Please check https://github.com/dexidp/dex/blob/master/examples/k8s/dex.yaml, why the tests are failing and whether 2 replicas would also work.

[juliusvonkohout]

Thank you for the PR. Please check also whether https://github.com/danish9039/manifests/blob/sync/dex-next/common/dex/base/crds.yaml should be updated. And adjust the script to do so if needed.

[juliusvonkohout]

Please also rebase to master, the new copilot instructions should block pr titles that say sync instead of synchronisation

@juliusvonkohout I checked the Dex v2.45.0 failure locally,

first blocking issue was not replicas. The new Dex imagev2.45.0 now runs as named user dex:dex, while our deployment keeps runAsNonRoot: true without a numeric UID/GID. Kubernetes then rejects the pod with CreateContainerConfigError because it cannot verify that the named image user is non-root, so i have added numeric runAsUser: 1001 and runAsGroup: 1001 , and the Dex login flow passed
