WARNING WARNING WARNING WARNING WARNING

PLEASE NOTE: This document applies to the HEAD of the source tree

If you are using a released version of Kubernetes, you should refer to the docs that go with that version.

The latest 1.0.x release of this document can be found [here](http://releases.k8s.io/release-1.0/docs/getting-started-guides/aws.md).

Documentation for other releases can be found at releases.k8s.io.

Getting started on AWS EC2

Table of Contents

Prerequisites

  1. You need an AWS account. Visit http://aws.amazon.com to get started
  2. Install and configure AWS Command Line Interface
  3. You need an AWS instance profile and role with EC2 full access.

Cluster turnup

Supported procedure: get-kube

#Using wget
export KUBERNETES_PROVIDER=aws; wget -q -O - https://get.k8s.io | bash

#Using cURL
export KUBERNETES_PROVIDER=aws; curl -sS https://get.k8s.io | bash

NOTE: This script calls cluster/kube-up.sh which in turn calls cluster/aws/util.sh using cluster/aws/config-default.sh.

This process takes about 5 to 10 minutes. Once the cluster is up, the IP addresses of your master and node(s) will be printed, as well as information about the default services running in the cluster (monitoring, logging, dns). User credentials and security tokens are written in ~/.kube/kubeconfig, they will be necessary to use the CLI or the HTTP Basic Auth.

By default, the script will provision a new VPC and a 4 node k8s cluster in us-west-2a (Oregon) with t2.micro instances running on Ubuntu. You can override the variables defined in config-default.sh to change this behavior as follows:

export KUBE_AWS_ZONE=eu-west-1c
export NUM_MINIONS=2
export MINION_SIZE=m3.medium
export AWS_S3_REGION=eu-west-1
export AWS_S3_BUCKET=mycompany-kubernetes-artifacts
export INSTANCE_PREFIX=k8s
...

It will also try to create or reuse a keypair called "kubernetes", and IAM profiles called "kubernetes-master" and "kubernetes-minion". If these already exist, make sure you want them to be used here.

NOTE: If using an existing keypair named "kubernetes" then you must set the AWS_SSH_KEY key to point to your private key.

Alternatives

A contributed example allows you to setup a Kubernetes cluster based on CoreOS, either using AWS CloudFormation or EC2 with user data (cloud-config).

Getting started with your cluster

Command line administration tool: kubectl

The cluster startup script will leave you with a kubernetes directory on your workstation. Alternately, you can download the latest Kubernetes release from this page.

Next, add the appropriate binary folder to your PATH to access kubectl:

# OS X
export PATH=<path/to/kubernetes-directory>/platforms/darwin/amd64:$PATH

# Linux
export PATH=<path/to/kubernetes-directory>/platforms/linux/amd64:$PATH

An up-to-date documentation page for this tool is available here: kubectl manual

By default, kubectl will use the kubeconfig file generated during the cluster startup for authenticating against the API. For more information, please read kubeconfig files

Examples

See a simple nginx example to try out your new cluster.

The "Guestbook" application is another popular example to get started with Kubernetes: guestbook example

For more complete applications, please look in the examples directory

Tearing down the cluster

Make sure the environment variables you used to provision your cluster are still exported, then call the following script inside the kubernetes directory:

cluster/kube-down.sh
