# NGINX on AWS ECS Fargate using Python
A container running in AWS ECS Fargate, using Python infrastructure as code
- Source on GitHub: https://github.com/pulumi/examples/tree/master/aws-py-fargate
## Get started with this example
This example lives in the [pulumi/examples](https://github.com/pulumi/examples/tree/master/aws-py-fargate) repo. Pull down just this directory to follow along:
```bash
git clone --filter=blob:none --sparse https://github.com/pulumi/examples pulumi-examples
git -C pulumi-examples sparse-checkout set aws-py-fargate
cd pulumi-examples/aws-py-fargate
```
This example shows authoring Infrastructure as Code in Python. It
provisions a full [Amazon Elastic Container Service (ECS) "Fargate"](https://aws.amazon.com/ecs) cluster and
related infrastructure, running a load-balanced NGINX web server accessible over the Internet on port 80.
This example is inspired by [Docker's Getting Started Tutorial](https://docs.docker.com/get-started/).
## Prerequisites
* [Install Pulumi](https://www.pulumi.com/docs/get-started/install/)
* [Configure Pulumi to Use AWS](https://www.pulumi.com/docs/intro/cloud-providers/aws/setup/) (if your AWS CLI is configured, no further changes are required)
## Running the Example
Clone [the examples repo](https://github.com/pulumi/examples/tree/master/aws-py-fargate) and `cd` into it.
Next, to deploy the application and its infrastructure, follow these steps:
1. Create a new stack, which is an isolated deployment target for this example:
```bash
$ pulumi stack init dev
```
1. Set your desired AWS region:
```bash
$ pulumi config set aws:region us-east-1 # any valid AWS region will work
```
1. Deploy everything with a single `pulumi up` command. This will show you a preview of changes first, which
includes all of the required AWS resources (clusters, services, and the like). Don't worry if it's more than
you expected -- this is one of the benefits of Pulumi, it configures everything so that so you don't need to!
```bash
$ pulumi up
```
After being prompted and selecting "yes", your deployment will begin. It'll complete in a few minutes:
```bash
Updating (dev):
Type Name Status
+ pulumi:pulumi:Stack aws-py-fargate-dev created
+ ├─ aws:ecs:Cluster cluster created
+ ├─ aws:ec2:SecurityGroup web-secgrp created
+ ├─ aws:iam:Role task-exec-role created
+ ├─ aws:lb:TargetGroup app-tg created
+ ├─ aws:ecs:TaskDefinition app-task created
+ ├─ aws:iam:RolePolicyAttachment task-exec-policy created
+ ├─ aws:lb:LoadBalancer app-lb created
+ ├─ aws:lb:Listener web created
+ └─ aws:ecs:Service app-svc created
Outputs:
url: "app-lb-ad43707-1433933240.us-west-2.elb.amazonaws.com"
Resources:
+ 10 created
Duration: 2m56s
Permalink: https://app.pulumi.com/acmecorp/aws-python-fargate/dev/updates/1
```
Notice that the automatically assigned load-balancer URL is printed as a stack output.
1. At this point, your app is running -- let's curl it. The CLI makes it easy to grab the URL:
```bash
$ curl http://$(pulumi stack output url)
Welcome to nginx!
Welcome to nginx!
If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.
For online documentation and support please refer to
nginx.org.
Commercial support is available at
nginx.com.
Thank you for using nginx.
```
**Please Note**: It may take a few minutes for the app to start up. Until that point, you may receive a 503 error response code.
1. Try making some changes, and rerunning `pulumi up`. For example, let's scale up to 3 instances:
Running `pulumi up` will show you the delta and then, after confirming, will deploy just those changes:
```bash
$ pulumi up
```
Notice that `pulumi up` redeploys just the parts of the application/infrastructure that you've edited.
```bash
Updating (dev):
Type Name Status Info
pulumi:pulumi:Stack aws-py-fargate-dev
~ └─ aws:ecs:Service app-svc updated [diff: ~desiredCount]
Outputs:
url: "app-lb-ad43707-1433933240.us-west-2.elb.amazonaws.com"
Resources:
~ 1 updated
9 unchanged
Duration: 14s
Permalink: https://app.pulumi.com/acmecorp/aws-python-fargate/dev/updates/2
```
1. Once you are done, you can destroy all of the resources, and the stack:
```bash
$ pulumi destroy
$ pulumi stack rm
```
