Azure Container Apps Enable Dapr Sidecar

arazzo: 1.0.1

  title: Azure Container Apps Enable Dapr Sidecar
  summary: Enable the Dapr sidecar on a container app, wait for the new revision to provision, then list revisions.
  description: >-
    Dapr is configured per app through the app configuration block rather than as
    a standalone resource in this API surface. This workflow reads a container
    app, patches its configuration to enable the Dapr sidecar with an app id and
    protocol, polls the app until the resulting revision settles, then lists
    revisions to expose the Dapr-enabled revision. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

    Adaptation note: the spec has no dedicated Dapr component resource, so Dapr is
    enabled through the container app's configuration.dapr block, which is the
    field the underlying schema actually exposes.
