AWS::ImageBuilder::ImagePipeline Schedule - AWS CloudFormation

AWS::ImageBuilder::ImagePipeline Schedule

A schedule configures when and how often a pipeline will automatically create a new image.


To declare this entity in your AWS CloudFormation template, use the following syntax:


{ "PipelineExecutionStartCondition" : String, "ScheduleExpression" : String }



The condition configures when the pipeline should trigger a new image build. When the pipelineExecutionStartCondition is set to EXPRESSION_MATCH_AND_DEPENDENCY_UPDATES_AVAILABLE, and you use semantic version filters on the base image or components in your image recipe, Image Builder will build a new image only when there are new versions of the image or components in your recipe that match the semantic version filter. When it is set to EXPRESSION_MATCH_ONLY, it will build a new image every time the CRON expression matches the current time. For semantic version syntax, see CreateComponent in the Image Builder API Reference.

The cron expression determines how often EC2 Image Builder evaluates your pipelineExecutionStartCondition.
