Container events are Ham Lab's own record, not Docker's short memory

Browse Source 
docker events is a live stream with a small in-memory backlog: ask for thirty days and you
get a few minutes, and a daemon restart loses the lot. That is why Dockhand kept its own
copy. A watcher now follows the stream and appends lifecycle events to a ring beside the
config, flushed every thirty seconds, so the question of what happened to a container last
week has an answer. Health-check exec events are excluded — three per probe, thousands a
day, and the health panel says it better.
