The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
This chapter describes the prerequisites for the systems to be used in an installation of Oracle Linux Cloud Native Environment. This chapter also discusses how to enable the repositories to install the Oracle Linux Cloud Native Environment packages.
The Oracle Linux Cloud Native Environment packages are available on the Oracle Linux yum server in the
ol7_olcne11
repository, or on the
Unbreakable Linux Network (ULN) in the
ol7_x86_64_olcne11
channel, however there are
also dependencies across other repositories and channels, and
these must also be enabled on each system where Oracle Linux Cloud Native Environment is
installed.
Oracle does not support Kubernetes on systems where the
ol7_preview
, ol7_developer
or ol7_developer_EPEL
yum repositories or ULN
channels are enabled, or where software from these repositories
or channels 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.
If you are registered to use ULN, use the ULN web interface to subscribe the system to the appropriate channels.
To subscribe to the ULN channels:
Log in to https://linux.oracle.com with your ULN user name and password.
On the Systems tab, click the link named for the system in the list of registered machines.
On the System Details page, click Manage Subscriptions.
On the System Summary page, select each required channel from the list of available channels and click the right arrow to move the channel to the list of subscribed channels. Subscribe the system to the following channels:
ol7_x86_64_olcne11
ol7_x86_64_kvm_utils
ol7_x86_64_addons
ol7_x86_64_latest
ol7_x86_64_UEKR5
Click Save Subscriptions.
If you are using the Oracle Linux yum server for system updates, enable the required yum repositories.
To enable the yum repositories:
Install the
oracle-olcne-release-el7
release package to install the Oracle Linux Cloud Native Environment yum repository configuration.$
sudo yum install oracle-olcne-release-el7
Enable the following yum repositories:
ol7_olcne11
ol7_kvm_utils
ol7_addons
ol7_latest
ol7_UEKR5
Use the yum-config-manager tool to enable the yum repositories:
$
sudo yum-config-manager --enable ol7_olcne11 ol7_kvm_utils ol7_addons ol7_latest ol7_UEKR5
Make sure the
ol7_olcne
yum repository is disabled:$
sudo yum-config-manager --disable ol7_olcne
