Deploying and rollbacks

Every write that moves an app between states.

Mutations

createApp makes the app. redeploy re-runs its build and release from the current source. stopApp takes it down without deleting it.

rollbackDeployment(deploymentId) re-runs the image that build already produced, no rebuild. Ask Deployment.canRollback first: only the code goes back, variables, domains, storage and limits stay current. setAppRollbackKeep(id, count) sets how many past deployments stay rollback-eligible, 0 to 20, needs configure_apps.

Subscription

appStatus(slug) is a Server-Sent-Events stream, via graphql-yoga: it emits the app on every state change (an initial snapshot, then live), so a client tracks provisioning, start, stop and deploy with no polling.

Example

Redeploy an app:

mutation {
  redeploy(appId: "prj_123") {
    id
    status
  }
}
