# Getting started on AWS EC2
|
|
|
|
## Prerequisites
|
|
|
|
1. You need an AWS account. Visit [http://aws.amazon.com](http://aws.amazon.com) to get started
|
|
2. Install and configure [AWS Command Line Interface](http://aws.amazon.com/cli)
|
|
3. You need an AWS [instance profile and role](http://docs.aws.amazon.com/IAM/latest/UserGuide/instance-profiles.html) with EC2 full access.
|
|
|
|
## Cluster turnup
|
|
### Supported procedure: `get-kube`
|
|
```bash
|
|
#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](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/cluster/kube-up.sh)
|
|
which in turn calls [cluster/aws/util.sh](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/cluster/aws/util.sh)
|
|
using [cluster/aws/config-default.sh](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/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](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/cluster/aws/config-default.sh) to change this behavior as follows:
|
|
|
|
```bash
|
|
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](aws-coreos.md) allows you to setup a Kubernetes cluster based on [CoreOS](http://www.coreos.com), either using
|
|
AWS CloudFormation or EC2 with user data (cloud-config).
|
|
|
|
## Getting started with your cluster
|
|
### Command line administration tool: `kubectl`
|
|
Copy the appropriate `kubectl` binary to any location defined in your `PATH` environment variable, for example:
|
|
|
|
```bash
|
|
# OS X
|
|
sudo cp kubernetes/platforms/darwin/amd64/kubectl /usr/local/bin/kubectl
|
|
|
|
# Linux
|
|
sudo cp kubernetes/platforms/linux/amd64/kubectl /usr/local/bin/kubectl
|
|
```
|
|
|
|
An up-to-date documentation page for this tool is available here: [kubectl manual](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/kubectl.md)
|
|
|
|
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](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/kubeconfig-file.md)
|
|
|
|
### Examples
|
|
See [a simple nginx example](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/examples/simple-nginx.md) to try out your new cluster.
|
|
|
|
The "Guestbook" application is another popular example to get started with Kubernetes: [guestbook example](https://github.com/GoogleCloudPlatform/kubernetes/tree/master/examples/guestbook)
|
|
|
|
For more complete applications, please look in the [examples directory](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/examples)
|
|
|
|
## 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:
|
|
|
|
```bash
|
|
cluster/kube-down.sh
|
|
```
|
|
|
|
## Further reading
|
|
Please see the [Kubernetes docs](https://github.com/GoogleCloudPlatform/kubernetes/tree/master/docs) for more details on administering
|
|
and using a Kubernetes cluster.
