"""Run container-structure-test without leaking Docker volumes.
|
|
|
|
container-structure-test starts one container per test and never removes it. The image
|
|
declares `VOLUME /data`, so every container drags an anonymous volume along that outlives
|
|
`docker rm`. With `--save` the containers are kept, and this wrapper removes the ones of
|
|
the image under test that the run created, together with their volumes (`remove(v=True)`);
|
|
containers of other images or of the compat suite (a parallel run, a compose stack) are left
|
|
alone.
|
|
Run with `task test:structure`.
|
|
|
|
Exit code: the one of container-structure-test.
