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.
