Operator cleared the swap and ruled out a docker-compose v1 shim. Ran
playbooks/upgrade-docker-ce.yaml: docker.io 20.10.24 -> docker-ce 29.8.0,
docker-compose 1.29.2 -> compose plugin v5.5.1, containerd 1.6.20 ->
containerd.io 2.3.5, buildx v0.37.1 added. 12 changed, 0 failed, verify
4/4. talk and beszel-agent back healthy on their restart policies.
The pre-state was worse than 'old': there was no cli-plugins directory, so
'docker compose' was not a command and exited 0 on a help blurb — a silent
no-op that reads as a successful deploy.
Records two things the run surfaced. vastblue-u5-pg and its anonymous
volume were removed when the old daemon stopped; the playbook has no rm,
prune or purge and five other containers survived, so the cause is almost
certainly --rm, unprovable now that the record is gone. It was measured
beforehand as zero user tables in every database, so nothing was lost. And
the playbook's restart loop runs as infra-ops and cannot read a root-owned
0600 stack .env, so it false-FAILs that stack.
Also notes that nh3-dev is the only host where /opt/docker/compose is
root-owned; the other four are lkraven. Created /opt/docker/compose/talk
as lkraven so tts-dev can move talk out of ~/talk. Normalising the parent
is left to the operator.
