4.3. Deploying the Containers

List out the hostnames of the nodes on which the Red Hat Gluster Storage container has to be deployed:

oc get nodes

# oc get nodes

oc get nodes

# oc get nodes

NAME                    STATUS                     AGE
node1.example.com       Ready                      12d
node2.example.com       Ready                      12d

Deploy a Red Hat Gluster Storage container on a node by executing the following command:

oc process glusterfs -v GLUSTERFS_NODE=<node_hostname> | oc create -f -

# oc process glusterfs -v GLUSTERFS_NODE=<node_hostname> | oc create -f -

For example:

oc process glusterfs -v GLUSTERFS_NODE=node1.example.com | oc create -f -

# oc process glusterfs -v GLUSTERFS_NODE=node1.example.com | oc create -f -

deploymentconfig "glusterfs-dc-node1.example.com" created

Repeat the step of deploying the Red Hat Gluster Storage container on each node.

Note

This command deploys a single Red Hat Gluster Storage container on the node. 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 deploy heketi:

oc process deploy-heketi -v \
    HEKETI_KUBE_NAMESPACE=<Project name> \
    HEKETI_KUBE_APIHOST='<OpenShift master endpoint address>' \
    HEKETI_KUBE_INSECURE=y \
    HEKETI_KUBE_USER=<user name> \
    HEKETI_KUBE_PASSWORD=<password> | oc create -f -

# oc process deploy-heketi -v \
    HEKETI_KUBE_NAMESPACE=<Project name> \
    HEKETI_KUBE_APIHOST='<OpenShift master endpoint address>' \
    HEKETI_KUBE_INSECURE=y \
    HEKETI_KUBE_USER=<user name> \
    HEKETI_KUBE_PASSWORD=<password> | oc create -f -

oc process deploy-heketi -v \

    HEKETI_KUBE_APIHOST='https://master.example.com:8443' \
    HEKETI_KUBE_INSECURE=y \
    HEKETI_KUBE_USER=test-admin \
    HEKETI_KUBE_PASSWORD=admin | oc create -f -

# oc process deploy-heketi -v \
    HEKETI_KUBE_NAMESPACE=storage-project \
    HEKETI_KUBE_APIHOST='https://master.example.com:8443' \
    HEKETI_KUBE_INSECURE=y \
    HEKETI_KUBE_USER=test-admin \
    HEKETI_KUBE_PASSWORD=admin | oc create -f -

service "deploy-heketi" created
route "deploy-heketi" created
deploymentconfig "deploy-heketi" created
