Installing OpenSUSE Leap in a Docker container - no clue how to perform that

[Krzysztoff]

Hi,
I tried to install OpenSUSE Leap 15.5 using the Docker image from dockerhub (opensuse/leap:15.5), but I failed miserably :c

First of all, am I right in assuming that there’s no documentation regarding opensuse Docker images whatsoever? I wasn’t able to find one, no GitHub repos, no websites, no other forums. Nothing.

Secondly, I tried inspecting the image in order to find env variables that need to be provided while creating the container, but the ones that I found are… a bit enigmatic and I cannot make any sense out of them.

Anybody tried to install OpenSUSE as a Docker container before and can help with that?

I failed miserably

That is very precise, complete and technically correct description.

@Krzysztoff

env variables that need to be provided

What makes you think there are some?

@Krzysztoff

a bit enigmatic

Yes, you usually need to learn tools you are using.

docker pull opensuse/leap
docker container run -it opensuse/leap

Thanks for your help.

In the end I managed to run the leap image using a simple docker-compose file.

In case someone needs this in the future:

version: '3'

services:
  opensuse-leap:
    image: opensuse/leap
    stdin_open: true
    tty: true

I run them in a detached mode:

docker compose up -d

And then I can attach to a container using its id:

docker attach <container_id>

To detach without stopping the container use escape sequence:

<Ctrl-p><Ctrl-q>

The only concern (or a concept that I fail to understand) is that this container version seems… a bit different (stripped down) from “normal” version, meaning:
There’s no yast in terminal, even no ip command, no nano, no vi, no hostname command etc. I could go on with this list, but I hope you get what I’m trying to say.

Am I correct in assuming that I need to install these tools manually?

Yes. That is the whole point of containers. To have minimal environment to run one task.

[Krzysztoff]

Yup, that much I know.

Is there any way to run a full version of suse in a container? Or do I need to just use regular VMs?

[sfalken]

Distrobox will do basically what you’re asking.

If you want an interactive container that is basically “Leap in a container”

Define “full version”. You can install anything you want or miss.
