Chapter 2. Enabling file system access for containers on Red Hat Enterprise Linux based nodes
Deploying OpenShift Container Storage on an OpenShift Container Platform with worker nodes on a Red Hat Enterprise Linux base in a user provisioned infrastructure (UPI) does not automatically provide container access to the underlying Ceph file system.
Skip this step for hosts based on Red Hat Enterprise Linux CoreOS (RHCOS).
- Log in to the Red Hat Enterprise Linux based node and open a terminal.
For each node in your cluster:
Verify that the node has access to the rhel-7-server-extras-rpms repository.
# subscription-manager repos --list-enabled | grep rhel-7-server
If you do not see both
rhel-7-server-extras-rpmsin the output, or if there is no output, run the following commands to enable each repository.
# subscription-manager repos --enable=rhel-7-server-rpms # subscription-manager repos --enable=rhel-7-server-extras-rpms
Install the required packages.
# yum install -y policycoreutils container-selinux
Persistently enable container use of the Ceph file system in SELinux.
