CI/CD & Deployment

When to use this skill

• Configuring GitHub Actions workflows.

• Setting up automated deployments.

• Configuring test runners in CI.

1. GitHub Actions

• Triggers: on: push for branches, on: pull_request for verification.

• Caching: Always cache dependencies (npm, pip, composer) to speed up builds.

• uses: actions/setup-node@v4 with: node-version: 18 cache: 'npm'

2. Deployment

• Atomic: Deployment should be atomic (zero downtime).

• Migration: Run DB migrations during deployment, but ensure backward compatibility.

• Secrets: Use repo secrets; never strict commit credentials.
