How to use an Edge Storage bucket as the origin of a static edge application

This guide walks you through setting a bucket as origin of an edge application using the Azion API, Azion CLI, and Azion Runtime.

Go to Edge Storage reference

There are separate instructions for API v3 using legacy Origin settings and API v4 using the new Edge Connector product.

Create a bucket and upload files

This section describes how you can upload objects to a bucket and maintain project structure using the Azion API. In this scenario, you’ll create a static application using two files, distributed into folders as follows:

src/index.html
src/styles/style.css
  1. Create the following index.html file inside of a local src directory:
src/index.html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
  <link rel="stylesheet" href="styles/style.css">
</head>
<body>
  <h1>Hello world!</h1>
  <p>I am an object from a bucket.</p>
</body>
</html>
  1. Now create the style.css file, which is referenced in the HTML, under the styles folder in the same directory:
src/styles/style.css
body {
background-color: black;
}


h1, p {
  color: #F3652B;
}
  1. Run the following POST request in your terminal, replacing [TOKEN VALUE] with your personal token and writing the desired bucket name in name to create a read-only bucket:
Terminal window
curl --location 'https://api.azion.com/v4/storage/buckets' --header 'Accept: application/json;' --header 'Content-Type: application/json' --header 'Authorization: Token [TOKEN VALUE]' --data '{
  "name": "app-origin",
  "edge_access": "read_only"
}'
  1. You should receive the following response:
{
"state": "executed",
"data": {
  "name": "app-origin",
  "edge_access": "read_only"
}
}

  1. Run the following POST requests in your terminal for each file, replacing <bucket_name> with the name of the bucket you just created:

    • For the index.html file, run the following command using src/index.html as the object key, and adding the object path as data:
Terminal window
curl --location 'https://api.azion.com/v4/storage/buckets/<bucket_name>/objects/src/index.html' --header 'Accept: application/json;' --header 'Content-Type: text/html' --header 'Authorization: Token [TOKEN VALUE]' --data '@./src/index.html'
  • For the styles.css file, run the following command using src/styles/style.css as the object key, and adding the object path as data:
Terminal window
curl --location 'https://api.azion.com/v4/storage/buckets/<bucket_name>/objects/src/styles/style.css' --header 'Accept: application/json;' --header 'Content-Type: text/css' --header 'Authorization: Token [TOKEN VALUE]' --data '@./src/styles/style.css'
  1. You should receive the following responses for the files:
{
  "state": "executed",
  "data": {
      "object_key": "src/index.html"
  }
}
{
  "state": "executed",
  "data": {
      "object_key": "src/styles/style.css"
  }
}

Create an edge application and set origin type to Edge Storage

Now that your bucket is populated with files, you can create a new edge application and a domain to set the bucket as the origin of the content and serve these objects.

To facilitate this process, use the Edge Application Proxy template:

  1. Access Azion Console.
  2. On the homepage, select the + Create option.
  3. Find the Edge Application Proxy card in the templates section and select it.
  4. Give your application an easy-to-remember name.
  5. In Route to bypass, type / to specify the root path of the application.
  6. Wait for the deployment process to finish.
  7. Copy the domain of the application, in the format http://xxxxxxxxxx.map.azionedge.net/.

Now you need to configure a new Edge Connector to link your application to your Edge Storage bucket. To do so:

  1. Access Azion Console > Edge Connector.
  2. Click the + Edge Connector button.
  3. In the General section, give your connector a unique and descriptive name (e.g., My Edge Storage Connector).
  4. In the Connector Type section, select Edge Storage.
  5. In the Connection Options section:
    • For Bucket, select the name of the bucket you created in the previous steps.
    • For Prefix, enter /src (or the prefix you used when uploading your objects).
  6. Set the Status to Active.
  7. Click the Save button.

To activate the Edge Connector in your edge application:

  1. Access the Rules Engine tab.
  2. Edit the default rule or add a new request rule.
  3. In the Criteria section, to apply the Edge Connector for your whole application, set the criteria to If ${uri} starts with /.
  4. In the Behavior section, select the Set Edge Connector behavior.
  5. Select the Edge Connector you want to apply.
  6. Click the Save button.
  7. Wait some time for the changes to propagate to the edge.

Once the changes have been made, access http://xxxxxxxxxx.map.azionedge.net/index.html to see the HTML file you uploaded with the applied CSS style.
