GATE 1 refuses to ladder an app that cannot prove a rung landed, and
only mastodon, nextcloud and stalwart could. None of those are installed
here, so the stepped upgrade — button or automatic — was unreachable for
every app on the box.
Three fixes.
_updaterPrimaryContainer assumed the container is "<app>-service". It is
a convention, not a rule: matrix names its anchor service matrix-synapse
and stoat names its api (container stoat-api). The verifier therefore
inspected a container that does not exist, saw no state, and could only
time out — on exactly the stateful apps that most need verifying. It now
reads the anchor service's container_name from the compose, buffering
per service block because container_name may sit either side of the
image line.
Added updaterVerifyHttpVersion: poll the app over its PUBLISHED port
from the host, pull the version from a JSON field or a response header,
and require agreement three polls running. Probed from the host rather
than `docker exec … curl` because half these images ship no curl at all
(mattermost is one), so exec-based probing is a coin flip on the
vendor's base image. Version comparison matches only the components both
sides state, since tags and self-reported builds rarely share precision:
v1.158.0 vs 1.158.0, 11.9 vs 11.9.1, 8.7.0 vs 8.7 all agree; 11.9 vs
11.10 does not.
Each app hook is then three facts. Verified live: all three confirm at
the version they are actually on, and all three REFUSE a version they
are not — which is the property that makes stepping them safe.
updaterUpgradeAuto now skips apps with no verifier instead of queueing a
task that GATE 1 will reject, which would otherwise mean a failure
notification every day for an app that was never eligible.
