调研方向

Look at the svc-kasm/finish script that records session state on clean shutdown; it likely writes to a file or database. After an unclean shutdown, dockerd restarts session containers, and svc-kasm/run stops them. Examine the run script to see how it decides to stop containers and where session state is stored. The fix may involve detecting an unclean shutdown and reconciling container states with Kasm's records, possibly by checking Docker events or container labels. Test by reproducing the steps with docker kill and verifying sessions resume correctly.

Current Behavior

With #108 and #109, a clean stop brings the sessions back, because svc-kasm/finish records them. After an unclean shutdown (docker kill, power loss, OOM kill), finish does not run, so nothing is recorded: dockerd restarts the session containers and svc-kasm/run stops them again, as in #106. Kasm keeps showing them as running while their containers are Exited (2). For a running one, resume_kasm answers Session (901e0d37-3fff-4ab2-a039-9957718ad859) is in status (running) and cannot be resumed and get_kasm_status answers Kasm is not running.

$ docker exec kasm docker events --since 10m --until "$(date +%s)" --filter label=kasm.kasmid --format '{{.Action}} {{.Actor.Attributes.name}} {{.Actor.Attributes.signal}}'
start userkasm.loc_901e0d37 <no value>
start adminkasm.lo_b9e6c4c2 <no value>
kill adminkasm.lo_b9e6c4c2 15
kill userkasm.loc_901e0d37 15
stop adminkasm.lo_b9e6c4c2 <no value>
die adminkasm.lo_b9e6c4c2 <no value>
stop userkasm.loc_901e0d37 <no value>
die userkasm.loc_901e0d37 <no value>

Expected Behavior

Sessions come back in the state Kasm has them in after an unclean shutdown too.

Steps To Reproduce

On an image built from #109, launch a Workspace session.
docker kill kasm, then docker start kasm.
docker exec kasm docker ps -a --filter label=kasm.kasmid shows the session container Exited (2), while Kasm still has the session as running.
resume_kasm and get_kasm_status for it fail with the errors above.

Environment

- OS: Ubuntu 24.04.4 LTS (kernel 6.18, cgroup v1)
- How docker service was installed: docker-ce 29.3.1 from Docker's apt repository
- Workspace image: kasmweb/remmina:1.19.0-rolling-daily

CPU architecture

x86-64

Docker creation

docker run -d --name kasm --privileged --network host --stop-timeout 90 \
  -e KASM_PORT=443 \
  -v /path/to/kasm/data:/opt \
  kasm:pr-109
# kasm:pr-109 = lscr.io/linuxserver/kasm:1.19.0-ls150 with the root/ of #109 copied in
# plus HTTPS_PROXY and a CA bundle for the test VM's egress proxy
