Using Ansible builder created strange permissions

[Maik Brauer]

Hello,

after doing an "ansible-builder build --tag ansible-runner-dev:latest" container will start building. But some stuff which I put inside the "execution-environment.yml" can't be installed, as for example the /tmp directory has strange permissions there:

-rw-r--r-- 1  501   20       94 Feb 19  2019 plugin.yaml
-rwx------ 1 root root      701 Mar  8 12:59 ks-script-sjkvb6c9
-rwx------ 1 root root      291 Mar  8 12:59 ks-script-igw1w8it
drwxr-xr-x 1  501   20     4096 Jun 20 00:11 .
dr-xr-xr-x 1 root root     4096 Jun 20 07:27 ..

So what is UserID 501 and GroupID 20 in this case?

Base-Images which are used are the following:
quay.io/ansible/ansible-runner   latest      bec0dc171168  7 weeks ago    816 MB
quay.io/ansible/ansible-builder  latest      b0348faa7f41  4 months ago   779 MB

All this leads in my case in a 

[3/3] STEP 17/20: RUN helm plugin install https://github.com/databus23/helm-diff
mktemp: failed to create directory via template '/tmp/helm-diff-XXXXXX': Permission denied

Any idea?

Thanks.
