4.1. Preparing the Red Hat OpenShift Container Platform Cluster
リンクのコピー

Execute the following steps to prepare the Red Hat OpenShift Container Platform cluster:
  1. On the master or client, execute the following command to login as the cluster admin user: 
    # oc login
    Copy to Clipboard Toggle word wrap
    For example: 
     oc login
Authentication required for https://dhcp46-24.lab.eng.blr.redhat.com:8443 (openshift)
Username: test
Password:
Login successful.

You have access to the following projects and can switch between them with 'oc project <project_name>':

    default
    kube-system
    logging
    management-infra
    openshift
    openshift-infra
  * storage-project

Using project "storage-project".

  2. On the master or client, execute the following command to create a project, which will contain all the containerized Red Hat Gluster Storage services: 
    # oc new-project <project_name>
    Copy to Clipboard Toggle word wrap
    For example: 
    # oc new-project storage-project

Now using project "storage-project" on server "https://master.example.com:8443"
    Copy to Clipboard Toggle word wrap
  3. After the project is created, execute the following command on the master node to enable the deployment of the privileged containers as Red Hat Gluster Storage container can only run in the privileged mode. 
    # oadm policy add-scc-to-user privileged -z storage-project
    Copy to Clipboard Toggle word wrap
  4. Execute the following steps on the master to set up the router:

    Note

    If a router already exists, proceed to Step 5.
    1. Execute the following command to enable the deployment of the router: 
      # oadm policy add-scc-to-user privileged -z router
# oadm policy add-scc-to-user privileged -z default
      Copy to Clipboard Toggle word wrap
    2. Execute the following command to deploy the router: 
      # oadm router storage-project-router --replicas=1
      Copy to Clipboard Toggle word wrap
    3. Edit the subdomain name in the config.yaml file located at /etc/origin/master/master-config.yaml.
      For example: 
      subdomain: "cloudapps.mystorage.com"
      Copy to Clipboard Toggle word wrap
    4. Restart the master OpenShift services by executing the following command: 
      # systemctl restart atomic-openshift-master
      Copy to Clipboard Toggle word wrap

      Note

      If the router setup fails, use the port forward method as described in Appendix C, Client Configuration using Port Forwarding .
    For more information regarding router setup, see https://access.redhat.com/documentation/en/openshift-container-platform/3.5/paged/installation-and-configuration/chapter-4-setting-up-a-router
  5. Execute the following command to verify if the router is running: 
    # oc get dc <router_name>
    Copy to Clipboard Toggle word wrap
    For example: 
    # oc get dc storage-project-router
NAME                   REVISION   DESIRED   CURRENT   TRIGGERED BY
storage-project-router   1          1         1         config
    Copy to Clipboard Toggle word wrap

    Note

    Ensure you do not edit the /etc/dnsmasq.conf file until the router has started.
  6. After the router is running, the client has to be setup to access the services in the OpenShift cluster. Execute the following steps on the client to set up the DNS.
    1. Edit the /etc/dnsmasq.conf file and add the following line to the file: 
      address=/.cloudapps.mystorage.com/<Router_IP_Address>
      Copy to Clipboard Toggle word wrap
      where, Router_IP_Address is the IP address of the node where the router is running.
    2. Restart the dnsmasq service by executing the following command: 
      # systemctl restart dnsmasq
      Copy to Clipboard Toggle word wrap
    3. Edit /etc/resolv.conf and add the following line: 
      nameserver 127.0.0.1
      Copy to Clipboard Toggle word wrap
    For more information regarding setting up the DNS, see https://access.redhat.com/documentation/en/openshift-container-platform/3.5/single/installation-and-configuration/#envirornment-requirements.
