Hi @psychosis448. Thanks for your PR.

I'm waiting for a tektoncd 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Thanks for the PR @psychosis448, however this is not something we're going to merge.

PodSecurityPolicy was deprecated almost a year ago and will be removed from Kubernetes later this year.
From https://kubernetes.io/docs/concepts/policy/pod-security-policy/

PodSecurityPolicy is deprecated as of Kubernetes v1.21 and will be removed in v1.25

Also see the issue in tektoncd/pipeline discussing the deprecation tektoncd/pipeline#4112
and the corresponding PR tektoncd/pipeline#4122 which also discusses the plan to migrate to Pod Security Admission.

If patching the tekton-dashboard-tenant ClusterRole works for your use case I would suggest you continue doing that until the replacement approach is ready for use.
