running Rundeck on k8s platform

[Oladipupo B]

Hi All,

I'm new to rundeck. I'm having a hard time trying to get rundeck setup in a container after pulling the image. There are some permissions denied on creating temp files i.e

23 time="2018-11-09T16:18:44Z" level=error msg="createStageFileAndSync failed: create stage file failed: couldn't create tempfile: open /home/rundeck/etc/.framework.properties081339861: permission denied" prefix="remco[10]" resource=framework.properties.toml

Does anyone know where i'm doing something wrong ?

Hi Oladipupo,

It seems a problem of the image, anyway I leave you step by step how works for me.

1) Download the Rundeck image with:

$ docker pull rundeck/rundeck:3.0.8

2) Run the container with:

$ docker run --name some-rundeck -v data:/home/rundeck/server/data rundeck/rundeck:3.0.8

3) To access GUI in your browser put:

http://localhost:4440

Also you have more information here:

https://hub.docker.com/r/rundeck/rundeck/

And here you have a lot of options to play with Rundeck Docker image:

https://github.com/rundeck/docker-zoo

BR!

Thank you very much, I'll try the 3.0.8 version right now.

Hi Racuna,

Thanks again but I'm afraid I didn't get further. I've tried using 3.0.7 & 3.0.8 but both images are acting the same way. The logs show "Permission denied" on creating temp files.

Hi!

What linux distro do you use? And what Docker version?

Thanks!

Hello!

The first thing that comes to mind is a potential permission error due to volume mounts. Is anything being mounted or otherwise changed with "/home/rundeck/etc" that might cause the Rundeck user inside the container to not have permissions to create files at that location? Would you be able to post your kubernetes pod configuration?

It might be worth it as well to check out the examples in the Docker Zoo: https://github.com/rundeck/docker-zoo . There is even a kubernetes example that may provide some insight for you!

Cheers,

Hi Reiner,

I'm currently trying this on Origin....CentOS 7.5 with Docker 1.13.

hi Greg,

Thank you very much. I did see the docker-zoo example for kubernetes but this was that was the pro version. I don't have a license key so I want to try getting this working with the free version first.

In regards to the volume mounts, nothing is being mounted or changed with "/home/rundeck/etc"

Thank you,

Oladipupo

Did you happen to resolve this?  I'm facing the same issue as I try to get rundeck working on OpenShift.

It's possible that SELinux is interfering with Docker volume mounts; I've had to go through this with Fedora, which (like OpenShift, and I *think* like Centos) comes with SELinux enabled by default.  Have a look at https://www.projectatomic.io/blog/2015/06/using-volumes-with-docker-can-cause-problems-with-selinux/ for some hints on how to get around this.
