Adding an admin member to a domain using rhc

Consider a situation where a new system administrator joins your team. As the new system admin is also responsible for making sure your production apps are running smoothly, you would like to add the new system admin as an administrator. You can do this by giving the new user an admin role.

Getting ready

To complete this recipe, you will need to have rhc installed on your machine. Please refer to the Installing the OpenShift rhc command-line client recipe in Chapter 1, Getting Started with OpenShift, for instructions.

You will need two OpenShift accounts to work through this recipe. Please refer to the Creating an OpenShift Online account recipe in Chapter 1, Getting Started with OpenShift, for OpenShift account registration instructions.

How to do it…

To add the openshift.cookbook.test@gmail.com user as an administrator to prodosbook of the command:

$ rhc add-member openshift.cookbook.test@gmail.com --namespace osbook --role admin

How it works…

The admin role allows a user to perform the following actions on a domain:

• Everything an editor can do such as performing actions related to applications
• Perform operations on a domain such as adding members to a domain

When you run the rhc add-member command with an admin role, OpenShift will add a new member to a domain with an admin role and then copy the public SSH key to the OpenShift gear ~/.ssh/authorized_keys file. This allows an editor to perform SSH-related operations.

To check whether the administrator has been added successfully, you can view the domain details by inserting the following command:

$ rhc domain-show

Domain prodosbook (owned by openshift.cookbook@gmail.com)
