Wraps the existing manually-run Vikunja instance on PIHA in the standard
service layout. No deploy — definition only, for review.
- services/vikunja/: docker-compose.yml (vikunja + postgres:16-alpine),
service.yaml, README, healthcheck, config.yml (OIDC, secret-free),
.env.example. Real .env stays gitignored.
- Pins EXISTING named volumes (vikunja_vikunja_db, vikunja_vikunja_files)
so DB + uploaded files survive cutover.
- extra_hosts forgejo.okit.pl=192.168.31.5 (npm on PIHA) so OIDC discovery
resolves over LAN instead of flaky public DNS.
- OIDC client secret injected via env (VIKUNJA_AUTH_OPENID_PROVIDERS_
FORGEJO_CLIENTSECRET); config.yml keeps trailing-slash authurl/redirecturl.
- Registers vikunja in hosts/piha/services.yaml + inventory/topology.yaml,
plus hosts/piha/runtime/vikunja override (advisory mem_limits).
