OpenShift 3.11 Local Storage Class

ConfigMap and Storage Class YAML to create a local SSD Storage Class

Getting Started

These instructions will configure and enable a local storage class in OpenShift 3.11. This allows for an SSD EBS volume to be attached to the node and mounted directly by pods on that node

Prerequisites

• OpenShift Cluster
• OC command line tool

Ensure EBS Volume is mounted in the correct location

Make sure the EBS volume is mounted to the host in the right path

/mnt/local-storage/ssd/disk#

SELinux

Change the SELinux labels so OCP can see the new EBS volume

chcon -R unconfined_u:object_r:svirt_sandbox_file_t:s0 /mnt/local-storage/

Create local storage project and configure

oc new-project local-storage
oc create serviceaccount local-storage-admin
oc adm policy add-scc-to-user privileged -z local-storage-admin
oc create -f https://raw.githubusercontent.com/openshift/origin/release-3.11/examples/storage-examples/local-examples/local-storage-provisioner-template.yaml
