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

Strategy	Use Case	Risk
Rolling	Default, gradual replacement	Low - automatic rollback
Blue-Green	Instant switch, easy rollback	Medium - double resources
Canary	Progressive traffic shift	Low - gradual exposure

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

Container user	Non-root (uid 1001)	Security best practice, required by many orchestrators
Deployment strategy	Rolling update (default)	Zero downtime, automatic rollback, resource efficient
Secrets management	External Secrets Operator	Syncs from cloud providers, GitOps compatible
Health checks	Separate startup/liveness/readiness	Prevents premature traffic, enables graceful shutdown
