  2. Choose Deploy to continue.

  3. By default, the wizard will create a docker configuration overlay. This assigns the Docker::Host role to the nodes selected in the wizard.

  10. By default, the Docker wizard will save the deployment configuration in /root/cm‑docker‑setup.conf.

    This configuration file can be used to redeploy Docker in the future. Select OK to start the installation.
