- Replace alternate template form (with {{YOUR_TAILSCALE_AUTHKEY}}, sys_module
cap, {{service-compose}} placeholder) with the canonical ts-TEMPLATE pattern:
Tailscale sidecar + Focalboard, both via network_mode namespace
- Use SQLite by default (Focalboard's stock behavior); Postgres mode
documented in README with config.json mount instructions
- Pin to mattermost/focalboard:7.11.4
- Add SECURITY.md and proper .gitignore (incl. focalboard/config.json
exclude so Postgres config files stay out of repo)
- Note: official Focalboard image is amd64-only; runs via emulation
on arm64 hosts (Apple Silicon)
- Verified: setup wizard renders, first-time account creation works
