Solution

  • The key to your problem was updating PSP.

    I would like to add something about PSP:

    According to this documentation and this blog:

    As of Kubernetes version 1.21, PodSecurityPolicy (beta) is deprecated. The Kubernetes project aims to shut the feature down in version 1.25.

    However I haven't found any information in Rancher's case (the documentation is up to date).

    Rancher ships with two default Pod Security Policies (PSPs): the restricted and unrestricted policies.
