- Use npm ci only if package-lock.json exists
- Falls back to npm install if not present
- Allows flexible package installation without strict lockfile requirement
Changes:
- install.sh: user-template-next is now only built if USER_TEMPLATE_IMAGE=user-template-next:latest is set in .env
* Defaults to user-service-template (nginx) to save 4-5 minutes per install
* Dynamic build step counting based on configured templates
* Shows helpful message when template is skipped
* Build numbering adapts automatically ([1/3] vs [1/4])
- user-template-next/Dockerfile: Optimize build performance
* Pin Node version to 20.11-alpine for reproducibility
* Use npm ci instead of npm install for faster, reproducible builds
* Separate package.json copy for better layer caching
* Add --prefer-offline and --no-audit flags to npm ci
* Clean npm cache to reduce image size
* Add clear comments for multi-stage build steps
Impact:
- Default installations: 2-3 minutes faster
- Reduced build time for Next.js template (when enabled) via layer caching
- Better reproducibility and predictable builds
