Hi @elegos. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

We don't want to use a privileged container for this, better to label the file with the selinux context (:Z)

[elegos]

@afbjorklund as far as I've understood labelling via :Z will label the file in the host, which I'm pretty sure we don't want to mess with. Adding --security-opt label=disable won't pass the flags inside the container, avoiding any file tampering on the host.

Sounds reasonable, I typically don't have SELinux enabled myself
