2.7. Troubleshooting OAuth API events
In some cases the API server returns an unexpected condition error message that is difficult to debug without direct access to the API master log. The underlying reason for the error is purposely obscured in order to avoid providing an unauthenticated user with information about the server’s state.
A subset of these errors is related to service account OAuth configuration issues. These issues are captured in events that can be viewed by non-administrator users. When encountering an unexpected condition server error during OAuth, run oc get events to view these events under ServiceAccount.
The following example warns of a service account that is missing a proper OAuth redirect URI:
$ oc get events | grep ServiceAccount
Example output
1m 1m 1 proxy ServiceAccount Warning NoSAOAuthRedirectURIs service-account-oauth-client-getter system:serviceaccount:myproject:proxy has no redirectURIs; set serviceaccounts.openshift.io/oauth-redirecturi.<some-value>=<redirect> or create a dynamic URI using serviceaccounts.openshift.io/oauth-redirectreference.<some-value>=<reference>
Running oc describe sa/<service_account_name> reports any OAuth events associated with the given service account name.
$ oc describe sa/proxy | grep -A5 Events
Example output
Events: FirstSeen LastSeen Count From SubObjectPath Type Reason Message --------- -------- ----- ---- ------------- -------- ------ ------- 3m 3m 1 service-account-oauth-client-getter Warning NoSAOAuthRedirectURIs system:serviceaccount:myproject:proxy has no redirectURIs; set serviceaccounts.openshift.io/oauth-redirecturi.<some-value>=<redirect> or create a dynamic URI using serviceaccounts.openshift.io/oauth-redirectreference.<some-value>=<reference>
The following is a list of the possible event errors:
