Pod specifying runAsUser: 0 not working

[caesar0301]

Accoding to kubernetes bug fix https://github.com/kubernetes/kubernetes/issues/78308, pods that explicitly specifying runAsUser: <uid> or runAsGroup: <gid> should start the container always in every launch using given user or group. If runAsUser or runAsGroup is not set, the container should run with USER specified when building the image.

Now we get the sdk implementation that runAsUser: 0 is ignored when the user forces to launch the container with root, overwriting default image USER. The same to runAsGroup: 0.

https://github.com/kubernetes-client/c/blob/859fc3f5eecda59f4eea6b07431aa2ebf38db779/kubernetes/model/v1_security_context.c#L134

I have a local fix to remain the semantics meaning to introduce the invalid user and group as -1:

This issue is similar to https://github.com/kubernetes-client/c/issues/158. If we always pass "0" to API server, the default value in Kubernetes will be broken (that might introduce the issue https://github.com/kubernetes-client/c/issues/170)

It seems the best solution would be to replace int run_as_user with int *run_as_user, but this will bing great changes to openapi-generator/c template. https://github.com/kubernetes-client/c/pull/160#issuecomment-1332782208 The second solution is to introduce a magic number just like you did. https://github.com/kubernetes-client/c/pull/160#issuecomment-1331611270

I'm thinking of a better solution. What do you recommend?
