Julien Calixte 0ac46ecadb docs: explain hardcoded host and Coolify network UUID

Coolify does not interpolate ${...} inside the labels: block, so the
two strings tying this template to its specific Coolify resource cannot
currently be variables. Document where they appear and how to swap
them when redeploying as a new resource.

CouchDB 3 on Coolify. The couchdb-init sidecar waits for the server to come up, creates the three system databases, and enables CORS via the config API — no file mounts required.

Deploy

In Coolify: New Resource → Docker Compose and point it at this repository.
In the resource's Environment Variables tab, set:
- COUCHDB_PASSWORD — required
- COUCHDB_USER — optional, defaults to admin
In the resource's Domains tab, assign a domain to the couchdb service on port 5984. Coolify fills SERVICE_FQDN_COUCHDB_5984 from this.
Deploy. couchdb-init runs once, exits, and won't restart.

Verify

Replace $DOMAIN and $PASS:

curl -fsS https://$DOMAIN/_up
curl -fsS -u admin:$PASS https://$DOMAIN/
curl -fsS -u admin:$PASS https://$DOMAIN/_all_dbs
curl -fsS -I -X OPTIONS https://$DOMAIN/ \
  -H "Origin: https://example.com" \
  -H "Access-Control-Request-Method: GET"

Expected: _up returns {"status":"ok",...}; / returns the CouchDB welcome JSON; _all_dbs returns ["_global_changes","_replicator","_users"]; the preflight returns 2xx with an Access-Control-Allow-Origin header.

If the init logs show CORS errors, you can re-trigger only that step by redeploying — the PUTs against /_node/_local/_config/... are idempotent.

CORS

Wildcard origin (*) with credentials = false — the only browser-spec-legal combination with a wildcard. For credentialed auth from the browser, edit the put_config cors origins/credentials lines in docker-compose.yml.

Hardcoded values (cloning to another Coolify resource)

Two strings in docker-compose.yml are pinned to this specific Coolify deployment and must be updated if you redeploy as a new resource:

The host in traefik.http.routers.coolcouch.rule=Host(couch.apoena.dev)
The per-resource Coolify network name, appearing twice: traefik.docker.network=lvw8efvnvsxduodrkg68zul3 and networks.coolify.name: lvw8efvnvsxduodrkg68zul3

They're hardcoded because Coolify does not interpolate ${...} inside the labels: block (it does inside environment: and networks.<name>.name:). The network UUID matches COOLIFY_RESOURCE_UUID for the resource — find it in Coolify's UI or in docker network ls after first deploy.

A sed swap before push, or a Coolify "Custom Build Command" running sed -i over the file, is the simplest way to keep this template portable.
