Amazon cloudformation 如何使用CloudFormation定义ECR生命周期策略
为了限制存储库中图像的数量,我想定义一个生命周期策略。由于所有堆栈都是用CloudFormation定义的,所以我也要定义这个策略Amazon cloudformation 如何使用CloudFormation定义ECR生命周期策略,amazon-cloudformation,amazon-ecr,Amazon Cloudformation,Amazon Ecr,为了限制存储库中图像的数量,我想定义一个生命周期策略。由于所有堆栈都是用CloudFormation定义的,所以我也要定义这个策略 例如,我的策略可以是“仅保留最近的8张图像,无论是否标记” 解决方案非常简单,但由于我找不到任何示例或类似问题(我知道ECR不是主流),让我在这里发布我找到的简单解决方案,它只需要将策略作为JSON插入到CloudFormation定义中: MyRepository: Type: AWS::ECR::Repository Properties: Li
例如,我的策略可以是“仅保留最近的8张图像,无论是否标记” 解决方案非常简单,但由于我找不到任何示例或类似问题(我知道ECR不是主流),让我在这里发布我找到的简单解决方案,它只需要将策略作为JSON插入到CloudFormation定义中:
MyRepository:
Type: AWS::ECR::Repository
Properties:
LifecyclePolicy:
LifecyclePolicyText: |
{
"rules": [
{
"rulePriority": 1,
"description": "Only keep 8 images",
"selection": {
"tagStatus": "any",
"countType": "imageCountMoreThan",
"countNumber": 8
},
"action": { "type": "expire" }
}]
}
当然,这是非常简单的,但这是我要寻找的起点。您还可以定义对您的PolicyText的引用,以及稍后对您的参数的引用。json将您的策略字符串化 它看起来像这样: template.yml
