Changes:
- Reviewed all docker-compose files to identify required variables
- Updated all .env.example files to include ONLY variables used in their respective compose files
- Changed all placeholder values to empty strings for cleaner configuration
- Fixed variable name inconsistency: DOWNLOADS_DIR -> DOWNLOAD_DIR (to match main .env)
- Removed unnecessary variables that aren't used by the compose files
All .env.example files now:
- Contain only the variables actually used in the stack
- Have empty values instead of example placeholders
- Match the variable names used in docker-compose files
This ensures clean, minimal .env files for each stack without any extraneous variables or confusing placeholder values.
Major improvements to environment variable management:
1. Added .env.example files for ALL stacks
- Each stack now has its own .env.example with only required variables
- Variables include comments explaining their purpose
- Examples: core, dockge, infrastructure, dashboards, arcane, media, media-management, transcoders, monitoring, sablier, utilities, productivity, wikis, vpn, homeassistant, alternatives
2. Created .env.global generation
- Generates /opt/stacks/.env.global with all variables
- Strips comments and blank lines for clean output
- Available to all stacks for reference
3. Improved variable replacement strategy
- Variable replacement now ONLY targets labels and x-dockge sections in docker-compose files
- Configuration files (traefik, authelia) still get full variable replacement
- Uses Python script for precise section detection
- Preserves environment variables and volume mounts as-is
4. New deployment approach
- Each stack copies .env.example to .env
- Values populated from main ~/EZ-Homelab/.env file
- No more manual sed commands to remove unused variables
- Consistent approach across all deployment functions
5. Updated deployment functions
- deploy_dockge, deploy_core, deploy_infrastructure, deploy_dashboards, deploy_arcane, deploy_sablier_stack
- All now use process_stack_env() for clean .env handling
- All use updated localize_yml_file() for targeted variable replacement
Benefits:
- Clean, minimal .env files for each stack
- No unnecessary variables or comments in deployed .env files
- Variables in compose files preserved for Docker Compose to handle
- Easier to understand what each stack needs
- Uniform deployment approach across all stacks
- Added ARCANE_ENCRYPTION_KEY and ARCANE_JWT_SECRET to .env.example
- Created deploy_arcane() function in ez-homelab.sh
- Auto-generate Arcane secrets after Authelia secrets
- Deploy Arcane in both Option 2 (Core Server) and Option 3 (Additional Server)
- Added Arcane docker-compose.yml configuration
