Deploy

Deploy the application to a target environment with pre/post checks.

Steps

1. Determine the target environment from the argument (staging, production, preview).
2. Run pre-deployment checks:
   • All tests pass: run the test suite.
   • No uncommitted changes: git status --porcelain.
   • Branch is up to date: git fetch && git status -uno.
   • Build succeeds: run the build command.
   • No critical vulnerabilities: run dependency audit.
3. Detect the deployment method:
   • Vercel/Netlify: vercel --prod or netlify deploy --prod.
   • Docker: Build image, push to registry, update deployment.
   • Kubernetes: Apply manifests with kubectl apply.
   • SSH: rsync build artifacts and restart service.
   • GitHub Pages: Push to gh-pages branch.
4. Execute the deployment:
   • Tag the deployment: git tag deploy-<env>-<timestamp>.
   • Run the deployment command.
   • Wait for health check confirmation.
5. Run post-deployment verification:
   • Hit the health endpoint and verify 200 response.
   • Run smoke tests if available.
   • Check error rates in monitoring if accessible.
6. Report deployment status with rollback instructions.

Format

Deployment: <environment>
Version: <git-sha-short>
Status: <success/failed>

Pre-checks:
  - [x] Tests passing
  - [x] Build successful
  - [x] No uncommitted changes

Deployed at: <timestamp>
URL: <deployment-url>
Health: <healthy/unhealthy>

Rollback: <rollback-command>

Rules

• Never deploy to production from a non-default branch without explicit confirmation.
• Always run pre-deployment checks; abort on any failure.
• Create a deployment tag for every production deployment.
• Include rollback instructions in every deployment output.
• Verify the health endpoint responds within 60 seconds after deployment.
