I am trying to setup DEX in my kubernetes clusters and for that I want to configure API server with following flags. How can I achieve that?
--oidc-issuer-url=https://dex.example.com:32000 --oidc-client-id=example-app --oidc-ca-file=/etc/ssl/certs/openid-ca.pem --oidc-username-claim=email --oidc-groups-claim=groups
Also, I cannot find any file called kube-apiserver.yaml in /etc/kubernetes/manifests/kube-apiserver.yaml where I can add these flags and restart api-server.
If there is a way to this using kubeadm, please post specific example.

Note that if you are using the DigitalOcean Managed Kubernetes service, you would not have access to the control plane node as it is managed by DigitalOcean.
If you want to have full access to your Kubernetes cluster, you could install Kubernetes on a few Droplets and handle the management yourself:
