Remove kubeadmin

So it's time to remove your default kubeadmin account. For ease of use lets use htpasswd

Create users

Generate a htpasswd file for a few users

cd
touch htpasswd
htpasswd -Bb htpasswd andrew openshift
htpasswd -Bb htpasswd david openshift
htpasswd -Bb htpasswd karla openshift

oc create secret generic htpasswd --from-file=htpasswd -n openshift-config

 oc apply -f - <<EOF
apiVersion: config.openshift.io/v1
kind: OAuth
metadata:
  name: cluster
spec:
  identityProviders:
  - name: Local Password
    mappingMethod: claim
    type: HTPasswd
    htpasswd:
      fileData:
        name: htpasswd
EOF

Delete kubeadmin

Yes you should!

oc delete secret kubeadmin -n kube-system
