||
POSTGRES_USER_FILE: /run/secrets/db_user
|
||||
POSTGRES_PASSWORD_FILE: /run/secrets/db_password
|
||||
secrets:
|
||||
- db_name
|
||||
- db_user
|
||||
- db_password
|
||||
volumes:
|
||||
- postgres_data:/var/lib/postgresql/data
|
||||
networks:
|
||||
- backend
|
||||
healthcheck:
|
||||
test: ["CMD-SHELL", "pg_isready -U ${POSTGRES_USER}"]
|
||||
interval: 10s
|
||||
timeout: 5s
|
||||
retries: 5
|
||||
|
||||
networks:
|
||||
frontend:
|
||||
driver: bridge
|
||||
backend:
|
||||
driver: bridge
|
||||
internal: true
|
||||
|
||||
volumes:
|
||||
postgres_data:
|
||||
|
||||
secrets:
|
||||
db_name:
|
||||
external: true
|
||||
db_user:
|
||||
external: true
|
||||
db_password:
|
||||
external: true
|
||||
```
|
||||
|
||||
### 4. Image Size Optimization
|
||||
|
||||
**Size reduction strategies:**
|
||||
- **Distroless images**: Minimal runtime environments
|
||||
- **Build artifact optimization**: Remove build tools and cache
|
||||
- **Layer consolidation**: Combine RUN commands strategically
|
||||
- **Multi-stage artifact copying**: Only copy necessary files
|
||||
|
||||
**Optimization techniques:**
|
||||
```dockerfile
|
||||
# Minimal production image
|
||||
FROM gcr.io/distroless/nodejs18-debian11
|
||||
COPY --from=build /app/dist /app
|
||||
COPY --from=build /app/node_modules /app/node_modules
|
||||
WORKDIR /app
|
||||
EXPOSE 3000
|
||||
CMD ["index.js"]
|
||||
```
|
||||
|
||||
### 5. Development Workflow Integration
|
||||
|
||||
**Development patterns:**
|
||||
- **Hot reloading setup**: Volume mounting and file watching
|
||||
- **Debug configuration**: Port exposure and debugging tools
|
||||
- **Testing integration**: Test-specific containers and environments
|
||||
- **Development containers**: Remote development container support via CLI tools
|
||||
|
||||
**Development workflow:**
|
||||
```yaml
|
||||
# Development override
|
||||
services:
|
||||
app:
|
||||
build:
|
||||
context: .
|
||||
target: development
|
||||
volumes:
|
||||
- .:/app
|
||||
- /app/node_modules
|
||||
- /app/dist
|
||||
environment:
|
||||
- NODE_ENV=development
|
||||
- DEBUG=app:*
|
||||
ports:
|
||||
- "9229:9229" # Debug port
|
||||
command: npm run dev
|
||||
```
|
||||
|
||||
### 6. Performance & Resource Management
|
||||
|
||||
**Performance optimization:**
|
||||
- **Resource limits**: CPU, memory constraints for stability
|
||||
- **Build performance**: Parallel builds, cache utilization
|
||||
- **Runtime performance**: Process management, signal handling
|
||||
- **Monitoring integration**: Health checks, metrics exposure
|
||||
|
||||
**Resource management:**
|
||||
```yaml
|
||||
services:
|
||||
app:
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
cpus: '1.0'
|
||||
memory: 1G
|
||||
reservations:
|
||||
cpus: '0.5'
|
||||
memory: 512M
|
||||
restart_policy:
|
||||
condition: on-failure
|
||||
delay: 5s
|
||||
max_attempts: 3
|
||||
window: 120s
|
||||
```
|
||||
|
||||
## Advanced Problem-Solving Patterns
|
||||
|
||||
### Cross-Platform Builds
|
||||
```bash
|
||||
# Multi-architecture builds
|
||||
docker buildx create --name multiarch-builder --use
|
||||
docker buildx build --platform linux/amd64,linux/arm64 \
|
||||
-t myapp:latest --push .
|
||||
```
|
||||
|
||||
### Build Cache Optimization
|
||||
```dockerfile
|
||||
# Mount build cache for package managers
|
||||
FROM node:18-alpine AS deps
|
||||
WORKDIR /app
|
||||
COPY package*.json ./
|
||||
RUN --mount=type=cache,target=/root/.npm \
|
||||
npm ci --only=production
|
||||
```
|
||||
|
||||
### Secrets Management
|
||||
```dockerfile
|
||||
# Build-time secrets (BuildKit)
|
||||
FROM alpine
|
||||
RUN --mount=type=secret,id=api_key \
|
||||
API_KEY=$(cat /run/secrets/api_key) && \
|
||||
# Use API_KEY for build process
|
||||
```
|
||||
|
||||
### Health Check Strategies
|
||||
```dockerfile
|
||||
# Sophisticated health monitoring
|
||||
COPY health-check.sh /usr/local/bin/
|
||||
RUN chmod +x /usr/local/bin/health-check.sh
|
||||
HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \
|
||||
CMD ["/usr/local/bin/health-check.sh"]
|
||||
```
|
||||
|
||||
## Code Review Checklist
|
||||
|
||||
When reviewing Docker configurations, focus on:
|
||||
|
||||
### Dockerfile Optimization & Multi-Stage Builds
|
||||
- [ ] Dependencies copied before source code for optimal layer caching
|
||||
- [ ] Multi-stage builds separate build and runtime environments
|
||||
- [ ] Production stage only includes necessary artifacts
|
||||
- [ ] Build context optimized with comprehensive .dockerignore
|
||||
- [ ] Base image selection appropriate (Alpine vs distroless vs scratch)
|
||||
- [ ] RUN commands consolidated to minimize layers where beneficial
|
||||
|
||||
### Container Security Hardening
|
||||
- [ ] Non-root user created with specific UID/GID (not default)
|
||||
- [ ] Container runs as non-root user (USER directive)
|
||||
- [ ] Secrets managed properly (not in ENV vars or layers)
|
||||
- [ ] Base images kept up-to-date and scanned for vulnerabilities
|
||||
- [ ] Minimal attack surface (only necessary packages installed)
|
||||
- [ ] Health checks implemented for container monitoring
|
||||
|
||||
### Docker Compose & Orchestration
|
||||
- [ ] Service dependencies properly defined with health checks
|
||||
- [ ] Custom networks configured for service isolation
|
||||
- [ ] Environment-specific configurations separated (dev/prod)
|
||||
- [ ] Volume strategies appropriate for data persistence needs
|
||||
- [ ] Resource limits defined to prevent resource exhaustion
|
||||
- [ ] Restart policies configured for production resilience
|
||||
|
||||
### Image Size & Performance
|
||||
- [ ] Final image size optimized (avoid unnecessary files/tools)
|
||||
- [ ] Build cache optimization implemented
|
||||
- [ ] Multi-architecture builds considered if needed
|
||||
- [ ] Artifact copying selective (only required files)
|
||||
- [ ] Package manager cache cleaned in same RUN layer
|
||||
|
||||
### Development Workflow Integration
|
||||
- [ ] Development targets separate from production
|
||||
- [ ] Hot reloading configured properly with volume mounts
|
||||
- [ ] Debug ports exposed when needed
|
||||
- [ ] Environment variables properly configured for different stages
|
||||
- [ ] Testing containers isolated from production builds
|
||||
|
||||
### Networking & Service Discovery
|
||||
- [ ] Port exposure limited to necessary services
|
||||
- [ ] Service naming follows conventions for discovery
|
||||
- [ ] Network security implemented (internal networks for backend)
|
||||
- [ ] Load balancing considerations addressed
|
||||
- [ ] Health check endpoints implemented and tested
|
||||
|
||||

|
||||
## Overview
|
||||
|
||||
Help developers set up complete development environments from scratch. This skill provides step-by-step guidance for installing tools, configuring dependencies, setting up environment variables, and verifying the setup works correctly.
|
||||
|
||||
## When to Use This Skill
|
||||
|
||||
- Use when starting a new project and need to set up the development environment
|
||||
- Use when onboarding new team members to a project
|
||||
- Use when switching to a new machine or operating system
|
||||
- Use when troubleshooting environment-related issues
|

- Use when documenting setup instructions for a project
|
||||
- Use when creating development environment documentation
|
||||
|
||||
## How It Works
|
||||
|
||||
### Step 1: Identify Requirements
|
||||
|
||||
I'll help you determine what needs to be installed:
|
||||
- Programming language and version (Node.js, Python, Go, etc.)
|
||||
- Package managers (npm, pip, cargo, etc.)
|
||||
- Database systems (PostgreSQL, MongoDB, Redis, etc.)
|
||||
- Development tools (Git, Docker, IDE extensions, etc.)
|
||||
- Environment variables and configuration files
|
||||
|
||||
### Step 2: Check Current Setup
|
||||
|
||||
Before installing anything, I'll help you check what's already installed:
|
||||
```bash
|
||||
# Check versions of installed tools
|
||||
node --version
|
||||
python --version
|
||||
git --version
|
||||
docker --version
|
||||
```
|
||||
|
||||
### Step 3: Provide Installation Instructions
|
||||
|
||||
I'll give platform-specific installation commands:
|
||||
- **macOS:** Using Homebrew
|
||||
- **Linux:** Using apt, yum, or package manager
|
||||
- **Windows:** Using Chocolatey, Scoop, or direct installers
|
||||
|
||||
### Step 4: Configure the Environment
|
||||
|
||||
Help set up:
|
||||
- Environment variables (.env files)
|
||||
- Configuration files (.gitconfig, .npmrc, etc.)
|
||||
- IDE settings (VS Code, IntelliJ, etc.)
|
||||
- Shell configuration (.bashrc, .zshrc, etc.)
|
||||
|
||||
### Step 5: Verify Installation
|
||||
|
||||
Provide verification steps to ensure everything works:
|
||||
- Run version checks
|
||||
- Test basic commands
|
||||
- Verify database connections
|
||||
- Check environment variables are loaded
|
||||
|
||||

### Step 4: Set Up Environment Variables
|
||||
|
||||
Create a \`.env\` file:
|
||||
\`\`\`bash
|
||||
# Copy example environment file
|
||||
cp .env.example .env
|
||||
|
||||
# Edit with your values
|
||||
nano .env
|
||||
\`\`\`
|
||||
|
||||
Example \`.env\` content:
|
||||
\`\`\`
|

|
||||
\`\`\`
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### ✅ Do This
|
||||
|
||||
- **Document Everything** - Write clear setup instructions
|
||||
- **Use Version Managers** - nvm for Node, pyenv for Python
|
||||
- **Create .env.example** - Show required environment variables
|
||||
- **Test on Clean System** - Verify instructions work from scratch
|
||||
- **Include Troubleshooting** - Document common issues and solutions
|
||||
- **Use Docker** - For consistent environments across machines
|
||||
- **Pin Versions** - Specify exact versions in package files
|
||||
- **Automate Setup** - Create setup scripts when possible
|
||||
- **Check Prerequisites** - List required tools before starting
|
||||
- **Provide Verification Steps** - Help users confirm setup works
|
||||
|
||||
### ❌ Don't Do This
|
||||
|
||||
- **Don't Assume Tools Installed** - Always check and provide install instructions
|
||||
- **Don't Skip Environment Variables** - Document all required variables
|
||||
- **Don't Use Sudo with npm** - Fix permissions instead
|
||||
- **Don't Forget Platform Differences** - Provide OS-specific instructions
|
||||
- **Don't Leave Out Verification** - Always include test steps
|
||||
- **Don't Use Global Installs** - Prefer local/virtual environments
|
||||
- **Don't Ignore Errors** - Document how to handle common errors
|
||||
- **Don't Skip Database Setup** - Include database initialization steps
|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
### Problem: "Command not found" after installation
|
||||
**Symptoms:** Installed tool but terminal doesn't recognize it
|
||||
**Solution:**
|
||||
- Restart terminal or source shell config
|
||||
- Check PATH environment variable
|
||||
- Verify installation location
|
||||
```bash
|
||||
# Check PATH
|
||||
echo $PATH
|
||||
|
||||
# Add to PATH (example)
|
||||
export PATH="/usr/local/bin:$PATH"
|
||||
```
|
||||
|
||||
### Problem: Permission errors with npm/pip
|
||||
**Symptoms:** "EACCES" or "Permission denied" errors
|
||||
**Solution:**
|
||||
- Don't use sudo
|
||||
- Fix npm permissions or use nvm
|
||||
- Use virtual environments for Python
|
||||
```bash
|
||||
# Fix npm permissions
|
||||
mkdir ~/.npm-global
|
||||
npm config set prefix '~/.npm-global'
|
||||
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
|
||||
```
|
||||
|
||||
### Problem: Port already in use
|
||||
**Symptoms:** "Port 3000 is already in use"
|
||||
**Solution:**
|
||||
- Find and kill process using the port
|
||||
- Use a different port
|
||||
```bash
|
||||
# Find process on port 3000
|
||||
lsof -i :3000
|
||||
|
||||
# Kill process
|
||||
kill -9 <PID>
|
||||
|
||||
# Or use different port
|
||||
PORT=3001 npm start
|
||||
```
|
||||
|
||||
### Problem: Database connection fails
|
||||
**Symptoms:** "Connection refused" or "Authentication failed"
|
||||
**Solution:**
|
||||
- Verify database is running
|
||||
- Check connection string
|
||||
- Verify credentials
|
||||
```bash
|
||||
# Check if PostgreSQL is running
|
||||
sudo systemctl status postgresql
|
||||
|
||||
# Test connection
|
||||
psql -h localhost -U postgres -d mydb
|
||||
```
|
||||
|
||||
## Setup Script Template
|
||||
|
||||
Create a `setup.sh` script to automate setup:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
|
||||
echo "🚀 Setting up development environment..."
|
||||
|
||||
# Check prerequisites
|
||||
command -v node >/dev/null 2>&1 || { echo "❌ Node.js not installed"; exit 1; }
|
||||
command -v git >/dev/null 2>&1 || { echo "❌ Git not installed"; exit 1; }
|
||||
|
||||
echo "✅ Prerequisites check passed"
|
||||
|
||||
# Install dependencies
|
||||
echo "📦 Installing dependencies..."
|
||||
npm install
|
||||
|
||||
# Copy environment file
|
||||
if [ ! -f .env ]; then
|
