Task 1
Manage Identity Provider
Task information Details: Create the following HTPasswd users: bob, qwerty, john, armstrong, natasha, harry, susan. Create a secret from the HTPasswd file in openshift-config. Configure cluster OAuth to use the HTPasswd identity provider. Restart the OAuth pods so the new authentication configuration takes effect.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

Solution:
Create the initial HTPasswd file with the first user:
htpasswd -c -B -b /tmp/htpass.txt bob indionce
Add the remaining users:
htpasswd -b /tmp/htpass.txt qwerty catalog htpasswd -b /tmp/htpass.txt john john123
htpasswd -b /tmp/htpass.txt armstrong natasha123
htpasswd -b /tmp/htpass.txt natasha arthstrong htpasswd -b /tmp/htpass.txt harry harry123
htpasswd -b /tmp/htpass.txt susan susuan123
Create the secret in openshift-config:
oc create secret generic ex280-secure --from-file=htpasswd=/tmp/htpass.txt -n openshift-config
Edit OAuth and add the HTPasswd identity provider:
oc edit oauth cluster
Use a valid structure like this:
spec:
identityProviders:
- name: ex280-idp-secure mappingMethod: claim type: HTPasswd htpasswd:
fileData:
name: ex280-secure
Save and exit.
Restart OAuth pods:
oc delete pod -n openshift-authentication -l app=oauth-openshift

oc get pods -n openshift-authentication oc get oauth cluster -o yaml
This task validates OpenShift local authentication configuration through HTPasswd and cluster OAuth integration.

oc new-project apollo oc new-project test oc new-project demo
Grant cluster-admin to bob:
oc adm policy add-cluster-role-to-user cluster-admin bob
Disable normal self-provisioning for authenticated users:
oc adm policy remove-cluster-role-from-group self-provisioner system:authenticated:oauth
Allow john to self-provision:
oc adm policy add-cluster-role-to-user self-provisioner john
Give natasha view access in test and apollo:
oc policy add-role-to-user view natasha -n test oc policy add-role-to-user view natasha -n apollo
Give armstrong admin in apollo:
oc policy add-role-to-user admin armstrong -n apollo
Remove kubeadmin secret:
oc delete secret kubeadmin -n kube-system
Verify permissions:
oc adm policy who-can create projectrequests oc describe rolebinding.rbac -n apollo oc describe rolebinding.rbac -n test
