Add tags to ECR repository

This guide demonstrates how to add meaningful tags to your AWS ECR repository using Port's self-service action

Prerequisites

Port's GitHub app needs to be installed
AWS Access Key and Secret Key pair. Follow AWS guide on creating access keys to create one for your account
AWS AmazonEC2ContainerRegistryFullAccess policy should be enabled on the account to enable necessary permissions to carry out the action
Account ID. Click on the account dropdown settings on the upper right corner in your AWS Console to retrieve it
In your GitHub repository, go to Settings > Secrets and add the following secrets:
- AWS_REGION - The region where ECR repositories are located. Available regions can be found on the Regions, Availability Zones, and Local Zones page in AWS documentation.
- AWS_ACCOUNT_ID - AWS account ID from the prerequisites step
- AWS_ACCESS_KEY_ID - AWS Access Key ID
- AWS_SECRET_ACCESS_KEY - AWS Secret Access Key
- PORT_CLIENT_ID - Port Client ID learn more
- PORT_CLIENT_SECRET - Port Client Secret learn more
Optional - Ingest your AWS ECR Repository into Port using our recommended python script

ECR Repository Python Script

This step is not required for this example, but it will create all the blueprint boilerplate for you, and also update the catalog with your repositories.

AWS_REGION - The region where ECR repositories are located. Available regions can be found on the Regions, Availability Zones, and Local Zones page in AWS documentation.
AWS_ACCOUNT_ID - AWS account ID from the prerequisites step
AWS_ACCESS_KEY_ID - AWS Access Key
AWS_SECRET_ACCESS_KEY - AWS Secret Key, also gotten from the access key creation
PORT_CLIENT_ID - Port Client ID learn more
PORT_CLIENT_SECRET - Port Client Secret learn more

Create an AWS ECR repository blueprint in Port using the blueprint below:

ECR Repository Blueprint

{
  "identifier": "ecrRepository",
  "description": "This blueprint represents an ECR Repository",
  "title": "ECR Repository",
  "icon": "AWS",

        }
      },

        "type": "boolean",
        "title": "Configuration Scan on Push",
        "description": "Image scanning configuration when pushing images to this repository"
      },

        "description": "The encryption type of the repository",

        "enumColors": {

          "KMS": "blue"
        }
      },
      "kmsKey": {
        "type": "string",
        "title": "KMS Key",
        "description": "The KMS key used for encryption"
      }
    },
    "required": []
  },

  "aggregationProperties": {},
  "relations": {}
}

GitHub Workflow

While this step will ensure the ecrRepository blueprint is available, the self-service action supports selecting from the list of ingested repositories instead of having to input the repository name. To allow for this option, follow Port's guide to ingest images and repositories into Port.

This option is way easier but if you do not want this, you can simply type in repository names to tag them.

Create the Port action on the ecrRepository blueprint:
- Head to the self-service page.
- Click on the + New Action button.
- Click on the {...} Edit JSON button.
- Copy and paste the following JSON configuration into the editor:

Port Action: Add Tags to ECR Repository

Modification Required

<GITHUB-ORG> - your GitHub organization or user name.
<GITHUB-REPO-NAME> - your GitHub repository name.

Done! wait for the ECR repository to be tagged.

Congrats 🎉 You've tagged your ECR repository for the first time from Port!
