Active toolbox sessions prevent systemd shutdown #993

Open djrenren opened 2 years ago

djrenren commented 2 years ago

Describe the bug If you have an active toolbox session and you try to reboot the host machine, the container will refuse to shutdown. Eventually it will timeout and systemd will forcibly kill the process.

Steps how to reproduce the behavior

  1. Enter any toolbox with toolbox enter my-container
  2. Trigger a shutdown from the host machine. (On gnome I click the top-right menu -> Power Off / Log out -> Power Off...)
  3. "A stop job is running..." from systemd

Expected behaviour The container should gracefully shutdown and shutdown should work.

Actual behaviour Wait for systemd to SIGKILL the container process.

Additional context I can reproduce the issue using either of these images:

➜  ~ podman images
REPOSITORY                                       TAG         IMAGE ID      CREATED       SIZE

I've been experiencing this issue for years, finally had some inspiration to do something about it:

cat << EOF > ~/.config/systemd/user/stop-toolbox-containers.service
[Unit]
Description=Stop all Toolbox containers on shutdown

[Service]
ExecStop=/usr/bin/podman stop --all --filter "label=com.github.containers.toolbox=true"
Type=oneshot
RemainAfterExit=yes

[Install]
WantedBy=default.target
EOF

systemctl --user daemon-reload
systemctl --user enable --now stop-toolbox-containers.service

I do think this should be properly handled by the toolbx itself. Maybe whatever is preventing containers from stopping can be fixed or this service can be incorporated into the toolbox package. @debarshiray what do you think?
