-This adds a job named `build_job` to the stage `build`. This runner expects a Dockerfile as input, which is specified in the variable `DOCKERFILE`. The resulting container name is specified with the variable `PERSIST_IMAGE_NAME`, which has been defined already above, therefore it does not need to be explicitly mentioned in the `variables` block, again.

+This block defines a test job. The job will be executed by the [.container-runner-eiger-zen2](#container-runner).
 
 This runner will pull the image on the cluster Eiger and run the commands as specified in the `script` tag. In this example we are requesting 2 nodes with 1 task on each node, i.e. 2 tasks total. All [Slurm environment variables](https://slurm.schedmd.com/srun.html#SECTION_INPUT-ENVIRONMENT-VARIABLES) are supported. The commands will be running inside the container specified by the `image` tag.
