New 'image' lookup is the SPOT for resolving <registry>/<image>:<version> (swarm registry prefix in swarm mode, bare in compose; custom= accepts a string base for a second distinct custom image inside one app). container_image becomes a thin wrapper that forwards terms+kwargs and adds the compose image: "<ref>" line, so all existing template call sites keep their output byte-identical. The lookup-usage integration test now counts lookup_loader.get() delegation as production usage. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

"""Lookup `container_image`: compose ``image: "<ref>"`` line for a
|
|
container service.
|
|
|
|
Thin wrapper around the `image` lookup (the SPOT for resolving the
|
|
``<registry>/<image>:<version>`` reference). ``container_image`` only adds
|
|
the ``image: "..."`` compose-line wrapping so templates can drop it in as
|
|
a standalone statement:
|
|
|
|
# roles/web-app-X/templates/compose.yml.j2
|
|
{{ lookup('container_image', application_id, 'x') }}
|
|
|
|
# Locally-built image (no registry upstream).
|
|
{{ lookup('container_image', application_id, 'x', custom=True) }}
|
|
|
|
All resolution kwargs (``image=``, ``version=``, ``custom=``, ``tag_only=``)
|
|
are forwarded to `image`. For a bare reference (no wrapping), call the
|
|
`image` lookup directly.
|
|
|
|
Both terms (application_id, service_key) are required; they are validated
|
|
by `image`.
