- Read USER_TEMPLATE_IMAGES from .env to determine which templates to build
- Parse semicolon-separated template list and extract image names with tags
- Only build templates defined in .env, not all user-template-* directories
- Validate that template directories and Dockerfiles exist
- Warn when template is defined but directory/Dockerfile missing
- Warn about unused template directories not in USER_TEMPLATE_IMAGES
- Fallback to old logic (build all) when USER_TEMPLATE_IMAGES undefined
- Maintains backward compatibility with existing installations
- Improves .env.example with better documentation and examples
The install.sh script was only building user-template-next when
USER_TEMPLATE_IMAGE=user-template-next:latest was set in .env, which
was an old single-container configuration.
Changes:
- Remove dependency on USER_TEMPLATE_IMAGE for building user-template-next
- Always build user-template-next when directory exists
- Add user-template-next to TOTAL_BUILDS count automatically
- Change user-template-next build from optional warning to required
- Update build output to clearly show multi-container template building
- Update final installation summary to show template configuration
This ensures both dev and prod templates are always built for the
Multi-Container MVP, regardless of legacy .env settings.

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
- All build logs now written to spawner-install.log
- Added clear section headers for each build
- Replaced separate temp log files with single log file
- Added log file path hint at end of installation
