Chapter 6. Cluster Administrator Setup


Authentication

Set up the authentication using AllowAll Authentication method.

AllowAll Authentication
Set up an authentication model which allows all passwords. Edit /etc/origin/master/master-config.yaml on the OpenShift master and change the value of DenyAllPasswordIdentityProvider to AllowAllPasswordIdentityProvider. Then restart the OpenShift master.
  1. Now that the authentication model has been setup, login as a user, for example admin/admin:
    # oc login openshift master e.g. https://1.1.1.1:8443  --username=admin --password=admin
    Copy to Clipboard Toggle word wrap
  2. Grant the admin user account the cluster-admin role.
      # oc login -u system:admin -n default
      Logged into "https:// <<openshift_master_fqdn>>:8443" as "system:admin" using existing credentials.
    
      You have access to the following projects and can switch between them with 'oc project <projectname>':
    
      *default
       glusterfs
       infra-storage
       kube-public
       kube-system
       management-infra
       openshift
       openshift-infra
       openshift-logging
       openshift-node
       openshift-sdn
       openshift-web-console
    
      Using project "default".
    
      # oc adm policy add-cluster-role-to-user cluster-admin admin
      cluster role "cluster-admin" added: "admin"
