    },
    "Action": [
        "ecr:BatchGetImage",
        "ecr:GetDownloadUrlForLayer"
    ]
} 

3. Change the Repo Name in

Package @todo

• Check if container repository exists (Creates if not exists) - Should be in pipeline helpers
• npm run build
• npm run package
• create a release tag on Github Repo
• publish image based on version specified by semantic release.

Deploy @todo

• Deploy a version to service's lambda by updating the image to release build version.
• And verify health check.
