# TEMPORARY mitigation (M1) for the unfiltered-prune incident
|
|
|
|
|
# (docs/incidents/2026-07-30-ollama-solaria-vanish.md §7). node-agent runs
|
|

# `docker container prune()` with NO filters every CHECK_INTERVAL, and the
|
|
|
|
|
# Docker API removes EVERY non-running container regardless of restart
|
|

|
|
# policy or compose labels — this already destroyed ollama@solaria. On VPS
|
|
|
|
|
# the loss is worse: humanai-mailer and humanai-landing have no compose

|

# definition in this repo, so a pruned container cannot be recreated.
