<p>
The condition configures when the pipeline should trigger a new image build. When the
<code>pipelineExecutionStartCondition</code> is set to
<code>EXPRESSION_MATCH_AND_DEPENDENCY_UPDATES_AVAILABLE</code>, 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 to
<code>EXPRESSION_MATCH_ONLY</code>, it will build a new image every time the CRON expression matches the current
time. For semantic version syntax, see <a
href="https://docs.aws.amazon.com/imagebuilder/latest/APIReference/API_CreateComponent.html">CreateComponent</a>
in the <i> EC2 Image Builder API Reference</i>.
