||||||
|
### CI/CD Platforms
|
||||||
|
- **GitHub Actions**: Workflows, actions, matrix builds
|
||||||
|
- **GitLab CI**: Pipelines, templates, includes
|
||||||
|
- **Jenkins**: Declarative/scripted pipelines
|
||||||
|
- **CircleCI**: Config, orbs, workflows
|
||||||
|
- **Azure DevOps**: YAML pipelines, stages
|
||||||
|

|
||||||
|
- Automated testing (unit, integration, E2E)
|
||||||
|
- Code quality checks (linting, formatting)
|
||||||
|
- Security scanning (SAST, DAST, dependencies)
|
||||||
|
- Docker image building and pushing
|
||||||
|
- Artifact management
|
||||||
|

### 2. Matrix Builds
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Test multiple versions/configurations
|
||||||
|
test:
|
||||||
|
name: Test (Node ${{ matrix.node }} on ${{ matrix.os }})
|
||||||
|
runs-on: ${{ matrix.os }}
|
||||||
|
strategy:
|
||||||
|
# Don't cancel other jobs if one fails
|
||||||
|
fail-fast: false
|
||||||
|
matrix:
|
||||||
|
os: [ubuntu-latest, windows-latest, macos-latest]
|
||||||
|
node: [18, 20, 21]
|
||||||
|
# Exclude specific combinations
|
||||||
|
exclude:
|
||||||
|
- os: windows-latest
|
||||||
|
node: 18
|
||||||
|
# Include specific combinations
|
||||||
|
include:
|
||||||
|
- os: ubuntu-latest
|
||||||
|
node: 20
|
||||||
|
coverage: true
|
||||||
|
|
||||||
|
steps:
|
||||||
|
- uses: actions/checkout@v4
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
- name: Install dependencies
|
||||||
|
run: npm ci
|
||||||
|
|
||||||
|
- name: Run tests
|
||||||
|
run: npm test
|
||||||
|
env:

### 3. Caching Strategies
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
cache-dependencies:
|
||||||
|
runs-on: ubuntu-latest
|
||||||
|
steps:
|
||||||
|
- uses: actions/checkout@v4
|
||||||
|
|
||||||
|
# Cache npm dependencies
|
||||||
|
- name: Cache node modules
|
||||||
|
uses: actions/cache@v3
|
||||||
|
with:
|
||||||
|
path: |
|
||||||
|
~/.npm
|
||||||
|
node_modules
|
||||||
|
key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
|
||||||
|
restore-keys: |
|
||||||
|
${{ runner.os }}-node-
|
||||||
|
|
||||||
|
# Cache build outputs
|
||||||
|
- name: Cache build
|
||||||
|
uses: actions/cache@v3
|
||||||
|
with:
|
||||||
|
path: |
|
||||||
|
.next/cache
|
||||||
|
dist
|
||||||
|
key: ${{ runner.os }}-build-${{ github.sha }}
|
||||||
|
restore-keys: |
|
||||||
|
${{ runner.os }}-build-
|
||||||
|
|
||||||
|
# Docker layer caching
|
||||||
|
- name: Set up Docker Buildx
|
||||||
|
uses: docker/setup-buildx-action@v3
|
||||||
|
|
||||||
|
- name: Build with cache
|
||||||
|
uses: docker/build-push-action@v5
|
||||||
|
with:
|
||||||
|
context: .
|
||||||
|
cache-from: type=gha
|
||||||
|
cache-to: type=gha,mode=max
|
||||||
|
push: false
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Conditional Execution
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
deploy:
|
||||||
|
runs-on: ubuntu-latest
|
||||||
|
# Only deploy from main branch
|
||||||
|
if: github.ref == 'refs/heads/main' && github.event_name == 'push'
|
||||||
|
|
||||||
|
steps:
|
||||||
|
- name: Deploy to staging
|
||||||
|
if: contains(github.event.head_commit.message, '[deploy-staging]')
|
||||||
|
run: ./scripts/deploy-staging.sh
|
||||||
|
|
||||||
|
- name: Deploy to production
|
||||||
|
if: startsWith(github.ref, 'refs/tags/v')
|
||||||
|
run: ./scripts/deploy-production.sh
|
||||||
|
|
||||||
|
# Different job based on file changes
|
||||||
|
- uses: dorny/paths-filter@v2
|
||||||
|
id: changes
|
||||||
|
with:
|
||||||
|
filters: |
|
||||||
|
frontend:
|
||||||
|
- 'src/frontend/**'
|
||||||
|
backend:
|
||||||
|
- 'src/backend/**'
|
||||||
|
|
||||||
|
- name: Deploy frontend
|
||||||
|
if: steps.changes.outputs.frontend == 'true'
|
||||||
|
run: ./scripts/deploy-frontend.sh
|
||||||
|
|
||||||
|
- name: Deploy backend
|
||||||
|
if: steps.changes.outputs.backend == 'true'
|
||||||
|
run: ./scripts/deploy-backend.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5. Custom Actions
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# .github/actions/setup-project/action.yml
|
||||||
|

|
||||||
|
cache-dependency-path:
|
||||||
|

|
||||||
|
required: false
|
||||||
|
default: '**/package-lock.json'
|
||||||
|
|
||||||
|
runs:
|
||||||
|
using: 'composite'
|
||||||
|
steps:
|
||||||
|
- name: Setup Node.js
|
||||||
|
uses: actions/setup-node@v4
|
||||||
|
with:
|
||||||
|
node-version: ${{ inputs.node-version }}
|
||||||
|
cache: 'npm'
|
||||||
|
cache-dependency-path: ${{ inputs.cache-dependency-path }}
|
||||||
|
|
||||||
|
- name: Install dependencies
|
||||||
|
shell: bash
|
||||||
|
run: npm ci
|
||||||
|
|
||||||
|
- name: Verify installation
|
||||||
|
shell: bash
|
||||||
|
run: |
|
||||||
|
node --version
|
||||||
|
npm --version
|
||||||
|
```
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Use the custom action
|
||||||
|
jobs:
|
||||||
|
build:
|
||||||
|
runs-on: ubuntu-latest
|
||||||
|
steps:
|
||||||
|
- uses: actions/checkout@v4
|
||||||
|
|
||||||
|
- name: Setup project
|
||||||
|
uses: ./.github/actions/setup-project
|
||||||
|
with:
|
||||||
|
node-version: '20'
|
||||||
|
```

## GitLab CI Best Practices
|
||||||
|
|
||||||
|
### 1. Template Organization
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# .gitlab-ci.yml
|
||||||
|
include:
|
||||||

|
||||||
|
- local: '.gitlab/ci/templates/deploy.yml'
|
||||||
|
|
||||||
|
stages:
|
||||||
|
- lint
|
||||||
|
- test
|
||||||
|
- build
|
||||||
|
- deploy
|
||||||
|
|
||||||
|
variables:
|
||||||
|
NODE_VERSION: "20"
|

|
deploy:staging:
|
||||||
|

|
||||||
|
only:
|
||||||
|
- main
|
||||||
|
```
|
||||||
|
|
||||||
|
```yaml
|
||||||
|

|
|
||||||
|
### 2. Dynamic Child Pipelines
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Generate dynamic pipeline based on changes
|
||||||
|
generate-pipeline:
|
||||||
|
stage: .pre
|
||||||
|
script:
|
||||||
|
- ./scripts/generate-pipeline.sh > pipeline.yml
|
||||||
|
artifacts:
|
||||||
|
paths:
|
||||||
|
- pipeline.yml
|
||||||
|
|
||||||
|
trigger-pipeline:
|
||||||
|
stage: .pre
|
||||||
|
needs: [generate-pipeline]
|
||||||
|
trigger:
|
||||||
|
include:
|
||||||
|
- artifact: pipeline.yml
|
||||||
|
job: generate-pipeline
|
||||||
|
strategy: depend
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Parallel Jobs with DAG
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Use directed acyclic graph for parallel execution
|
||||||
|
lint:
|
||||||
|
stage: lint
|
||||||
|
script: npm run lint
|
||||||
|
|
||||||
|
test:unit:
|
||||||
|
stage: test
|
||||||
|
needs: [] # Run immediately, don't wait for lint
|
||||||
|
script: npm run test:unit
|
||||||
|
|
||||||
|
test:integration:
|
||||||
|
stage: test
|
||||||
|
needs: [] # Run in parallel with unit tests
|
||||||
|
script: npm run test:integration
|
||||||
|
|
||||||
|
build:
|
||||||
|
stage: build
|
||||||
|
needs: [lint, test:unit, test:integration] # Wait for all tests
|
||||||
|
script: npm run build
|
||||||
|
```
|
||||||
|
|
||||||
|
## Jenkins Pipeline Best Practices
|
||||||
|
|
||||||
|
### 1. Declarative Pipeline
|
||||||
|
|
||||||
|
```groovy
|
||||||
|
// Jenkinsfile
|
||||||
|
pipeline {
|
||||||
|
agent any
|
||||||
|
|
||||||
|
options {
|
||||||
|
buildDiscarder(logRotator(numToKeepStr: '10'))
|
||||||
|
disableConcurrentBuilds()
|
||||||
|
timeout(time: 1, unit: 'HOURS')
|
||||||
|
timestamps()
|
||||||
|
}
|
||||||
|
|
||||||
|
environment {
|
||||||
|
NODE_VERSION = '20'
|
||||||
|
DOCKER_REGISTRY = credentials('docker-registry')
|
||||||
|
SLACK_WEBHOOK = credentials('slack-webhook')
|
||||||
|
}
|
||||||
|
|
||||||
|
parameters {
|

## Pipeline Optimization Techniques
|
||||||
|
|
||||||
|
### 1. Parallel Execution
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Run independent jobs in parallel
|
||||||
|
jobs:
|
||||||
|
lint:
|
||||||
|
# Linting doesn't depend on anything
|
||||||
|
|
||||||
|
test-unit:
|
||||||
|
# Unit tests don't depend on linting
|
||||||
|
|
||||||
|
test-integration:
|
||||||
|
# Integration tests don't depend on unit tests
|
||||||
|
|
||||||
|
build:
|
||||||
|
needs: [lint, test-unit, test-integration]
|
||||||
|
# Build only runs after all previous jobs pass
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Skip Redundant Work
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Only run jobs when relevant files change
|
||||||
|
test-frontend:
|
||||||
|
rules:
|
||||||
|
- changes:
|
||||||
|
- src/frontend/**/*
|
||||||
|
- package.json
|
||||||
|
|
||||||
|
test-backend:
|
||||||
|
rules:
|
||||||
|
- changes:
|
||||||
|
- src/backend/**/*
|
||||||
|
- requirements.txt
|
||||||
|
|
||||||
|
# Skip CI on docs-only changes
|
||||||
|
workflow:
|
||||||
|
rules:
|
||||||
|
- if: '$CI_COMMIT_MESSAGE =~ /\[skip ci\]/'
|
||||||
|
when: never
|
||||||
|
- changes:
|
||||||
|
- '**/*.md'
|
||||||
|
when: never
|
||||||
|
- when: always
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Artifacts and Dependencies
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
build:
|
||||||
|
script:
|
||||||
|
- npm run build
|
||||||
|
artifacts:
|
||||||
|
paths:
|
||||||
|
- dist/
|
||||||
|
expire_in: 1 hour
|
||||||
|
|
||||||
|
deploy:
|
||||||
|
needs:
|
||||||
|
- job: build
|
||||||
|
artifacts: true
|
||||||
|
script:
|
||||||
|
- ./deploy.sh dist/
|
||||||
|
```
|
||||||
|
|
||||||
|
## Security Best Practices
|
||||||
|
|
||||||
|
### 1. Secret Management
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# ❌ BAD: Hardcoded secrets
|
||||||
|
env:
|
||||||
|
DATABASE_URL: postgresql://user:password@localhost/db
|
||||||
|
|
||||||
|
# ✅ GOOD: Use secrets
|
||||||
|
env:
|
||||||
|
DATABASE_URL: ${{ secrets.DATABASE_URL }}
|
||||||
|
|
||||||
|
# ✅ BETTER: Mask secrets in logs
|
||||||
|
- name: Use secret
|
||||||
|
run: |
|
||||||
|
echo "::add-mask::${{ secrets.API_KEY }}"
|
||||||
|
./script.sh --api-key="${{ secrets.API_KEY }}"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Dependency Scanning
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
security-scan:
|
||||||
|
steps:
|
||||||
|
- name: Scan dependencies
|
||||||
|
run: npm audit --audit-level=moderate
|
||||||
|
|
||||||
|
- name: Scan with Snyk
|
||||||
|
uses: snyk/actions/node@master
|
||||||
|
env:
|
||||||
|
SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
|
||||||
|
|
||||||
|
- name: Scan Docker image
|
||||||
|
run: |
|
||||||
|
docker run --rm \
|
||||||
|
-v /var/run/docker.sock:/var/run/docker.sock \
|
||||||
|
aquasec/trivy:latest image myapp:latest
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. SAST/DAST
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
sast:
|
||||||
|
steps:
|
||||||
|
- name: Initialize CodeQL
|
||||||
|
uses: github/codeql-action/init@v2
|
||||||
|
with:
|
||||||
|
languages: javascript, typescript
|
||||||
|
|
||||||
|
- name: Perform CodeQL Analysis
|
||||||
|
uses: github/codeql-action/analyze@v2
|
||||||
|
```
|
||||||
|
|
||||||
|
## Monitoring and Alerts
|
||||||
|
|
||||||
|
### Pipeline Metrics to Track
|
||||||
|
|
||||||
|
- Build success rate
|
||||||
|
- Average build duration
|
||||||
|
- Test success rate
|
||||||
|
- Deployment frequency
|
||||||
|
- Mean time to recovery (MTTR)
|
||||||
|
- Change failure rate
|
||||||
|
|
||||||
|
### Notifications
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Slack notifications
|
||||||
|
- name: Notify Slack
|
||||||
|
uses: 8398a7/action-slack@v3
|
||||||
|
if: always()
|
||||||
|
with:
|
||||||
|
status: ${{ job.status }}
|
||||||
|
webhook_url: ${{ secrets.SLACK_WEBHOOK }}
|
||||||
|
fields: repo,message,commit,author,action,eventName,workflow
|
||||||
|
|
||||||
|
# Email notifications (GitLab)
|
||||||
|
notify:failure:
|
||||||
|
stage: .post
|
||||||
|
only:
|
||||||
|
- main
|
||||||
|
when: on_failure
|
||||||
|
script:
|
||||||
|
- ./scripts/send-alert-email.sh
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Dockerfile Best Practices
|
||||||
|
|
||||||
|
### 1. Multi-Stage Builds
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
# ❌ BAD: Single stage with dev dependencies
|
||||||
|
FROM node:20
|
||||||
|
WORKDIR /app
|
||||||
|
COPY . .
|
||||||
|
RUN npm install # Includes devDependencies
|
||||||
|
RUN npm run build
|
||||||
|
CMD ["node", "dist/main.js"]
|
||||||
|
|
||||||
|
# ✅ GOOD: Multi-stage build
|
||||||
|
FROM node:20-alpine AS builder
|
||||||
|
WORKDIR /app
|
||||||
|
COPY package*.json ./
|
||||||
|
RUN npm ci
|
||||||
|
COPY . .
|
||||||
|
RUN npm run build
|
||||||
|
|
||||||
|
FROM node:20-alpine AS production
|
||||||
|
WORKDIR /app
|
||||||
|
RUN addgroup -g 1001 nodejs && adduser -S nodejs -u 1001
|
||||||
|
COPY --from=builder --chown=nodejs:nodejs /app/dist ./dist
|
||||||
|
COPY --from=builder --chown=nodejs:nodejs /app/node_modules ./node_modules
|
||||||
|
COPY --chown=nodejs:nodejs package*.json ./
|
||||||
|
USER nodejs
|
||||||
|
EXPOSE 3000
|
||||||
|
CMD ["node", "dist/main.js"]
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Layer Caching
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
# ❌ BAD: Dependencies installed on every code change
|
||||||
|
FROM node:20-alpine
|
||||||
|
WORKDIR /app
|
||||||
|
COPY . .
|
||||||
|
RUN npm install # Runs even if only source code changed
|
||||||
|
|
||||||
|
# ✅ GOOD: Dependencies cached separately
|
||||||
|
FROM node:20-alpine
|
||||||
|
WORKDIR /app
|
||||||
|
COPY package*.json ./ # Copy only package files first
|
||||||
|
RUN npm ci # Cached unless package files change
|
||||||
|
COPY . . # Copy source code last
|
||||||
|
RUN npm run build
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Image Size Optimization
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
# ❌ BAD: Large image with unnecessary files
|
||||||
|
FROM node:20 # ~900MB
|
||||||
|
WORKDIR /app
|
||||||
|
COPY . .
|
||||||
|
RUN npm install && npm run build
|
||||||
|
|
||||||
|
# ✅ GOOD: Minimal image
|
||||||
|
FROM node:20-alpine AS builder # ~110MB
|
||||||
|
WORKDIR /app
|
||||||
|
COPY package*.json ./
|
||||||
|
RUN npm ci --only=production
|
||||||
|
COPY . .
|
||||||
|
RUN npm run build
|
||||||
|
|
||||||
|
FROM node:20-alpine # Production stage also small
|
||||||
|
WORKDIR /app
|
||||||
|
COPY --from=builder /app/dist ./dist
|
||||||
|
COPY --from=builder /app/node_modules ./node_modules
|
||||||
|
CMD ["node", "dist/main.js"]
|
||||||
|
|
||||||
|
# 🌟 BEST: Distroless for Go/static binaries
|
||||||
|
FROM golang:1.21-alpine AS builder
|
||||||
|
WORKDIR /app
|
||||||
|
COPY . .
|
||||||
|
RUN CGO_ENABLED=0 go build -ldflags="-w -s" -o main .
|
||||||
|
|
||||||
|
FROM gcr.io/distroless/static-debian11 # ~2MB
|
||||||
|
COPY --from=builder /app/main /
|
||||||
|
USER 65532:65532
|
||||||
|
ENTRYPOINT ["/main"]
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Security Practices
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
# Security-focused Dockerfile
|
||||||
|
FROM node:20-alpine AS builder
|
||||||
|
|
||||||
|
# Install only production dependencies
|
||||||
|
WORKDIR /app
|
||||||
|
COPY package*.json ./
|
||||||
|
RUN npm ci --only=production && \
|
||||||
|
npm cache clean --force
|
||||||
|
|
||||||
|
COPY . .
|
||||||
|
RUN npm run build
|
||||||
|
|
||||||
|
# Production stage
|
||||||
|
FROM node:20-alpine
|
||||||
|
|
||||||
|
# 1. Create non-root user
|
||||||
|
RUN addgroup -g 1001 nodejs && \
|
||||||
|
adduser -S nodejs -u 1001
|
||||||
|
|
||||||
|
WORKDIR /app
|
||||||
|
|
||||||
|
# 2. Set proper ownership
|
||||||
|
COPY --from=builder --chown=nodejs:nodejs /app/dist ./dist
|
||||||
|
COPY --from=builder --chown=nodejs:nodejs /app/node_modules ./node_modules
|
||||||
|
|
||||||
|
# 3. Switch to non-root user
|
||||||
|
USER nodejs
|
||||||
|
|
||||||
|
# 4. Use specific port (not privileged port)
|
||||||
|
EXPOSE 3000
|
||||||
|
|
||||||
|
# 5. Add health check
|
||||||
|
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
|
||||||
|
CMD node -e "require('http').get('http://localhost:3000/health', (r) => process.exit(r.statusCode === 200 ? 0 : 1))"
|
||||||
|
|
||||||
|
# 6. Use ENTRYPOINT for security
|
||||||
|
ENTRYPOINT ["node"]
|
||||||
|
CMD ["dist/main.js"]
|
||||||
|
|
||||||
|
# Security scan with Trivy
|
||||||
|
# docker build -t myapp .
|
||||||
|
# trivy image myapp
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5. Build Arguments and Labels
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
ARG NODE_VERSION=20
|
||||||
|
ARG BUILD_DATE
|
||||||
|
ARG VCS_REF
|
||||||
|
ARG VERSION=1.0.0
|
||||||
|
|
||||||
|
FROM node:${NODE_VERSION}-alpine
|
||||||
|
|
||||||
|
# OCI labels
|
||||||
|
LABEL org.opencontainers.image.created="${BUILD_DATE}" \
|

## Docker Commands & Operations
|
||||||
|
|
||||||
|
### Building Images
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Basic build
|
||||||
|
docker build -t myapp:latest .
|
||||||
|
|
||||||
|
# Build with specific Dockerfile
|
||||||
|
docker build -f Dockerfile.prod -t myapp:latest .
|
||||||
|
|
||||||
|
# Build with build args
|
||||||
|
docker build \
|
||||||
|
--build-arg NODE_VERSION=20 \
|
||||||
|
--build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') \
|
||||||
|
--build-arg VCS_REF=$(git rev-parse HEAD) \
|
||||||
|
-t myapp:latest .
|
||||||
|
|
||||||
|
# Build with target stage
|
||||||
|
docker build --target production -t myapp:latest .
|
||||||
|
|
||||||
|
# Build with no cache
|
||||||
|
docker build --no-cache -t myapp:latest .
|
||||||
|
|
||||||
|
# Multi-platform build
|
||||||
|
docker buildx build \
|
||||||
|
--platform linux/amd64,linux/arm64 \
|
||||||
|
-t myapp:latest \
|
||||||
|
--push .
|
||||||
|
```
|
||||||
|
|
||||||
|
### Running Containers
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Run with resource limits
|
||||||
|
docker run -d \
|
||||||
|
--name myapp \
|
||||||
|
--memory="512m" \
|
||||||
|
--cpus="1.0" \
|
||||||
|
--restart=unless-stopped \
|
||||||
|
-p 3000:3000 \
|
||||||
|
-e NODE_ENV=production \
|
||||||
|
myapp:latest
|
||||||
|
|
||||||
|
# Run with volume
|
||||||
|
docker run -d \
|
||||||
|
--name myapp \
|
||||||
|
-v $(pwd)/data:/app/data \
|
||||||
|
-v myapp-logs:/app/logs \
|
||||||
|
myapp:latest
|
||||||
|
|
||||||
|
# Run with network
|
||||||
|
docker run -d \
|
||||||
|
--name myapp \
|
||||||
|
--network=my-network \
|
||||||
|
myapp:latest
|
||||||
|
|
||||||
|
# Run with health check
|
||||||
|
docker run -d \
|
||||||
|
--name myapp \
|
||||||
|
--health-cmd="curl -f http://localhost:3000/health || exit 1" \
|
||||||
|
--health-interval=30s \
|
||||||
|
--health-timeout=3s \
|
||||||
|
--health-retries=3 \
|
||||||
|
myapp:latest
|
||||||
|
|
||||||
|
# Run as non-root
|
||||||
|
docker run -d \
|
||||||
|
--name myapp \
|
||||||
|
--user 1001:1001 \
|
||||||
|
myapp:latest
|
||||||
|
```
|
||||||
|
|
||||||
|
### Debugging
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# View logs
|
||||||
|
docker logs -f myapp
|
||||||
|
|
||||||
|
# View logs with timestamps
|
||||||
|
docker logs -f --timestamps myapp
|
||||||
|
|
||||||
|
# Execute command in running container
|
||||||
|
docker exec -it myapp sh
|
||||||
|
|
||||||
|
# Execute as root (for debugging)
|
||||||
|
docker exec -it --user root myapp sh
|
||||||
|
|
||||||
|
# Inspect container
|
||||||
|
docker inspect myapp
|
||||||
|
|
||||||
|
# View container stats
|
||||||
|
docker stats myapp
|
||||||
|
|
||||||
|
# View container processes
|
||||||
|
docker top myapp
|
||||||
|
|
||||||
|
# View container port mappings
|
||||||
|
docker port myapp
|
||||||
|
|
||||||
|
# View container resource usage
|
||||||
|
docker stats --no-stream myapp
|
||||||
|
```
|
||||||
|
|
||||||
|
### Cleanup
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Remove stopped containers
|
||||||
|
docker container prune
|
||||||
|
|
||||||
|
# Remove unused images
|
||||||
|
docker image prune
|
||||||
|
|
||||||
|
# Remove unused volumes
|
||||||
|
docker volume prune
|
||||||
|
|
||||||
|
# Remove everything unused
|
||||||
|
docker system prune -a
|
||||||
|
|
||||||
|
# Remove specific container
|
||||||
|
docker rm -f myapp
|
||||||
|
|
||||||
|
# Remove specific image
|
||||||
|
docker rmi myapp:latest
|
||||||
|
```
|
||||||
|
|
||||||
|
## Performance Optimization
|
||||||
|
|
||||||
|
### 1. Build Cache
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
# Use BuildKit for better caching
|
||||||
|
# syntax=docker/dockerfile:1
|
||||||
|
|
||||||
|
# Cache mount for package managers
|
||||||
|
FROM node:20-alpine AS builder
|
||||||
|
WORKDIR /app
|
||||||
|
COPY package*.json ./
|
||||||
|
RUN --mount=type=cache,target=/root/.npm \
|
||||||
|
npm ci
|
||||||
|
COPY . .
|
||||||
|
RUN npm run build
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Layer Optimization
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Before optimization: 500MB
|
||||||
|
FROM node:20
|
||||||
|
WORKDIR /app
|
||||||
|
COPY . .
|
||||||
|
RUN apt-get update
|
||||||
|
RUN apt-get install -y curl
|
||||||
|
RUN apt-get install -y git
|
||||||
|
RUN npm install
|
||||||
|
|
||||||
|
# After optimization: 150MB
|
||||||
|
FROM node:20-alpine
|
||||||
|
WORKDIR /app
|
||||||
|
RUN apk add --no-cache curl git
|
||||||
|
COPY package*.json ./
|
||||||
|
RUN npm ci --only=production
|
||||||
|
COPY . .
|
||||||
|
```
|
||||||
|
|
||||||
|
## Security Scanning
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Scan with Trivy
|
||||||
|
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \
|
||||||
|
aquasec/trivy:latest image myapp:latest
|
||||||
|
|
||||||
|
# Scan with Snyk
|
||||||
|
snyk container test myapp:latest
|
||||||
|
|
||||||
|
# Scan with Docker Scout
|
||||||
|
docker scout cves myapp:latest
|
||||||
|
|
||||||
|
# Scan for secrets
|
||||||
|
docker run --rm -v $(pwd):/scan trufflesecurity/trufflehog:latest \
|
||||||
|
filesystem /scan
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting Checklist
|
||||||
|
|
||||||
|
- [ ] Image size optimized (use alpine, multi-stage)
|
||||||
|
- [ ] Non-root user configured
|
||||||
|
- [ ] Health checks defined
|
||||||
|
- [ ] Resource limits set
|
||||||
|
- [ ] Proper logging configured
|
||||||
|
- [ ] .dockerignore created
|
||||||
|
- [ ] Secrets not in image
|
||||||
|
- [ ] Dependencies cached correctly
|
||||||
|
- [ ] Minimal layers used
|
||||||
|
- [ ] Security scans passing
|
||||||
|
|
||||||
|
Remember: Containers should be ephemeral, immutable, and follow the principle of least privilege.

# Setup CI/CD Pipeline Command
|
||||||
|
|
||||||
|
You are helping the user set up a CI/CD pipeline for automated testing, building, and deployment following Sngular's DevOps best practices.
|
||||||
|
|
||||||
|
## Instructions
|
||||||
|
|
||||||
|
1. **Determine the platform**:
|
||||||
|
- GitHub Actions
|
||||||
|
- GitLab CI
|
||||||
|
- Jenkins
|
||||||
|
- CircleCI
|
||||||
|
- Azure DevOps
|
||||||
|
- Bitbucket Pipelines
|
||||||
|
|
||||||
|
2. **Identify application type**:
|
||||||
|
- Node.js/TypeScript application
|
||||||
|
- Python application
|
||||||
|
- Go application
|
||||||
|
- Frontend application (React, Vue, Next.js)
|
||||||
|
- Full-stack application
|
||||||
|
- Monorepo with multiple services
|
||||||
|
|
||||||
|
3. **Ask about pipeline requirements**:
|
||||||
|
- Linting and code quality checks
|
||||||
|
- Unit and integration tests
|
||||||
|
- Build and compile steps
|
||||||
|
- Docker image building
|
||||||
|
- Deployment targets (staging, production)
|
||||||
|
- Security scanning
|
||||||
|
- Performance testing
|
||||||
|
|
||||||
|
4. **Determine trigger events**:
|
||||||
|
- Push to main/master
|
||||||
|
- Pull requests
|
||||||
|
- Tag/release creation
|
||||||
|
- Scheduled runs
|
||||||
|
- Manual triggers
|
||||||
|
|
||||||
|

### 1. Caching Dependencies
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# GitHub Actions
|
||||||
|
- name: Cache dependencies
|
||||||
|
uses: actions/cache@v3
|
||||||
|
with:
|
||||||
|
path: ~/.npm
|
||||||
|
key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
|
||||||
|
restore-keys: |
|
||||||
|
${{ runner.os }}-node-
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Matrix Builds
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Test multiple versions
|
||||||
|
strategy:
|
||||||
|
matrix:
|
||||||
|
node-version: [18, 20, 21]
|
||||||
|
os: [ubuntu-latest, windows-latest, macos-latest]
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Conditional Execution
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Only run on specific branches
|
||||||
|
if: github.ref == 'refs/heads/main'
|
||||||
|
|
||||||
|
# Only run for PRs
|
||||||
|
if: github.event_name == 'pull_request'
|
||||||
|
|
||||||
|
# Only run for tags
|
||||||
|
if: startsWith(github.ref, 'refs/tags/')
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Secrets Management
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Use secrets from repository settings
|
||||||
|
env:
|
||||||
|
DATABASE_URL: ${{ secrets.DATABASE_URL }}
|
||||||
|
API_KEY: ${{ secrets.API_KEY }}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5. Parallel Jobs
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Jobs run in parallel by default
|
||||||
|
jobs:
|
||||||
|
lint:
|
||||||
|
# ...
|
||||||
|
test:
|
||||||
|
# ...
|
||||||
|
security-scan:
|
||||||
|
# ...
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6. Job Dependencies
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
jobs:
|
||||||
|
test:
|
||||||
|
# ...
|
||||||
|
|
||||||
|
build:
|
||||||
|
needs: test # Wait for test to complete
|
||||||
|
# ...
|
||||||
|
|
||||||
|
deploy:
|
||||||
|
needs: [test, build] # Wait for multiple jobs
|
||||||
|
# ...
|
||||||
|
```
|
||||||
|
|
||||||
|
## Security Best Practices
|
||||||
|
|
||||||
|
- Store secrets in CI platform's secret management
|
||||||
|
- Use minimal permissions for CI tokens
|
||||||
|
- Scan dependencies for vulnerabilities
|
||||||
|
- Scan Docker images for security issues
|
||||||
|
- Don't log sensitive information
|
||||||
|
- Use branch protection rules
|
||||||
|
- Require status checks before merging
|
||||||
|
- Enable signed commits
|
||||||
|
|
||||||
|
## Monitoring and Notifications
|
||||||
|
|
||||||
|
### Slack Notifications (GitHub Actions)
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
- name: Slack Notification
|
||||||
|
uses: 8398a7/action-slack@v3
|
||||||
|
if: always()
|
||||||
|
with:
|
||||||
|
status: ${{ job.status }}
|
||||||
|
text: 'CI Pipeline ${{ job.status }}'
|
||||||
|
webhook_url: ${{ secrets.SLACK_WEBHOOK }}
|
||||||
|
```
|
||||||
|
|
||||||
|
Ask the user: "What CI/CD platform would you like to use?"

# Deploy Application Command
|
||||||
|
|
||||||
|
You are helping the user deploy their application to various platforms and orchestrators following Sngular's deployment best practices.
|
||||||
|
|
||||||
|
## Instructions
|
||||||
|
|
||||||
|
1. **Determine deployment target**:
|
||||||
|
- Kubernetes (K8s)
|
||||||
|
- Docker Swarm
|
||||||
|
- AWS (ECS, EKS, EC2, Lambda)
|
||||||
|
- Google Cloud (GKE, Cloud Run, App Engine)
|
||||||
|
- Azure (AKS, Container Instances, App Service)
|
||||||
|
- Vercel / Netlify (for frontend)
|
||||||
|
- Heroku
|
||||||
|
- DigitalOcean
|
||||||
|
- Railway
|
||||||
|
|
||||||
|
2. **Identify application type**:
|
||||||
|
- Containerized application (Docker)
|
||||||
|
- Serverless function
|
||||||
|
- Static site
|
||||||
|
- Full-stack application
|
||||||
|
- Microservices
|
||||||
|
|
||||||
|
3. **Ask about requirements**:
|
||||||
|
- Environment (staging, production)
|
||||||
|
- Scaling needs (replicas, auto-scaling)
|
||||||
|
- Resource limits (CPU, memory)
|
||||||
|
- Database / persistent storage
|
||||||
|
- Load balancing
|
||||||
|
- SSL/TLS certificates
|
||||||
|
- Domain configuration
|
||||||
|
- Monitoring and logging
|
||||||
|
|
||||||

|
|
||||||
|
### Rolling Update Script
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
# deploy.sh
|
||||||

||||||
|
--namespace=$ENVIRONMENT \
|
||||||
|
--timeout=5m
|
||||||
|
|
||||||
|
# Verify deployment
|
||||||
|
kubectl get pods \

--namespace=$ENVIRONMENT \
|
||||||
|
--selector=app=myapp
|
||||||
|
|
||||||
|
echo "Deployment completed successfully!"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Blue-Green Deployment
|
||||||
|
|
||||||
|
```bash
|
||||||
|

kubectl delete deployment/myapp-$NEW_VERSION -n $NAMESPACE
|

|
||||||
|
|
||||||
|
# Wait and monitor
|
||||||
|
sleep 60
|
||||||
|
|
||||||
|
# Delete old version
|
||||||
|
if [ "$CURRENT_SERVICE" != "" ]; then
|
||||||
|
kubectl delete deployment/myapp-$CURRENT_SERVICE -n $NAMESPACE
|
||||||
|
echo "Old version $CURRENT_SERVICE deleted"
|

|
||||||
|
|
||||||
|
echo "Blue-green deployment completed!"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Health Check Script
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
# health-check.sh
|
||||||
|
|
||||||
|
URL=$1
|
||||||
|
MAX_ATTEMPTS=30
|
||||||
|
SLEEP_TIME=10
|
||||||
|
|
||||||
|
for i in $(seq 1 $MAX_ATTEMPTS); do
|
||||||
|
echo "Attempt $i of $MAX_ATTEMPTS"
|
||||||
|
|
||||||
|
if curl -f -s $URL/health > /dev/null; then
|
||||||
|
echo "Health check passed!"
|
||||||
|
exit 0
|
||||||
|
fi
|
||||||
|
|
||||||
|
if [ $i -lt $MAX_ATTEMPTS ]; then
|
||||||
|
echo "Health check failed, retrying in $SLEEP_TIME seconds..."
|
||||||
|
sleep $SLEEP_TIME
|
||||||
|
fi
|
||||||
|
done
|
||||||
|
|
||||||
|
echo "Health check failed after $MAX_ATTEMPTS attempts"
|
||||||
|
exit 1
|
||||||
|
```
|
||||||
|
|
||||||
|
## Best Practices
|
||||||
|
|
||||||
|
### Security
|
||||||
|
- Use secrets management (never commit secrets)
|
||||||
|
- Enable RBAC in Kubernetes
|
||||||
|
- Use network policies to restrict traffic
|
||||||
|
- Scan images for vulnerabilities
|
||||||
|
- Run containers as non-root
|
||||||
|
- Use read-only root filesystem where possible
|
||||||
|
- Enable pod security policies
|
||||||
|
|
||||||
|
### Reliability
|
||||||
|
- Set appropriate resource limits
|
||||||
|
- Configure health checks (liveness, readiness)
|
||||||
|
- Use rolling updates with maxUnavailable: 0
|
||||||
|
- Implement circuit breakers
|
||||||
|
- Set up autoscaling
|
||||||
|
- Configure pod disruption budgets
|
||||||
|
- Use multiple replicas across zones
|
||||||
|
|
||||||
|
### Monitoring
|
||||||
|
- Set up logging (ELK, Loki, CloudWatch)
|
||||||
|
- Configure metrics (Prometheus, Datadog)
|
||||||
|
- Set up alerts for critical issues
|
||||||
|
- Use distributed tracing (Jaeger, Zipkin)
|
||||||
|
- Monitor resource usage
|
||||||
|
- Track deployment success/failure rates
|
||||||
|
|
||||||
|
### Performance
|
||||||
|
- Use CDN for static assets
|
||||||
|
- Enable caching where appropriate
|
||||||
|
- Optimize container images
|
||||||
|
- Use horizontal pod autoscaling
|
||||||
|
- Configure connection pooling
|
||||||
|
- Implement rate limiting
|
||||||
|
|
||||||
|

# Create Dockerfile Command
|
||||||
|
|
||||||
|
You are helping the user create an optimized Dockerfile for containerizing their application following Sngular's DevOps best practices.
|
||||||
|
|
||||||
|
## Instructions
|
||||||
|
|
||||||
|
1. **Detect application type**:
|
||||||
|
- Node.js (Express, Fastify, NestJS, Next.js)
|
||||||
|
- Python (FastAPI, Flask, Django)
|
||||||
|
- Go application
|
||||||
|
- Java/Spring Boot
|
||||||
|
- Static site (React, Vue, etc.)
|
||||||
|
- Multi-service application
|
||||||
|
|
||||||
|
2. **Determine build requirements**:
|
||||||
|
- Package manager (npm, yarn, pnpm, pip, go mod, maven, gradle)
|
||||||
|
- Build steps needed
|
||||||
|
- Dependencies to install
|
||||||
|
- Environment variables required
|
||||||
|
- Port to expose
|
||||||
|
|
||||||
|
3. **Ask for optimization preferences**:
|
||||||
|
- Multi-stage build (recommended)
|
||||||
|
- Base image preference (alpine, slim, distroless)
|
||||||
|
- Development vs production
|
||||||
|
- Build caching strategy
|
||||||
|
|
||||||
|
## Dockerfile Templates
|
||||||
|

## Best Practices
|
||||||
|
|
||||||
|
### Security
|
||||||
|
- Use specific version tags, not `latest`
|
||||||
|
- Run as non-root user
|
||||||
|
- Use minimal base images (alpine, slim, distroless)
|
||||||
|
- Scan images for vulnerabilities
|
||||||
|
- Don't include secrets in images
|
||||||
|
|
||||||
|
### Performance
|
||||||
|
- Use multi-stage builds to reduce image size
|
||||||
|
- Leverage build cache (COPY dependencies first)
|
||||||
|
- Combine RUN commands to reduce layers
|
||||||
|
- Use .dockerignore to exclude unnecessary files
|
||||||
|
|
||||||
|
### Optimization
|
||||||
|
```dockerfile
|
||||||
|
# Bad: Creates multiple layers
|
||||||
|
RUN apt-get update
|
||||||
|
RUN apt-get install -y curl
|
||||||
|
RUN apt-get install -y git
|
||||||
|
|
||||||
|
# Good: Single layer with cleanup
|
||||||
|
RUN apt-get update && apt-get install -y \
|
||||||
|
curl \
|
||||||
|
git \
|
||||||
|
&& rm -rf /var/lib/apt/lists/*
|
||||||
|
```
|
||||||
|
|
||||||
|
### Health Checks
|
||||||
|
```dockerfile
|
||||||
|
# Application health check
|
||||||
|
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
|
||||||
|
CMD curl -f http://localhost:3000/health || exit 1
|
||||||
|
```
|
||||||
|
|
||||||
|
### Build Arguments
|
||||||
|
```dockerfile
|
||||||
|
ARG NODE_VERSION=20
|
||||||
|
FROM node:${NODE_VERSION}-alpine
|
||||||
|
|
||||||
|
ARG BUILD_DATE
|
||||||
|
ARG VCS_REF
|
||||||
|
LABEL org.label-schema.build-date=$BUILD_DATE \
|
||||||
|
org.label-schema.vcs-ref=$VCS_REF
|
||||||
|
```
|
||||||
|
|
||||||
|
## Building and Running
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Build image
|
||||||
|
docker build -t myapp:latest .
|
||||||
|
|
||||||
|
# Build with build args
|
||||||
|
docker build --build-arg NODE_VERSION=20 -t myapp:latest .
|
||||||
|
|
||||||
|
# Run container
|
||||||
|
docker run -p 3000:3000 -e NODE_ENV=production myapp:latest
|
||||||
|
|
||||||
|
# Run with docker-compose
|
||||||
|
docker-compose up -d
|
||||||
|
|
||||||
|
# View logs
|
||||||
|
docker logs -f myapp
|
||||||
|
|
||||||
|
# Execute command in container
|
||||||
|
docker exec -it myapp sh
|
||||||
|
```
|
||||||
|
|
||||||
|
## Image Size Optimization
|
||||||
|
|
||||||
|
```dockerfile
|
||||||
|
# Use smaller base images
|
||||||
|
FROM node:20-alpine # ~110MB
|
||||||
|
# vs
|
||||||
|
FROM node:20 # ~900MB
|
||||||
|
|
||||||
|
# Use distroless for Go/static binaries
|
||||||
|
FROM gcr.io/distroless/static-debian11 # ~2MB
|
||||||
|
|
||||||
|
# Multi-stage builds
|
||||||
|
FROM node:20 AS builder
|
||||||
|
# ... build steps
|
||||||
|
FROM node:20-alpine AS production
|
||||||
|
COPY --from=builder /app/dist ./dist
|
||||||
|
```
|
||||||
|
|
||||||
|
Ask the user: "What type of application would you like to containerize?"
