resource.error: (1, 'Operation not permitted') when trying to run docker image

[rbrooklyn]

OS is Ubuntu 20.04.
Running on a Raspberry pi 4 4GB.

Unfortunately it seems the docker image is doing something docker or Ubuntu isn't allowing. When running sudo docker run -p 80:80 -p 8889:8889 kerberos/kerberos the following output is observed and the container stops:

Config files are available.
Config files are available.

hmmm @rbrooklyn do you have any update on this?

[rbrooklyn]

Only that it's probably still broken, unless an update has landed since I raised the issue.

The only way to get this working is to run the container privileged, which is obviously far from ideal.

I believe this is because the OS you are using.. maybe something have to change within the dockerfile. It works just fine on other OSes. Interested to get this working. Kind regards, Verstraeten Cédric

I had to run this using the --privileged flag to get this working on my RP4 running Ubuntu 20.04. I hope that helps.
