Chapter 2. Prerequisites

  • On RHEL Atomic Host, atomic is part of the OSTree and is ready to use.
  • On Red Hat Enterprise Linux, make sure you have covered the following:

    • Subscribe the system to the Extras channel which provides the atomic package.

For Red Hat Subscription Management run this command:

# subscription-manager repos --enable rhel-7-server-extras-rpms

If you are using Satellite, run:

# rhn-channel --add --channel rhel-x86_64-server-extras-7
  • Install atomic using Yum:
# yum install atomic
  • Make sure the docker service is running:
# systemctl status docker

If the output states "inactive", use the following command:

# systemctl start docker

On both systems, you need to have root privileges to use atomic.
