Get started with Pulumi and AWS

Create a component

Components are infrastructure abstractions that encapsulate complexity and enable sharing and reuse. Instead of copy-pasting common patterns, you can encode them as components.

You will now create your first component that packages up your S3 website so you can easily stamp out entire websites in just a few lines of code:

const website = new AwsS3Website("my-website", {
    files: [ "index.html" ],
});

const website = new AwsS3Website("my-website", {
    files: [ "index.html" ],
});

website = AwsS3Website('my-website', files=['index.html'])

website, err := NewAwsS3Website(ctx, "my-website", AwsS3WebsiteArgs{
    Files: []string{"index.html"},
})
if err != nil {
    return err
}

var website = new AwsS3Website("my-website", new AwsS3WebsiteArgs()
{
    Files = new[] { "index.html" }
});

var website = new AwsS3Website("my-website",
    new AwsS3WebsiteArgs(new String[] { "index.html" }));

Unfortunately, YAML lacks the language facilities to author components. Feel free to skip ahead.

Using components here also has the benefit that, as the requirements for S3 websites changes, you can update the one component definition and have all uses of it benefit.

Define a new component

To define a new component, create a class called AwsS3Website that derives from ComponentResource. It’ll have a mostly-empty constructor to start with but you will add the AWS S3 resources to it in the next step. You’ll also define the inputs for the component – the files to add to the website – and outputs – a single property with the website url.

This defines a component but it doesn’t do much yet.

Refactor your code into the component

Next, make four changes:

Unfortunately, YAML lacks the language facilities to author components. Feel free to skip ahead.

Instantiate the component

Now go back to your original file

TypeScript
JavaScript
Python
Go
C#
F#
VB
Java
YAML

index.js

index.ts

__main__.py

main.go

Program.cs

Program.fs

Program.vb

App.java

Pulumi.yaml

. Now that you have moved all of the resources, you can start over with a clean slate. Ensure the file is empty and we will build it back up by simply importing and instantiating our new component.

Add this to your now-empty

TypeScript
JavaScript
Python

YAML

index.js

exports.url = website.url;

// Import from our new component module:

Deploy the component

Now deploy the resulting component instantiation. To do so, run pulumi up as usual:

$ pulumi up

  details

This preview shows you a few things. First, you’ll see our AwsS3Website component with all of its children resources neatly parented underneath it. This helps to see what resources relate to which components. Next, you’ll see that your old resources are being destroyed.

If you’re wondering why Pulumi didn’t simply update the resources in place, it’s because certain changes – like refactoring resources into a component – fundamentally change a resource’s identity. Many changes like updating properties or moving resources between files are not disruptive like this. It such cases, you can assign aliases to prevent deletions from happening.

Accept the changes by selecting yes and the deployment will occur:

Now test out your new website – it works like before, just with a tidier codebase now!

$ curl $(pulumi stack output url)
<html>
    <body>
        <h1>Hello, Pulumi!</h1>
    </body>
</html>

> curl (pulumi stack output url)
<html>
    <body>
        <h1>Hello, Pulumi!</h1>
    </body>
</html>

Once you are ready to move on, let’s destroy everything we’ve spun up in this tutorial.
