How do you set a lifecycle policy for an ECR for tagged with any prefix?

Question

I want to set a lifecycle policy for my ECR. For all tagged images to have image count more than 1. It's currently set to Prefix and can't set it blank.

aws ecr policy console:

Thanks in advance.

Answer 1

Lifecycle policies on all tagged images is now supported in ECR

You can use it by selecting Any for "Image Status". Alternatively in JSON, you can create a rule with "tagStatus": "any":

{
    "rules": [
        {
            "rulePriority": 1,
            "description": "Rule 1",
            "selection": {
                "tagStatus": "any",
                "countType": "imageCountMoreThan",
                "countNumber": 1
            },
            "action": {
                "type": "expire"
            }
        }
    ]
}

Answer 2

Unfortunately it doesn't seem to be possible at the moment. The only solution I see is to create an own policy for each of characters [a-zA-Z0-9] so that each of these policies match to tagged images prefixed with that letter. Like this:

Policy 1: when tagged and prefixed with "a", expire after 30 days
Policy 2: when tagged and prefixed with "b", expire after 30 days
Policy 3: when tagged and prefixed with "c", expire after 30 days
...

Quite insane approach, but it'd work.

To be able to use policy wisely, one should start using some known tag prefixes. For example, one could tag all test images with prefix test- and release images with release-. Then it'd be sufficient to create policies for just these two prefixes.
