Scheduling containers¶

The compose-config.yaml script is a manifest that describes how the workload container(s) should be scheduled (to the machine cluster described by cluster-config.yaml.) This is the standard docker-compose script.

You can choose to write compose-config.yaml in any of the following formats: - compose-config.yaml: For simple workloads, you can directly write the docker-compose script.
- compose-config.yaml.m4: Use the .m4 template to add conditional statements in the docker-compose script.
- compose-config.yaml.j2: Use the .j2 template to add conditional statements in the docker-compose script.

Image Name¶

The container image in compose-config.yaml should use the full name in the format of <REGISTRY><image-name><RELEASE>, where <REGISTRY> is the docker registry URL (if any) and the <RELEASE> is the release version, (or :latest if not defined.)

If you use the .m4 template, the IMAGENAME macro can expand an image name to include the registry and release information:

include(config.m4)
...
services:
  dummy-benchmark:
    image: IMAGENAME(Dockerfile)
...

where dummy-benchmark must match what defined in JOB_FILTER.

If you use the .j2 template, you must write the image name as follows:

...
services:
  dummy-benchmark:
    image: "{{ RELEASE }}dummy{{ RELEASE }}"
...
