Editing configurations of a remote Docker host

You can edit the host name or the port of the registered Docker host system instead of registering it as a new remote host if any of the parameters are changed on the remote host system. You can also change the mode of authentication of a registered remote Docker host.

You must have completed the following tasks:
  1. Set up the remote Docker host system. See Setting up a remote Docker host system or Setting up a secure remote Docker host system.
  2. Registered the remote Docker host with IBM® Rational® Test Automation Server. See Registering a remote Docker host with IBM Rational Test Automation Server.

      Note: You must have generated the .pem files on the remote host system and copied the files to your local drive.
    • To change from a secure mode to a non-secure mode, clear the Secure mode option.
  6. Click Test connection to test whether a connection is established between Rational® Test Automation Server and the remote host system:
