Schedule
A schedule configures when and how often a pipeline will automatically create a new image.
Contents
- pipelineExecutionStartCondition
-
The condition configures when the pipeline should trigger a new image build. When the
pipelineExecutionStartCondition
is set toEXPRESSION_MATCH_AND_DEPENDENCY_UPDATES_AVAILABLE
, and you use semantic version filters on the base image or components in your image recipe, EC2 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 toEXPRESSION_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 EC2 Image Builder API Reference.Type: String
