bvandeusenandClaude Opus 5.5	1ba4784fa6	fix(maintenance): check first, drain before a Docker upgrade, wait 5 min after a drain, see containers back (#6098) ... On 2026-10-18 an update on VDNT-Docker02 restarted the Docker daemon six seconds in, before the drain that came only with the reboot, and every container on the node stopped. Docker's own packages restart the daemon from their install scripts; needrestart's list-only mode doesn't stop that. - The helper gains a `check` action (agent 1.24.0): a dry run of the update for each package manager, whether Docker is among it, and the running containers outside the swarm with their restart policies. - A swarm node is drained before an update that upgrades Docker, else only before a reboot, and at most once a job. - After a drain the job settles 5 minutes before the update or reboot. - Once the work is over, the containers that ran outside the swarm must be seen running again within 10 minutes, or the job fails naming them. - An older agent gets no check and its job runs as before.

bvandeusenandClaude Opus 5.5	200384e52d	feat(host_agent): a group's updates and reboots on a weekly cadence, one host at a time (#5768) ... #5768 "A maintenance cadence: a group's updates and reboots, one host at a time, on a schedule". A plan names an inventory group, a weekday and time in a time zone, a window and a reboot policy (only when required by default). At its slot a run takes the group's hosts in order and gives each a #5767 maintenance job. The next host starts only when the last is back in service: its agent is posting and, for a swarm node, the node is active and every replicated service is at its replicas. A failure stops the run, and no host is started once the window has passed. A host's latest failure shows as host_agent/<host>/maintenance_failed, for an ordinary alert rule. The page is Hosts → Maintenance. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-14 18:59:07 -04:00
