Expose container stop options

[jamesmr89]

It would be desirable to have these options configurable.

--stop-grace-period |   | Time to wait before force killing a container (ns|us|ms|s|m|h)
--stop-signal |   | API 1.28+ Signal to stop the container

https://docs.docker.com/edge/engine/reference/commandline/service_update/

Speaking of the API, Docker's API supports grace period to be supplied in the query but I wasn't able to find a way to specify a signal to send to the container, although it's possible to predefine desired stop signal when creating a container.

[G07cha]

Another option will be to handle stopping of the container by ourselves because it's possible to pass a signal through ContainerKill call but it obviously doesn't support any kind of delay.

You have two things :

At container creation, you can specify :

--stop-signal | SIGTERM | Signal to stop a container
--stop-timeout |   | API 1.25+ Timeout (in seconds) to stop a container

This is store in container config like other runtime options
API equivalent are :
https://docs.docker.com/engine/api/v1.30/#operation/ContainerCreate

StopSignal
StopTimeout

At container stop action, you can ovveride the default timeout to wait before killing it
That's what you saw in API

[WTFKr0]

And you have equivalent behavior for services, tho this issue is about swarm mode services :D

[G07cha]

@WTFKr0, yeah but we're not able to define stop signal dynamically and preserve timeout at the same time

I'm working on a PR for this but curious where in the UI others thing this should exist.

I feel like in the update config of services perhaps? (For service context). What about container config?

Here's what I have right now, not sure if this makes the most sense or not for services page:

It would be nice if this could be specified during container creation so that the delay and signal are respected from the UI [Stop] button. Sometimes I don't wish to do an automatic update and just wish to stop my container so I can inspect it's files without it running, however I need it to exit gracefully so that files are flushed.

Oh hey its me there from the past.

@jamesmr89 Did you ever get anywhere with the PR you were preparing?

[r7l]

Is there any news with this?

[deviantony]

No ETA on this, we'd accept a contribution.

[Commifreak]

Any updates on this? Is there no option to set a global default stop timeout which will be sent over to the API for stopping actions?
