A.2. Deploying the Containers
Execute the following commands to deploy the Red Hat Gluster Storage container on the nodes:
- List out the hostnames of the nodes on which the Red Hat Gluster Storage container has to be deployed:
# oc get nodes
For example:# oc get nodes NAME STATUS AGE node1.example.com Ready 12d node2.example.com Ready 12d node3.example.com Ready 12d master.example.com Ready,SchedulingDisabled 12d
- Execute the following command to label all nodes that will run Red Hat Gluster Storage pods:
# oc label node <NODENAME> storagenode=glusterfs
For example:# oc label nodes 192.168.90.3 storagenode=glusterfs node "192.168.90.3" labeled
Repeat this command for every node that will be in the GlusterFS cluster.Verify the label has set properly by running the following command:# oc get nodes --show-labels 192.168.90.2 Ready 12d beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,kubernetes.io/hostname=192.168.90.2,storagenode=glusterfs 192.168.90.3 Ready 12d beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,kubernetes.io/hostname=192.168.90.3,storagenode=glusterfs 192.168.90.4 Ready 12d beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,kubernetes.io/hostname=192.168.90.4,storagenode=glusterfs 192.168.90.5 Ready,SchedulingDisabled 12d beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,kubernetes.io/hostname=192.168.90.5
- Execute the following command to deploy the Red Hat Gluster Storage pods:
# oc process glusterfs | oc create -f - daemonset "glusterfs" created
Note
This does not initialize the hardware or create trusted storage pools. That aspect will be taken care by heketi which is explained in the further steps. - Execute the following command to grant the heketi Service Account the neccessary privileges:
# oc policy add-role-to-user edit system:serviceaccount:<project_name>:heketi-service-account # oc adm policy add-scc-to-user privileged -z heketi-service-account
For example:# oc policy add-role-to-user edit system:serviceaccount:storage-project:heketi-service-account # oc adm policy add-scc-to-user privileged -z heketi-service-account
- Execute the following command to deploy deploy-heketi:
# oc process deploy-heketi | oc create -f -
For example:# oc process deploy-heketi | oc create -f - service "deploy-heketi" created route "deploy-heketi" created deploymentconfig "deploy-heketi" created
- Execute the following command to verify that the containers are running:
# oc get pods
For example:# oc get pods NAME READY STATUS RESTARTS AGE storage-project-router-1-pj9ea 1/1 Running 0 1d deploy-heketi-1-m7x8g 1/1 Running 0 1m glusterfs-41lfl 1/1 Running 0 1m glusterfs-dtyr4 1/1 Running 0 1m glusterfs-ral2d 1/1 Running 0 1m
