OpenShift is Red Hat’s open source PaaS platform. OpenShift 3 provides a holistic experience of running your applications using Docker and Kubernetes. In a classic Red Hat way, all the work is done in the open source at OpenShift Origin. This also drives the next major release of OpenShift Online and OpenShift Enterprise.

OpenShift 3 using Docker and Kubernetes for container orchestration makes it really simple to bring any products that have a Docker image to run with minimal effort. This blog explains how to get started with Couchbase on OpenShift 3.

Getting Started with OpenShift 3

• Download the latest Vagrant box (1.1 as of this writing) and Vagrantfile from: openshift.org/vm/. Copy them in the same directory.Vagrantfile is configured for 2GB memory and can be updated if you need to run more containers. OpenShift Master, Node, Docker Registry, and other components run inside the VM.This blog was written using Vagrant 1.7.4 and VirtualBox 5.0.10r104061.
• Add the Vagrant Box:
  
  vagrant box add --name openshift3 openshift-bootstrap-1.1.box ==> box: Box file was not detected as metadata. Adding it directly... ==> box: Adding box 'openshift3' (v0) for provider: box: Unpacking necessary files from: file:///Users/arungupta/tools/openshiftv3/1.1/openshift-bootstrap-1.1.box ==> box: Successfully added box 'openshift3' (v0) for 'virtualbox'!

  vagrant box add --name openshift3 openshift-bootstrap-1.1.box ==> box: Box file was not detected as metadata. Adding it directly... ==> box: Adding box 'openshift3' (v0) for provider:     box: Unpacking necessary files from: file:///Users/arungupta/tools/openshiftv3/1.1/openshift-bootstrap-1.1.box ==> box: Successfully added box 'openshift3' (v0) for 'virtualbox'!

• Start the Virtual Machine:
  
  vagrant up Bringing machine 'default' up with 'virtualbox' provider... ==> default: Setting the name of the VM: openshift3 ==> default: Clearing any previously set network interfaces... ==> default: Preparing network interfaces based on configuration... default: Adapter 1: nat ==> default: Forwarding ports... default: 80 => 1080 (adapter 1) default: 443 => 1443 (adapter 1) default: 5000 => 5000 (adapter 1) default: 8080 => 8080 (adapter 1) default: 8443 => 8443 (adapter 1) default: 22 => 2222 (adapter 1) ==> default: Running 'pre-boot' VM customizations... ==> default: Booting VM... ==> default: Waiting for machine to boot.

Download and Configure OpenShift 3 Client

• Download Mac 64-bit client tools (gem install rhc is for v2 only) from openshift.org/vm/ and extract them a in directory. The listing looks like:
  
  tar xzvf ~/Downloads/openshift-origin-v1.1-ac7a99a-darwin-amd64.tar.gz x ./ x ./oadm x ./kube-scheduler x ./kubelet x ./kube-apiserver x ./openshift x ./kube-controller-manager x ./kube-proxy x ./oc x ./kubectl

  tar xzvf ~/Downloads/openshift-origin-v1.1-ac7a99a-darwin-amd64.tar.gz x ./ x ./oadm x ./kube-scheduler x ./kubelet x ./kube-apiserver x ./openshift x ./kube-controller-manager x ./kube-proxy x ./oc x ./kubectl

• Verify the client version:
  
  ./oc version oc v1.1 kubernetes v1.1.0-origin-1107-g4c8e6f4

  1 2 3 4 5

  ./oc version oc v1.1 kubernetes v1.1.0-origin-1107-g4c8e6f4

• Remove ~/.kube/configor rename to something else.
• Login to OpenShift:
  
  ./oc login Server [https://localhost:8443]: The server uses a certificate signed by an unknown authority. You can bypass the certificate check, but any data you send to the server could be intercepted by others. Use insecure connections? (y/n): y Authentication required for https://localhost:8443 (openshift) Username: admin Password: Login successful. You have access to the following projects and can switch between them with 'oc project <projectname>': * default (current) * openshift * turbo Using project "default". Welcome! See 'oc help' to get started.

Create Couchbase Application in OpenShift 3

• Create a new Couchbase instance:
  
  ./oc new-app arungupta/couchbase --> Found Docker image 9131c5a (2 days old) from Docker Hub for "arungupta/couchbase" * An image stream will be created as "couchbase:latest" that will track this image * This image will be deployed in deployment config "couchbase" * Ports 11207/tcp, 11210/tcp, 11211/tcp, 18091/tcp, 18092/tcp, 8091/tcp, 8092/tcp, 8093/tcp will be load balanced by service "couchbase" --> Creating resources with label app=couchbase ... ImageStream "couchbase" created DeploymentConfig "couchbase" created Service "couchbase" created --> Success Run 'oc status' to view your app.

  ./oc new-app arungupta/couchbase --> Found Docker image 9131c5a (2 days old) from Docker Hub for "arungupta/couchbase"     * An image stream will be created as "couchbase:latest" that will track this image     * This image will be deployed in deployment config "couchbase"     * Ports 11207/tcp, 11210/tcp, 11211/tcp, 18091/tcp, 18092/tcp, 8091/tcp, 8092/tcp, 8093/tcp will be load balanced by service "couchbase" --> Creating resources with label app=couchbase ...     ImageStream "couchbase" created     DeploymentConfig "couchbase" created     Service "couchbase" created --> Success     Run 'oc status' to view your app.

  arungupta/couchbase is used as it uses Couchbase REST API to preconfigure the Couchbase server with:
  • Memory and index quota
  • Query, Data, and Index service
  • Username and password credentials
  • Install travel-sample bucket

  This sample bucket will be used later for querying data.

• Check the status of deployment:

This blog shows the very basics of getting started with Couchbase on OpenShift 3. Future blogs will show:

• How to deploy an application to OpenShift and use this Couchbase
• How to make this application accessible outside OpenShift
• How to scale Couchbase in OpenShift
• Possibly some other interesting items that come along

Do you have a suggestion on what you’d like to see?
