Red Hat OpenShift is an enterprise-ready Kubernetes platform that offers many powerful features that meet today's enterprise needs. For example, one feature of OpenShift is its flexible way of integrating with different authentication mechanisms, whether basic authentication, LDAP, Active Directory, OpenShift login, GitHub login, and so on.
As you start OpenShift the first time, you might find it super easy to leverage the
htpasswd utility, which is a built-in tool for most Linux distributions and macOS. This article demonstrates how you can create your own
htpasswd file and add it to Red Hat OpenShift through an intuitive web interface.

STEP 1: Create an htpasswd file
The command to create a new
htpasswd file is shown below:
htpasswd -c -B -b <file name to store HTPASSWD> <username> <password>
You have to replace file name to store HTPASSWD, username, and password values with your own values.
Once the file is created, you can omit the
-c option to simply append each username and password to the
STEP 2: Load htpasswd file from OpenShift
In your Red Hat OpenShift, log in as one of the users with a cluster-admin privilege. Please follow these steps:
- Click Administration on the left menu
- Select Cluster Settings
- Select the Global configuration tab
- Scroll down to select OAuth
- Select the HTPASSWD option
- Select the file
You should be able to find the
htpasswd converted to an OpenShift Secret under the openshift-config namespace.
Log out and verify you can login with the htpasswd option
Now, everything is set up. Just log out and find a new selection that indicates the
htpasswd login option.
