Bases:
object
An ECR life cycle rule.
- Parameters:
description (
Optional
[str
]) – Describes the purpose of the rule. Default: No descriptionmax_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 assignedtag_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.Taggedtag_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.Taggedtag_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
