2.2.1 Yum or ULN Channel Subscription

To install all of the required packages to use Kubernetes, you must ensure that you are subscribed to the correct yum repositories or Unbreakable Linux Network (ULN) channels.

If your systems are registered with ULN, enable the ol7_x86_64_addons channel.

If you use the Oracle Linux yum server, enable the ol7_addons repository on each system in your deployment. You can do this easily using yum-config-manager:

# yum-config-manager --enable ol7_addons

For more information on the ol7_x86_64_addons channel, please see Oracle® Linux: Unbreakable Linux Network User's Guide for Oracle Linux 6 and Oracle Linux 7.

Important

Oracle does not support Kubernetes on systems where the ol7_preview, ol7_developer or ol7_developer_EPEL repositories are enabled, or where software from these repositories is currently installed on the systems where Kubernetes runs. Even if you follow the instructions in this document, you may render your platform unsupported if these repositories or channels are enabled or software from these channels or repositories is installed on your system.
