  title: Azure Container Apps Update App and List Revisions
  summary: Roll out a new image to a container app, wait for provisioning, then list the resulting revisions.
  description: >-
    Updating a container app's template produces a new revision. This workflow
    patches a container app with a new image and revision suffix, polls the app
    until provisioning settles, then lists the app's revisions so the new
    revision can be inspected. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
