OpenShift compatibility (RunAsUser)

[criztovyl]

When using ktunnel with OpenShift, for me ktunnel expose does not reliably work because the Deployment created has RunAsUser, which OCP does not allow unless you adjust it's security configuration.

OpenShift runs containers with non-root user by default, and the Deployment works fine when I manually remove the RunAsUser.

So far the bug, I am open to providing a PR, but maybe you already have a solution in mind?

containerUid is hardcoded set to 1000 so that the container runs as non-root

A simple way to run the container as non-root, but without running into this issue, would be to specify the non-root user via Dockerfile and not via "RunAsUser"
e.g. like this
