CI/CD Implementation

Folder: .github/skills/tsh-implementing-ci-cd/ Used by: DevOps Engineer

Provides CI/CD pipeline design patterns and deployment strategies for GitHub Actions, GitLab CI, Bitbucket Pipelines, and other platforms.

Pipeline Design Principles

• Fail fast — Run linting and unit tests before expensive operations.
• Cache aggressively — Cache dependencies, Docker layers, and build artifacts.
• Parallelize — Run independent jobs concurrently to reduce total build time.
• Environment protection — Require approvals for production deployments.

Deployment Strategies

Strategy	When to Use
Blue/Green	Zero-downtime deployments with instant rollback capability
Canary	Gradual rollout to a subset of users for risk mitigation
Rolling	Sequential updates across instances with health checks
Feature flags	Decouple deployment from release for safe feature rollouts

Security

• Secrets referenced via environment variables, never hardcoded.
• Minimal permissions for deployment service accounts.
• Dependency scanning and vulnerability checks in pipeline.
