    ./installMega.sh prepare_environment
  4. Run ./installMega.sh prepare_environment and then reboot all hosts to complete Podman installation. After reboot, run docker --version to verify the installation. The command returns the version of Podman. To check if Podman is installed correctly, run docker info.
  5. To enable FIPS mode, go to /home/mega/S84/mega/deployment_manager/DM_Helper_scripts and run ./installMega.sh enable_fips.

    Best practice is to enable FIPS mode while installing the OS. For more information, see the Installing the operating system section.
