# Getting started on Amazon EC2 with CoreOS
The example below creates an elastic Kubernetes cluster with a custom number of worker nodes and a master.
**Warning:** contrary to the [supported procedure](aws.md), the examples below provision Kubernetes with an insecure API server (plain HTTP,
no security tokens, no basic auth). For demonstration purposes only.
## Highlights
* Cluster bootstrapping using [cloud-config](https://coreos.com/docs/cluster-management/setup/cloudinit-cloud-config/)
* Cross container networking with [flannel](https://github.com/coreos/flannel#flannel)
* Auto worker registration with [kube-register](https://github.com/kelseyhightower/kube-register#kube-register)
* Kubernetes v0.19.3 [official binaries](https://github.com/GoogleCloudPlatform/kubernetes/releases/tag/v0.19.3)
## Prerequisites
* [aws CLI](http://aws.amazon.com/cli)
* [CoreOS image for AWS](https://coreos.com/docs/running-coreos/cloud-providers/ec2/)
* [kubectl CLI](aws/kubectl.md) ([installation](aws.md#command-line-administration-tool-kubectl))
## Starting a Cluster
### CloudFormation
The [cloudformation-template.json](aws/cloudformation-template.json) can be used to bootstrap a Kubernetes cluster with a single command:
```bash
aws cloudformation create-stack --stack-name kubernetes --region us-west-2 \
--template-body file://aws/cloudformation-template.json \
--parameters ParameterKey=KeyPair,ParameterValue=<keypair> \
ParameterKey=ClusterSize,ParameterValue=<cluster_size> \
ParameterKey=VpcId,ParameterValue=<vpc_id> \
ParameterKey=SubnetId,ParameterValue=<subnet_id> \
ParameterKey=SubnetAZ,ParameterValue=<subnet_az>
```
It will take a few minutes for the entire stack to come up. You can monitor the stack progress with the following command:
```bash
aws cloudformation describe-stack-events --stack-name kubernetes
```
Record the Kubernetes Master IP address:
```bash
aws cloudformation describe-stacks --stack-name kubernetes
```
[Skip to kubectl client configuration](#configure-the-kubectl-ssh-tunnel)
### AWS CLI
The following commands shall use the latest CoreOS alpha AMI for the `us-west-2` region. For a list of different regions and corresponding AMI IDs see the [CoreOS EC2 cloud provider documentation](https://coreos.com/docs/running-coreos/cloud-providers/ec2/#choosing-a-channel).
#### Create the Kubernetes Security Group
```bash
aws ec2 create-security-group --group-name kubernetes --description "Kubernetes Security Group"
aws ec2 authorize-security-group-ingress --group-name kubernetes --protocol tcp --port 22 --cidr 0.0.0.0/0
aws ec2 authorize-security-group-ingress --group-name kubernetes --protocol tcp --port 80 --cidr 0.0.0.0/0
aws ec2 authorize-security-group-ingress --group-name kubernetes --source-security-group-name kubernetes
```
#### Save the master and node cloud-configs
* [master.yaml](aws/cloud-configs/master.yaml)
* [node.yaml](aws/cloud-configs/node.yaml)
#### Launch the master
*Attention:* replace `<ami_image_id>` below for a [suitable version of CoreOS image for AWS](https://coreos.com/docs/running-coreos/cloud-providers/ec2/).
```bash
aws ec2 run-instances --image-id <ami_image_id> --key-name <keypair> \
--region us-west-2 --security-groups kubernetes --instance-type m3.medium \
--user-data file://master.yaml
```
Record the `InstanceId` for the master.
Gather the public and private IPs for the master node:
```bash
aws ec2 describe-instances --instance-id <instance-id>
```
```json
{
"Reservations": [
{
"Instances": [
{
"PublicDnsName": "ec2-54-68-97-117.us-west-2.compute.amazonaws.com",
"RootDeviceType": "ebs",
"State": {
"Code": 16,
"Name": "running"
},
"PublicIpAddress": "54.68.97.117",
"PrivateIpAddress": "172.31.9.9",
```
#### Update the node.yaml cloud-config
Edit `node.yaml` and replace all instances of `<master-private-ip>` with the **private** IP address of the master node.
### Launch 3 worker nodes
*Attention:* Replace `<ami_image_id>` below for a [suitable version of CoreOS image for AWS](https://coreos.com/docs/running-coreos/cloud-providers/ec2/#choosing-a-channel).
```bash
aws ec2 run-instances --count 3 --image-id <ami_image_id> --key-name <keypair> \
--region us-west-2 --security-groups kubernetes --instance-type m3.medium \
--user-data file://node.yaml
```
### Add additional worker nodes
*Attention:* replace `<ami_image_id>` below for a [suitable version of CoreOS image for AWS](https://coreos.com/docs/running-coreos/cloud-providers/ec2/#choosing-a-channel).
```bash
aws ec2 run-instances --count 1 --image-id <ami_image_id> --key-name <keypair> \
--region us-west-2 --security-groups kubernetes --instance-type m3.medium \
--user-data file://node.yaml
```
### Configure the kubectl SSH tunnel
This command enables secure communication between the kubectl client and the Kubernetes API.
```bash
ssh -f -nNT -L 8080:127.0.0.1:8080 core@<master-public-ip>
```
### Listing worker nodes
Once the worker instances have fully booted, they will be automatically registered with the Kubernetes API server by the kube-register service running on the master node. It may take a few mins.
```bash
kubectl get nodes
```
## Starting a simple pod
Create a pod manifest: `pod.json`
```json
{
"apiVersion": "v1",
"kind": "Pod",
"metadata": {
"name": "hello",
"labels": {
"name": "hello",
"environment": "testing"
}
},
"spec": {
"containers": [{
"name": "hello",
"image": "quay.io/kelseyhightower/hello",
"ports": [{
"containerPort": 80,
"hostPort": 80
}]
}]
}
}
```
### Create the pod using the kubectl command line tool
```bash
kubectl create -f ./pod.json
```
### Testing
```bash
kubectl get pods
```
Record the **Host** of the pod, which should be the private IP address.
Gather the public IP address for the worker node.
```bash
aws ec2 describe-instances --filters 'Name=private-ip-address,Values=<host>'
```
```json
{
"Reservations": [
{
"Instances": [
{
"PublicDnsName": "ec2-54-68-97-117.us-west-2.compute.amazonaws.com",
"RootDeviceType": "ebs",
"State": {
"Code": 16,
"Name": "running"
},
"PublicIpAddress": "54.68.97.117",
```
Visit the public IP address in your browser to view the running pod.
### Delete the pod
```bash
kubectl delete pods hello
```
