Troubleshooting

Someone asked you for a 'docker-compose' snippet...How do you give them that?

If you are not using docker-compose, that can sound like a daunting task. Have no fear though, the following cli command spits it out.

1
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock:ro ghcr.io/red5d/docker-autocompose <container-name-or-id> [<additional-names-or-ids>]

Now you should upload this to logs.notifiarr.com after removing personal details and passwords.

Installation

Installing Docker, how and where?

I'd have a look at the official Docker Engine installation instructions.

Guides

I would like to execute my own scripts on startup, how would I do this?

This will only work for containers using s6 overlay, recognisable by ENVIRONMENT printed at the top of the log when the container starts.

If you have a need to do additional stuff when the container starts or stops, you can mount your script with the volume /docker/host/my-script.sh:/etc/cont-init.d/99-my-script to execute your script on container start or /docker/host/my-script.sh:/etc/cont-finish.d/99-my-script to execute it when the container stops. An example script can be seen below.

Got any Docker guides?

Take a look here for an extensive guide on best practises from the *arr team.

But, but, how do I configure all this stuff?

Maybe TRaSH from TRaSH Guides can help...
