  longDescription: |
    Executes a [Kaniko](https://github.com/GoogleContainerTools/kaniko) build for creating a Docker container.

    ### Building multiple container images

    The step allows you to build multiple container images with one run.
    This is suitable in case you need to create multiple images for one microservice, e.g. for testing.

    All images will get the same "root" name and the same versioning.<br />
    **Thus, this is not suitable to be used for a monorepo approach!** For monorepos you need to use a build tool natively capable to take care for monorepos
    or implement a custom logic and for example execute this `kanikoExecute` step multiple times in your custom pipeline.

    You can activate multiple builds using the parameters

    * [containerMultiImageBuild](#containermultiimagebuild) for activation
    * [containerMultiImageBuildExcludes](#containermultiimagebuildexcludes) for defining excludes
