# eks-minimal
2+
3+
This example demonstrates consuming
4+
[Pulumi AWS EKS Components](https://github.com/pulumi/pulumi-eks)
5+
from Java.
6+
7+
The high-level Cluster component automatically provisions roles,
8+
security groups and other necessary resources with good defaults,
9+
making it easy to get started. For more information, checkout the
10+
relevant
11+
[Pulumi blog](https://www.pulumi.com/blog/easily-create-and-manage-aws-eks-kubernetes-clusters-with-pulumi)
12+
13+
14+
## Running the example
15+
16+
1. Start a new stack:
17+
18+
```bash
19+
pulumi stack init dev
20+
```
21+
22+
1. Configure your AWS region, for example:
23+
24+
```bash
25+
pulumi config set aws:region us-east-1
26+
```
27+
28+
1. Deploy the example. Note it will take up to 10 minutes to provision
29+
the EKS cluster:
30+
31+
```bash
32+
pulumi up
33+
```
34+
35+
1. Access the Kubernetes Cluster using `kubectl`.
36+
37+
To access your new Kubernetes cluster using `kubectl`, we need to
38+
setup the `kubeconfig` file and download `kubectl`. We can leverage
39+
the Pulumi stack output in the CLI, as Pulumi facilitates exporting
40+
these objects for us.
41+
42+
```bash
43+
$ pulumi stack output kubeconfig --show-secrets > kubeconfig
44+
$ export KUBECONFIG=$PWD/kubeconfig
45+
$ kubectl version
46+
$ kubectl cluster-info
47+
$ kubectl get nodes
48+
```

# Web Server Using Amazon EC2
2+
3+
This example deploys a simple AWS EC2 virtual machine running a Python web server.
4+
5+
## Deploying the App
6+
7+
To deploy your infrastructure, follow the below steps.
8+
9+
### Prerequisites
10+
11+
1. [Install Pulumi](https://www.pulumi.com/docs/get-started/install/)
12+
2. [Configure AWS Credentials](https://www.pulumi.com/docs/intro/cloud-providers/aws/setup/)
13+
14+
### Steps
15+
16+
After cloning this repo, from this working directory, run these commands:
17+
18+
1. Create a new stack, which is an isolated deployment target for this example:
19+
20+
```bash
21+
$ pulumi stack init
22+
```
23+
24+
2. Set the required configuration variables for this program:
25+
26+
```bash
27+
$ pulumi config set aws:region us-east-1
28+
```
29+
30+
3. Stand up the VM, which will also boot up your Python web server on port 80:
31+
32+
```bash
33+
$ pulumi up
34+
```
35+
36+
4. After a couple minutes, your VM will be ready, and two stack outputs are printed:
37+
38+
```bash
39+
$ pulumi stack output
40+
Current stack outputs (2):
41+
OUTPUT VALUE
42+
publicHostName ec2-53-40-227-82.compute-1.amazonaws.com
43+
publicIp 53.40.227.82
44+
```
45+
46+
5. Thanks to the security group making port 80 accessible to the 0.0.0.0/0 CIDR block (all addresses), we can curl it:
47+
48+
```bash
49+
$ curl $(pulumi stack output publicIp)
50+
Hello, World!
51+
```
52+
53+
6. From there, feel free to experiment. Simply making edits and running `pulumi up` will incrementally update your VM.
54+
55+
7. Afterwards, destroy your stack and remove it:
56+
57+
```bash
58+
$ pulumi destroy --yes
59+
$ pulumi stack rm --yes
60+
```
