Getting started on Microsoft Azure

Prerequisites

  1. You need an Azure account. Visit http://azure.microsoft.com/ to get started.

  2. Install and configure the Azure cross-platform command-line interface. http://azure.microsoft.com/en-us/documentation/articles/xplat-cli/

  3. Make sure you have a default account set in the Azure cli, using azure account set

  4. You must have Go (version 1.2 or later) installed: www.golang.org.

  5. Get the Kubernetes source:

     git clone https://github.com/GoogleCloudPlatform/kubernetes.git

Setup

The cluster setup scripts can setup Kubernetes for multiple targets. First modify cluster/kube-env.sh to specify azure:

KUBERNETES_PROVIDER="azure"

Next build Kubernetes, package the release, and upload to Azure Storage:

cd kubernetes
release/azure/release.sh

Next, specify an existing US West virtual network in /cluster/azure/config.sh:

AZ_VNET=<vnet name>
AZ_SUBNET=<subnet name>

Now you're ready.

You can then use the cluster/kube-*.sh scripts to manage your azure cluster, start with:

cluster/kube-up.sh

Running a container (simple version)

Once you have your instances up and running, the hack/build-go.sh script sets up your Go workspace and builds the Go components.

The cluster/kubecfg.sh script spins up two containers, running Nginx and with port 80 mapped to 8080:

cd kubernetes
hack/build-go.sh
cluster/kubecfg.sh -p 8080:80 run dockerfile/nginx 2 myNginx

To stop the containers:

cluster/kubecfg.sh stop myNginx

To delete the containers:

cluster/kubecfg.sh rm myNginx

Running a container (more complete version)

You can create a pod like this:

cd kubernetes
cluster/kubecfg.sh -c api/examples/pod.json create /pods

Where pod.json contains something like:

{
  "id": "php",
  "kind": "Pod",
  "apiVersion": "v1beta1",
  "desiredState": {
    "manifest": {
      "version": "v1beta1",
      "id": "php",
      "containers": [{
        "name": "nginx",
        "image": "dockerfile/nginx",
        "ports": [{
          "containerPort": 80,
          "hostPort": 8080
        }],
        "livenessProbe": {
          "enabled": true,
          "type": "http",
          "initialDelaySeconds": 30,
          "httpGet": {
            "path": "/index.html",
            "port": "8080"
          }
        }
      }]
    }
  },
  "labels": {
    "name": "foo"
  }
}

You can see your cluster's pods:

cluster/kubecfg.sh list pods

and delete the pod you just created:

cluster/kubecfg.sh delete pods/php

Look in api/examples/ for more examples

Tearing down the cluster

cd kubernetes
cluster/kube-down.sh
