[Feature Request] Add replacers/variables to ease configuration #66

Closed ThaDaVos closed 8 months ago

ThaDaVos commented 11 months ago

I am currently setting up a job-local to hourly restart a container (it's needed) - but to do that, I defined the labels on the container but I also had to fully type out the full container name in the command because as far as I know, there's no support for replacers/variables which are resolved to the targeted container - so, maybe this can be included? Or maybe a new job type for the usecase of interacting with a containers state, maybe like job-docker?

That's a good feature request.

This will get added to version 2.x in the works. I have been quite busy and being that this is an unpaid project, it's not of real high priority.

I don't have an exact timeline, but I think I should be able to get back to work on it within a couple weeks.

Am I right that job-local can't be set using labels on the target container?

ThaDaVos commented 11 months ago

I just checked, apparently job-local isn't supported through labels - but how does one even restart a docker container if there's not even docker inside the Chadburn container?

~Done it through CURL:~ ~curl --silent --unix-socket /var/run/docker.sock -X POST http://v1.43/containers/{CONTAINER_NAME_OR_ID}/restart~

Tried curl... not available...

The current version of Chadburn, like Ofelia, the project this one was forked from, uses a 3rd party library to talk to Docker over an API. The next big version when I can get to it, will remove this 3rd party library and talk directly to the Docker API.

There is no docker socket inside the local container.

Actually there is a docker.socket as you have to mount it for label support - so I hoped there was curl too as you can send commands to docker through curl - for now using a job-run with docker image to call docker commands
