AWS ECR Module

This module simplifies the creation of an ECR life cycle rule. And can be used in combination with doingcloudright/ecr-cross-account/aws. NB: Badly created ECR Lifecycle rules can cause great harm, it's important to review the created lifecycle rules.

Rules can be made for all available tag statuses [ tagged, untagged, any ], in combination with all count types [ imageCountMoreThan, sinceImagePushed ]. The default output has a rule_priority $${rule_priority} which can be interpreted by a data "template_file" in a different module. If needed the rule_priority can be overridden.

Examples

Rotate after 30 images exist for ["test","uat","prod"]

module "ecr_lifecycle_rule_tagged_image_count_30" {
  source = "doingcloudright/ecr-lifecycle-policy-rule/aws"

  tag_status = "tagged"
  count_type = "imageCountMoreThan"
  prefixes  = ["test","uat","prod"]
  count_number = 30
}

output "ecr_lifecycle_rule_tagged_image_count_30" {
  value = "${module.ecr_lifecycle_rule_tagged_image_count_30.policy_rule}"
}

Rotate images after 40 days since image pushed for ["test","uat","prod"]

module "ecr_lifecycle_rule_tagged_40_days_since_image_pushed" {
  source = "doingcloudright/ecr-lifecycle-policy-rule/aws"

  tag_status = "tagged"
  count_type = "sinceImagePushed"
  count_number = 40
  prefixes  = ["test","uat","prod"]
}

output "ecr_lifecycle_rule_tagged_40_days_since_image_pushed" {
  value = "${module.ecr_lifecycle_rule_tagged_40_days_since_image_pushed.policy_rule}"
}

Rotate images after 7 images exist for any

module "ecr_lifecycle_rule_any_7_images" {
  source = "doingcloudright/ecr-lifecycle-policy-rule/aws"

  tag_status = "any"
  count_type = "imageCountMoreThan"
  count_number = "7"
}

output "ecr_lifecycle_rule_any_7_images" {
  value = "${module.ecr_lifecycle_rule_any_7_images.policy_rule}"
}

Rotate images after 100 days since image pushed for untagged images

module "ecr_lifecycle_rule_untagged_100_days_since_image_pushed" {
  source = "doingcloudright/ecr-lifecycle-policy-rule/aws"

  tag_status = "untagged"
  count_type = "sinceImagePushed"
  count_number = "100"
}

output "ecr_lifecycle_rule_untagged_100_days_since_image_pushed" {
  value = "${module.ecr_lifecycle_rule_untagged_100_days_since_image_pushed.policy_rule}"
}
