services.builder picks the build strategy per service: auto detects from repo contents (Dockerfile → railpack → nixpacks), explicit overrides force a builder, and static builds assets in a node stage then serves them from an nginx image (static_build_cmd/static_dir, port 80 default). - cpu_reserve/memory_reserve → Docker CPU shares + MemoryReservation; cpu/memory stay hard caps (NanoCPUs/Memory). Empty string clears. - app_settings.default_cpu/default_memory override service-create fallbacks; capacity_policy=block fails deploys whose requested memory exceeds node capacity (default warn logs via slog). - Resource specs are validated — "512mb" fails instead of silently dropping the limit. - Fixes: deployments.go hardcoded nixpacks (auto-detect was dead code); DockerfileBuilder passed the Dockerfile *path* as build-context content; BuildImage never drained the daemon stream so builds could abort and errors went unseen — stream is now consumed and errorDetail surfaced. - CLI: --builder/--cpu-reserve/--memory-reserve/--static-cmd/--static-dir on create+update; MCP args on services create/update; UI Build & Resources card; OpenAPI + llms.txt + CLI.md. Verified live: static build of a real repo → nginx image → deployed; reserves reach HostConfig (shares=256, MemoryReservation=128Mi); validation rejects bad specs; builder persists + clears.

# Containr
|
|
|
|
> Self-hosted Docker PaaS — deploy and manage containerized apps, databases, cron jobs and preview environments. Operable by humans (web UI) and agents (API / CLI / MCP) through one contract.
|
|
|
|
Base URL: `https://<host>/api/v1`. OpenAPI: `docs/api/openapi.yaml`.
|
|
|
|
## Access (pick one)
|
|
|
|
- **API**: `Authorization: Bearer <pat>` — create a PAT in Settings → Access Tokens or `containr tokens create`. Scopes: `read` (GET/HEAD/OPTIONS only), `write` (everything but admin routes), `admin` (requires platform-admin owner).
|
|
- **CLI**: `containr auth login --api-url <url>` (or `--token cnp_…`), then e.g. `containr projects list --json`, `containr up`. Global flags: `--json`, `--yes`, `--profile`, `--idempotency-key`.
|
|
- **MCP**: run `containr-mcp` over stdio with `CONTAINR_API_URL` + `CONTAINR_TOKEN` env (or CLI profile). ~60 tools mirroring the API; destructive tools require `confirm: true`.
|
|
|
|
## Conventions
|
|
|
|
- **Errors**: `{"error": "msg", "code": "MACHINE_CODE"}`. Codes: `UNAUTHENTICATED`, `INVALID_TOKEN`, `FORBIDDEN`, `ADMIN_REQUIRED`, `SCOPE_INSUFFICIENT`, `NOT_FOUND`, `VALIDATION`, `CONFLICT`, `INTERNAL`, `DEPENDENCY_UNAVAILABLE`, `IDEMPOTENCY_IN_PROGRESS`, `NOT_CANCELLABLE`.
|
|
- **Idempotency**: send `Idempotency-Key: <uuid>` on POSTs — the first response replays for 24h; concurrent duplicates get 409. Always safe to send.
|
|
- **Pagination**: `?limit=` + `?cursor=` (pass `pagination.next_cursor` verbatim; legacy `?page=` also works). Invalid cursors fall back to page 1.
|
|
- **Deployments**: serialized per service — a deploy on a busy service returns `status: queued` and runs when the active one finishes. `POST /deployments/{id}/cancel` drops queued (`200 cancelled`) or aborts running (`202 cancelling`) work. `no_cache: true` on create disables the Docker layer cache. `PUT /services/{id}/variables` accepts `redeploy: true` to apply env changes to running containers.
|
|
- **Volumes**: service mounts via `PUT /services/{id}` `volumes: [{type: volume|bind, source, target, read_only}]` — replaces the whole list (`[]` clears), applied on next deploy. `GET /admin/volumes` inventories node volumes with `in_use` flags; `DELETE /admin/volumes/{name}` removes unused ones (admin).
|
|
- **Domains**: multiple hostnames per service via `GET|POST /services/{id}/domains`, `DELETE /services/{id}/domains/{domain_id}`, `POST …/{domain_id}/default` (mirrors `services.domain`). `GET /services/{id}/domains/check` returns `ok|wrong-target|pending` per domain vs `app_settings.public_ip`/`PUBLIC_IP`. `PUT` `maintenance_mode` redirects all traffic to `GET /maintenance` (needs `base_url`/`BASE_URL` setting); `basic_auth: [{username,password}]` stores bcrypt htpasswd and gates the route — responses return usernames only.
|
|
- **Builders & resources**: service field `builder` = `auto|railpack|nixpacks|dockerfile|static` (auto detects; static builds assets with `static_build_cmd` and serves `static_dir` via nginx:80). `cpu`/`memory` are hard caps; `cpu_reserve`/`memory_reserve` are soft reservations (CPU shares / MemoryReservation) — empty string clears. `app_settings.default_cpu`/`default_memory` set instance defaults; `app_settings.capacity_policy=block` rejects deploys exceeding node memory (default `warn`).
|
|
- **Identifiers**: all ids are UUIDs. Tokens: `cnp_` user PATs, `cagt_` agent onboarding tokens.
|

## Core objects
|
|
|
|
`projects` → `services` (git/app deploys) → `deployments`; plus `databases`, `templates`, `cron-jobs`, `variables`, `volumes`, `preview-environments`, `nodes`, `scaling`, `security`, `gateway`, `admin`, `notifications`, `user/tokens`.
