dvcrn xCloud Docker Deploy
Adapt any docker-compose.yml to work with xCloud — a git-push Docker deployment platform.
How xCloud Works
git push → xCloud runs: docker-compose pull && docker-compose up -d
xCloud never runs docker build. Images must be pre-built in a public registry. SSL, reverse proxy, and domain routing are handled by xCloud — your stack must not duplicate them.
Read references/xcloud-constraints.md for the full ruleset before making changes.
Phase 0 — Detect Project Type First
Before anything else, scan the project directory for these files:
Read DETECT.md for full detection rules. Quick routing:
| Found in project | Stack | Action |
|---|---|---|
wp-config.php or wp-content/ |
WordPress | Read references/xcloud-native-wordpress.md |
composer.json + artisan |
Laravel | Read references/xcloud-native-laravel.md |
package.json + next.config.* |
Next.js | Docker path → use dockerfiles/nextjs.Dockerfile + compose-templates/nextjs-postgres.yml |
package.json (no framework config) |
Node.js | Read references/xcloud-native-nodejs.md |
composer.json (no artisan) |
PHP | Read references/xcloud-native-php.md |
requirements.txt or pyproject.toml |
Python | Docker path → use dockerfiles/python-fastapi.Dockerfile |
go.mod |
Go | Docker path — generate Dockerfile manually |
docker-compose.yml exists |
Existing Docker | Proceed to Step 1 below |
Dockerfile (no compose) |
Build-from-source | Generate compose → Scenario A below |
See references/xcloud-deploy-paths.md for the Native vs Docker decision guide.
Step 1 — Detect Which Scenarios Apply
Inspect the provided docker-compose.yml:
| Signal | Scenario |
|---|---|
build: or build: context: . |
A — Build-from-source |
| Caddy / Traefik / nginx-proxy service | B — Proxy conflict |
Multiple ports: across services |
B — Multi-port |
./nginx.conf:/etc/nginx/... volume mount |
B — External config |
Multiple services each with build: |
C — Multi-service build |
image: some-public-image, single port |
Already compatible — verify port + env vars |
A compose file can trigger multiple scenarios simultaneously (handle A first, then B).
Scenario A — Build-from-Source
Read
references/scenario-build-source.mdfor full details.
What to do:
- Remove
build:directive from compose - Replace
image:withghcr.io/OWNER/REPO:latest - Generate
.github/workflows/docker-build.ymlusingassets/github-actions-build.ymltemplate - Generate
.env.examplefrom all${VAR}references
Deliverables:
- Modified
docker-compose.yml .github/workflows/docker-build.yml.env.example- xCloud Deploy Steps (see Output Format)
Scenario B — Proxy Conflict / Multi-Port / External Config
Read
references/scenario-proxy-conflict.mdfor full details.
What to do:
- Remove Caddy/Traefik/nginx-proxy service entirely
- Remove SSL labels and multi-port
ports:from app services (replace withexpose:) - Add
nginx-routerservice with inline config viaconfigs:block - Expose single port (default:
3080) for xCloud to proxy
Deliverables:
- Modified
docker-compose.ymlwithnginx-router+configs:block .env.example- xCloud Deploy Steps
Scenario C — Multi-Service Build
Read
references/scenario-multi-service-build.mdfor full details.
When multiple services have build: directives (separate frontend + backend + worker):
What to do:
- For each service with
build:, create a separate GHCR image path - Generate a matrix GitHub Actions workflow that builds all images in parallel
- Update compose to use all GHCR image references
Deliverables:
- Modified
docker-compose.yml(allbuild:removed) .github/workflows/docker-build.yml(matrix strategy).env.example
Output Format
Always produce complete, copy-paste-ready output:
## Modified docker-compose.yml
[full file]
## .github/workflows/docker-build.yml (Scenario A/C only)
[full file]
## .env.example
[full file]
## xCloud Deploy Steps
1. Push repo to GitHub
2. (Scenario A/C) Wait for GitHub Actions to build image — check Actions tab
3. Server → New Site → Custom Docker → connect repo
4. Exposed port: [PORT]
5. Env vars to add: [list from .env.example]
6. Deploy
Rules
- Never include
build:in the final compose — xCloud silently ignores it - Never expose database ports to host (remove
"5432:5432"— useexpose:internally) - Never include Caddy, Traefik, nginx-proxy, or Let's Encrypt config
- Always preserve
environment:,volumes:,healthcheck:, worker/sidecar services - Always use
expose:(internal) notports:(host) for services behind nginx-router - WebSockets? Add upgrade headers to nginx config (see proxy-conflict reference)
configs.content:inline syntax requires Docker Compose v2.23+ — use heredoccommand:alternative if uncertain
