hasDynamicDockerfileSpec
Whether the dockerfileSpec contains directives which are evaluated at pipeline execution time.
Enabling this option will use the assignment configuration ID as the image tag to differentiate the dockerfileSpec for different configurations.
This value should be set to true
if the dockerfileSpec may not be the same across all instances of the stage. One example would be ShellExec, since additional packages are installed via dockerfileSpec, and the additional packages can be specified when the stage is created.
