Procedure

1. If you are not already, navigate to the IAM dashboard by clicking Dashboard.
2. In the navigation pane, click Roles under Access management.

3. Click Create role.

   • Click Custom Trust Policy, which shows an editable JSON policy. By default, it shows the following information:

     {
     	"Version": "2012-10-17",
     	"Statement": [
     		{
     			"Sid": "Statement1",
     			"Effect": "Allow",
     			"Principal": {},
     			"Action": "sts:AssumeRole"
     		}
     	]
     }

4. Under the Principal configuration field, add your AWS ARN information. For example:

   {
       "Version": "2012-10-17",
       "Statement": [
      	 {
      		 "Sid": "Statement1",
      		 "Effect": "Allow",
      		 "Principal": {
      		 	"AWS": "arn:aws:iam::123492922789:user/quay-user"
      		 },
      		 "Action": "sts:AssumeRole"
      	 }
       ]
   }

5. Click Next.
6. On the Add permissions page, type AmazonS3FullAccess in the search box. Check the box to add that policy to the S3 role, then click Next.

7. On the Name, review, and create page, enter the following information:

   1. Enter a role name, for example, example-role.
   2. Optional. Add a description.
8. Click the Create role button. You are navigated to the Roles page. Under Role name, the newly created S3 should be available.

Procedure

1. Update your config.yaml file for Red Hat Quay to include the following information:

   # ...
   DISTRIBUTED_STORAGE_CONFIG:
      default:
       - STSS3Storage
       - sts_role_arn: <role_arn> 1
         s3_bucket: <s3_bucket_name> 2
         storage_path: <storage_path> 3
         s3_region: <region> 4
         sts_user_access_key: <s3_user_access_key> 5
         sts_user_secret_key: <s3_user_secret_key> 6
   # ...

   1

   The unique Amazon Resource Name (ARN) required when configuring AWS STS

   2

   The name of your s3 bucket.

   3

   The storage path for data. Usually /datastorage.

   4

   Optional. The Amazon Web Services region. Defaults to us-east-1.

   5

   The generated AWS S3 user access key required when configuring AWS STS.

   6

   The generated AWS S3 user secret key required when configuring AWS STS.

2. Restart your Red Hat Quay deployment.

Verification

1. Tag a sample image, for example, busybox, that will be pushed to the repository. For example:

   $ podman tag docker.io/library/busybox <quay-server.example.com>/<organization_name>/busybox:test

2. Push the sample image by running the following command:

   $ podman push <quay-server.example.com>/<organization_name>/busybox:test

3. Verify that the push was successful by navigating to the Organization that you pushed the image to in your Red Hat Quay registry Tags.
4. Navigate to the Amazon Web Services (AWS) console and locate your s3 bucket.
5. Click the name of your s3 bucket.
6. On the Objects page, click datastorage/.

7. On the datastorage/ page, the following resources should seen:

   • sha256/

   • uploads/

     These resources indicate that the push was successful, and that AWS STS is properly configured.
