4.2. Deploying Red Hat Openshift Container Storage in Converged Mode
- In your inventory file, include the following variables in the
[OSEv3:vars]section, adjusting them as needed for your configuration:[OSEv3:vars] openshift_storage_glusterfs_namespace=app-storage openshift_storage_glusterfs_storageclass=true openshift_storage_glusterfs_storageclass_default=false openshift_storage_glusterfs_block_deploy=true openshift_storage_glusterfs_block_host_vol_create=true openshift_storage_glusterfs_block_host_vol_size=100 openshift_storage_glusterfs_block_storageclass=true openshift_storage_glusterfs_block_storageclass_default=false
- In your inventory file, add
glusterfsin the[OSEv3:children]section to enable the[glusterfs]group:[OSEv3:children] masters etcd nodes glusterfs
- Add a
[glusterfs]section with entries for each storage node that will host the GlusterFS storage. For each node, setglusterfs_devicesto a list of raw block devices that will be completely managed as part of a GlusterFS cluster. There must be at least one device listed. Each device must be bare, with no partitions or LVM PVs. Specifying the variable takes the form:<hostname_or_ip> glusterfs_devices='[ "</path/to/device1/>", "</path/to/device2>", ... ]'
For example:[glusterfs] node11.example.com glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node12.example.com glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node13.example.com glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node14.example.com glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]'
- Add the hosts listed under
[glusterfs]to the[nodes]group:[nodes] ... node11.example.com openshift_node_group_name="node-config-infra" node12.example.com openshift_node_group_name="node-config-infra" node13.example.com openshift_node_group_name="node-config-infra" node14.example.com openshift_node_group_name="node-config-infra"
- The preceding steps detail options that need to be added to a larger, complete inventory file. To use the complete inventory file to deploy {gluster} provide the file path as an option to the following playbooks:
- For an initial OpenShift Container Platform installation:
ansible-playbook -i <path_to_inventory_file> /usr/share/ansible/openshift-ansible/playbooks/prerequisites.yml ansible-playbook -i <path_to_inventory_file> /usr/share/ansible/openshift-ansible/playbooks/deploy_cluster.yml
- For a standalone installation onto an existing OpenShift Container Platform cluster:
ansible-playbook -i <path_to_inventory_file> /usr/share/ansible/openshift-ansible/playbooks/openshift-glusterfs/config.yml
- To verify the deployment see, Section 4.6, “Verify your Deployment”.
