devops-deployment（开发运营部署）

DevOps & Deployment Skill

Comprehensive frameworks for CI/CD pipelines, containerization, deployment strategies, and infrastructure automation.

Note: If disableSkillShellExecution is enabled (CC 2.1.91), the Docker install check won't run. Verify Docker is available for container operations: docker --version.

Overview

• Setting up CI/CD pipelines
• Containerizing applications
• Deploying to Kubernetes or cloud platforms
• Implementing GitOps workflows
• Managing infrastructure as code
• Planning release strategies

Key Concepts

CI/CD Pipeline Stages

1. Lint & Type Check - Code quality gates
2. Unit Tests - Test coverage with reporting
3. Security Scan - npm audit + Trivy vulnerability scanner
4. Build & Push - Docker image to container registry
5. Deploy Staging - Environment-gated deployment
6. Deploy Production - Manual approval or automated

Container Best Practices

Multi-stage builds minimize image size:

• Stage 1: Install production dependencies only
• Stage 2: Build application with dev dependencies
• Stage 3: Production runtime with minimal footprint

Security hardening:

• Non-root user (uid 1001)
• Read-only filesystem where possible
• Health checks for orchestrator integration

Kubernetes Deployment

Essential manifests:

• Deployment with rolling update strategy
• Service for internal routing
• Ingress for external access with TLS
• HorizontalPodAutoscaler for scaling

Security context:

• runAsNonRoot: true
• allowPrivilegeEscalation: false
• readOnlyRootFilesystem: true
• Drop all capabilities

Deployment Strategies

Rolling Update (Kubernetes default):

strategy:
  type: RollingUpdate
  rollingUpdate:
    maxSurge: 25%
    maxUnavailable: 0  # Zero downtime

Secrets Management

Use External Secrets Operator to sync from cloud providers:

• AWS Secrets Manager
• HashiCorp Vault
• Azure Key Vault
• GCP Secret Manager
