NEW QUESTION # 13
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.
Answer:
Explanation:
See the solution below in Explanation.
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
* Verify:
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.
