An unmounted VOLUME does not fail: docker creates an anonymous volume for
it, the container works, and the gap shows up later as a volume nobody can
attribute. sys-ctl-hlth-volumes fails the deploy over exactly that, and its
whitelist keys on volume ids, which are new on every deploy, so the gap
cannot be suppressed there either. e0b973f9bb fixed one such case in
web-svc-xmpp by hand; this is the check that would have found it.
Attribution is the whole difficulty. meta/services.yml declares an image
under a key, and the compose file often runs it under another name:
web-app-jitsi declares the image under 'jitsi' and renders the service as
'web', web-app-erpnext runs one image as seven services, and the two RDBMS
consumer keys name no service of their own because the container comes from
sys-svc-rdbms. The sweep therefore unions the entry key with its
proxy.service_key and delegates the RDBMS keys to their provider role. A
first version keyed on the entry alone and reported six roles that mount
every path correctly, web-svc-xmpp among them.
Reading a config blob section is now its own module beside the registry
client, because the two readers were the same walk twice and registry.py
sat three lines under the file-size cap.
