Deleting an app

cubeship app delete shop/api --yes

Or Danger on the app's settings, which asks for the app's name.

What goes

The app's containers, on every machine it runs on, stopped and removed first; then the app, its domains, its variables and its attachments. The proxy drops its names the moment the rows go.

The order — containers, then rows — is deliberate, and outside the transaction, because Docker has no rollback. A failure halfway leaves the containers gone and the app still listed, which a second delete finishes; the reverse would leave a container running with nothing naming it.

What stays

• Its images, in the instance's registry. Deleting a tag there unlinks a manifest and leaves the layers; Reclaim disk on the registry's page is the pass that frees space.
• The build cache, for an app that built. Nothing prunes it.
• A database it was attached to. Deleting an app detaches it and touches no data.

Deleting the level above

Deleting an environment takes every app in it; deleting a project takes its environments and their apps. Each asks for the thing's own name. The one refusal is production: it is created with its project and goes when the project does, never before.

Taking an app down without deleting it

Delete its live deployment. The container is stopped and removed, the app goes to down, and everything around it stays — domains, variables, attachments — coming back on the next deploy. See Deploys.
