Docker hangs with dokku-logginer-supervisord installed

[rsteckler]

Fresh install of dokku v4.0.4, install this plugin, then deploy my app. Sometimes it works for a few pushes, then deployments/restarts hang and never work again.

A dokku --trace ps:restart shows that the deployment hangs on this line. Running the same command from the CLI also just hangs:

docker run -i -a stdin dokku/myapp:latest /bin/bash -c 'if [[ -L /exec ]];then rm -f /exec && cp -f /start /exec; fi'

I uninstalled the plugin and everything works again.

I'm by no means a docker expert so I'm not sure what's going on beyond that, but I'm happy to debug/test if anyone has ideas.

Thanks,
Ryan

After playing around with this for a while and reading about Docker for a few hours, I think you wanted run_in_container to use "docker run -d $APP ..."

Hi, I have been having the same issue.
@michaelshobbs do you have any hints about what's going on?

My app is getting stuck as well.

I couldn't debug anything by enabling trace or by running the command manually in bash.

I tried the change proposed in #33 and it worked perfectly!

@eljojo not sure what's happening here. I built a custom herokuish image that has supervisor installed already so my deployments bypass this execution path. if you run docker logs on the "hung" container, what do you see?

@sehrope abstracting run_in_container to always be interactive and attach stdin may not make sense here. in dokku, we only do this in dokku when we're piping something into the process.
