Kubernetes Cluster on Azure and Expose Couchbase Service

This blog is part of a multi-part blog series that shows how to run your applications on Kubernetes. It will use the Couchbase, an open source NoSQL distributed document database, as the  Docker container.

This fourth part will show:

  • How to setup and start the Kubernetes cluster on Azure
  • Run Docker container in the Kubernetes cluster
  • Expose Pod on Kubernetes as Service
  • Shutdown the cluster

Many thanks to @colemickens  for helping me through this recipe. This blog content is heavily based upon the instructions at colemickens.github.io/docs/getting-started-guides/azure/.

Install and Configure Azure CLI

Azure CLI is a command-line interface to develop, deploy and manage Azure applications. This is needed in order to install Kubernetes cluster on Azure.

  • Install Node:
brew install node
==> Downloading https://homebrew.bintray.com/bottles/node-6.2.0.yosemite.bottle.tar.gz
######################################################################## 100.0%
==> Pouring node-6.2.0.yosemite.bottle.tar.gz
==> Caveats
Please note by default only English locale support is provided. If you need
full locale support you should either rebuild with full icu:
  `brew reinstall node --with-full-icu`
or add full icu data at runtime following:
  https://github.com/nodejs/node/wiki/Intl#using-and-customizing-the-small-icu-build
 
Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

  • Install Azure CLI:
npm install -g azure-cli
/usr/local/bin/azure -> /usr/local/lib/node_modules/azure-cli/bin/azure
 
> fibers@1.0.13 install /usr/local/lib/node_modules/azure-cli/node_modules/fibers

Note the value shown instead of XXX and YYY. These will be used to configure the Kubernetes cluster.

Start Kubernetes Cluster

  • Download Kubernetes 1.2.4 and extract it.
  • Kubernetes cluster on Azure can be started as:
export KUBERNETES_PROVIDER=azure
export AZURE_SUBSCRIPTION_ID=XXX
export AZURE_TENANT_ID=YYY
./cluster/kube-up.sh

Make sure to specify the appropriate values for XXX and YYY from the previous command. AZURE_SUBSCRIPTION_ID andAZURE_TENANT_ID are specific to Azure.
These values can also be edited in cluster/azure/config-default.sh.

Kubernetes master is running at https://kube-20160531-161525.westus.cloudapp.azure.com:6443

It starts four nodes of Standard_A1 size. Each node gives you 1 core, 1.75 GB RAM, and 40GB HDD.

Run Docker Container in Kubernetes Cluster on Azure

Now that the cluster is up and running, get a list of all the nodes:

Four instances are created as shown – one for master node and three for worker nodes.

Azure Portal shows all the created artifacts in the Resource Group:

Create a Couchbase pod:

./kubernetes/cluster/kubectl.sh run couchbase --image=arungupta/couchbase
deployment "couchbase" created

Notice, how the image name can be specified on the CLI. Kubernetes pre-1.2 versions created a Replication Controller with this command. This is explained in  Kubernetes on Amazon Web Services or Kubernetes on Google Cloud. Kubernetes 1.2 introduced Deployments and so this creates a Deployment instead. This enables simplified application deployment and management including versioning, multiple simultaneous rollouts, aggregating status across all pods, maintaining application availability and rollback.

The pod uses arungupta/couchbase Docker image that provides a pre-configured Couchbase server. Any Docker image can be specified here.

Status of the pod can be watched:

./kubernetes/cluster/kubectl.sh get -w po
NAME                         READY     STATUS              RESTARTS   AGE

Expose Pod on Kubernetes as Service

Now that our pod is running, how do I access the Couchbase server? You need to expose the Deployment as a Service outside the Kubernetes cluster.

Typically, this will be exposed using the command:

./kubernetes/cluster/kubectl.sh expose deployment couchbase --target-port=8091 --port=8091 --type=LoadBalancer

But Azure does not support --type=LoadBalancer at this time. This feature is being worked upon and will hopefully be available in the near future. So in the meanwhile, we’ll expose the Service as:

./kubernetes/cluster/kubectl.sh expose deployment couchbase --target-port=8091 --port=8091
service "couchbase" exposed

Now proxy to this Service using kubectl proxy command:

./kubernetes/cluster/kubectl.sh proxy --address='0.0.0.0' --port=9999 --accept-hosts='.*'
Starting to serve on [::]:9999

And now this exposed Service is accessible at http://127.0.0.1:9999/api/v1/proxy/namespaces/default/services/couchbase/index.html. This shows the login screen of Couchbase Web Console:

azure-kubernetes-couchbase-web-console

Shutdown Kubernetes Cluster

Finally, shutdown the cluster using cluster/kube-down.sh script.

./kubernetes/cluster/kube-down.sh 
Bringing down cluster using provider: azure
Bringing down cluster
 
You must do this manually (for now)!
This can be done with:
./kubernetes/cluster/../cluster/../cluster/azure/util.sh: line 246: AZ_RESOURCE_GROUP: unbound variable

This script shuts down the cluster but the Azure resource group need to be explicitly removed. This can be done by selecting the Resource Group from portal.azure.com:

azure-portal-kubernetes-delete-resource-group

This is filed as #26601.

Enjoy!
