Deployments

A deployment is a long-lived application instance ZopNight runs in your Kubernetes cluster. It lives inside an environment, is built from a connected git repository, and is rolled out through a Helm release that ZopNight manages on your behalf.

Which service serves which call

Since the catalog/runtime split (Phase 3a–3c, May 2026), ownership of the deployment surface is split across two services: config owns the long-lived catalog row, and deployer owns the per-deploy runtime (builds, revisions, events, Helm rollout). Both services sit behind the gateway at zopnight.com/api — the split is invisible to API clients, but the table below explains which service handles what, in case you're tracing logs or wiring fine-grained IAM.

Lifecycle

1. Client calls POST /deployments. Config writes the catalog row plus a revision-#1 placeholder, then enqueues a job into the deployer's MySQL jobs queue via deployer gRPC.
2. The deployer's worker pool claims the job, clones the repo, runs stack detection, and dispatches a GitHub Actions build.
3. On build completion, the deployer mints a per-deploy ephemeral kubeconfig from the cloud account credentials and applies a Helm release to the target namespace on the deployment's deployment space.
4. Every stage boundary appends an event to deployment_events (deployer). Status changes are written back to config via gRPC so the catalog row always reflects the live state.
5. Subsequent pushes (auto-deploy) or config changes create new revisions; the deployer reconciles them as rolling updates with zero downtime.
6. DELETE /deployments/{id} on config calls the deployer's inbound Teardown gRPC (idempotent — re-runs return already_clean=true) before soft-deleting the catalog row.

Create a Deployment

Two equivalent forms: a flat path for integrations and CI scripts, and an env-nested form for the canvas (which already has the environment in context). Both land on config.

curl -X POST https://zopnight.com/api/deployments \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "checkout",
    "envId": "env_abc",

    "repoUrl": "https://github.com/acme/checkout",

Update Configs

Env-var, secret, port, replica, and resource changes go through PATCH /deployments/{id}/configs on config. The deployer picks the new shape up on the next revision and applies it as a rolling update — the catalog stores configs as opaque JSON; the deployer parses the typed shape (port, replicas, liveness, resources, expose, rootPath) at apply time.

curl -X PATCH https://zopnight.com/api/deployments/dep_xyz/configs \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "configs": {
      "envVars": { "LOG_LEVEL": "debug" },
      "port": 8080
    }
  }'

Analyze a Deployment

Revisions

Every image or config change is captured as a revision. Revisions are immutable. Push-triggered revisions carry the GitHub delivery_id as their idempotency key (UUID v5 of the delivery), so webhook replays coalesce into a no-op via INSERT IGNORE — see Webhooks for the full dedup story.

curl -X POST https://zopnight.com/api/deployments/dep_xyz/revisions \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "image": "registry.zopnight.com/acme/checkout:v1.4.3",
    "buildID": "build_789",
    "note": "Hotfix for retry loop"
  }'

Rollback

curl -X POST https://zopnight.com/api/deployments/dep_xyz/rollback \
  -H "Authorization: Bearer <token>" \

LoadBalancer Status

For deployments that expose ports as http or tcp, ZopNight provisions a cloud LoadBalancer through the cluster's ingress class. The endpoint below is what the UI polls during the post-deploy "Waiting for public address…" state.

{
  "data": {
    "status": "ready",
    "address": "a-12345.elb.us-east-1.amazonaws.com",
    "ports": [
      { "port": 80,  "protocol": "HTTP" },
      { "port": 443, "protocol": "HTTPS" }
    ],
    "tls": { "issuer": "letsencrypt-prod", "expiresAt": "2026-07-29T00:00:00Z" }
  }
}
