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

Upstream coverage (do not restate)

This skill wraps third-party products. Vendor mechanics are not restated here; fetch them from the source below. Where a row says "house subset stays in X", that file keeps only OrchestKit's threshold, config or ordering decision, not the vendor tutorial.
