The role's compose template names its service after the entity, which the rename turned into seaweedfs-console, while meta/volumes.yml still pointed the config mount at a role id that no longer exists and at the service key the engine consumer occupies. A mount whose service matches nothing is dropped without an error, so the console would have come up without its vhost config and still answered the HTTP probe from the nginx default page. The remaining files are line joins the formatter produced once the shorter symbol name let the calls fit on one line; their syntax trees are identical to the previous revision.

"""The CPU cap of one service, with a percentage resolved against the host.
|
|
|
|
``lookup('cpus', application_id[, service_name])`` reads
|
|
``services.<service_name>.cpus`` and resolves it through
|
|
:func:`plugins.filter.resource_filter.resolve_cpus`. A caller neither repeats
|
|
the resolution nor has to know that a percentage is read against the host's
|
|
raw core count rather than against the fair share, which is what every
|
|
consumer of a ``cpus`` value got wrong before this existed.
|
|
|
|
``service_name`` defaults to the role's entity name.
