LifecycleRule

class aws_cdk.aws_ecr.LifecycleRule(*, description=None, max_image_age=None, max_image_count=None, rule_priority=None, tag_pattern_list=None, tag_prefix_list=None, tag_status=None)

Bases: object

An ECR life cycle rule.

Parameters:

description (Optional[str]) – Describes the purpose of the rule. Default: No description
max_image_age (Optional[Duration]) – The maximum age of images to retain. The value must represent a number of days. Specify exactly one of maxImageCount and maxImageAge.
max_image_count (Union[int, float, None]) – The maximum number of images to retain. Specify exactly one of maxImageCount and maxImageAge.
rule_priority (Union[int, float, None]) – Controls the order in which rules are evaluated (low to high). All rules must have a unique priority, where lower numbers have higher precedence. The first rule that matches is applied to an image. There can only be one rule with a tagStatus of Any, and it must have the highest rulePriority. All rules without a specified priority will have incrementing priorities automatically assigned to them, higher than any rules that DO have priorities. Default: Automatically assigned
tag_pattern_list (Optional[Sequence[str]]) – Select images that have ALL the given patterns in their tag. There is a maximum limit of four wildcards (*) per string. For example, [”test*1*2*3”, “test*1*2*3”] is valid but [“test*1*2*3*4*5*6”] is invalid. Both tagPrefixList and tagPatternList cannot be specified together in a rule. Only if tagStatus == TagStatus.Tagged
tag_prefix_list (Optional[Sequence[str]]) – Select images that have ALL the given prefixes in their tag. Both tagPrefixList and tagPatternList cannot be specified together in a rule. Only if tagStatus == TagStatus.Tagged
tag_status (Optional[TagStatus]) – Select images based on tags. Only one rule is allowed to select untagged images, and it must have the highest rulePriority. Default: TagStatus.Tagged if tagPrefixList or tagPatternList is given, TagStatus.Any otherwise
