I tried looking through the documentation but it is confusing at best and misses important parts at worst.  Is there any place where the entire syntax and ALL options for asset bundle YAMLs are described? 

I found this https://docs.databricks.com/en/dev-tools/bundles/index.html, but aside from rudimentary examples, it is incredibly difficult to figure out what key should be where in the YAML... Sometimes it was easier to check out the Terraform documentation for databricks jobs/tasks and work backwards from there, instead of reading the Databricks documentation. 

I cannot figure out how to use job cluster with custom built whl files. I build one whl file on the fly and pull another as a dependency from a private Pypi server. 

I was able to do it with a general purpose cluster which I created beforehand, but the job cluster never seems to install the libraries.

With a general purpose:

- task_key: ingestion
    existing_cluster_id: ${var.existing_cluster_id}
    python_wheel_task:
        package_name: my_package
        entry_point: my_package_ep
        libraries:
            - whl: ./dist/*.whl
            - pypi:
            package: another-package==1.0.0
            repo: https://pkgs.dev.azure.com/xxxx/xx/_packaging/xxx/pypi/simple/
        

I tried various possibilities where I thought the "libraries" key makes sense, but due to a lack of documentation I was not able to figure it out. Neither below the task, nor in the environment did it work.

      environments:
        - environment_key: myenv
          spec:
            client: "1"
            dependencies:
              - whl: ./dist/*.whl
              - pypi:
                  package: pyspark-framework==${var.pyspark_framework_version}
                  repo: https://pkgs.dev.azure.com/xxx/xxxx/_packaging/xxxx/pypi/simple/

      tasks:
        - task_key: mytask
          environment_key: myenv
          python_wheel_task:
            package_name: mypackage
            entry_point: mypackage_ep
            libraries:
              - whl: ./dist/*.whl
              - pypi:
                  package: pyspark-framework==${var.pyspark_framework_version}
                  repo: https://pkgs.dev.azure.com/xxx/xxxx/_packaging/xxxx/pypi/simple/

Can anyone tell me how to properly add my whl files (local dist + from pypi) to a job_cluster?
