Databricks Community

Where can I find documentation on how to set cluster settings (e.g., AWS instance type, spot vs on-demand, number of machines) in Databricks Asset Bundle databicks.yaml files? The only documentation I've come across mentions these things indirectly, for example this link.

Here is an example part my DAB that I'm hoping to complete:

resources:
  jobs:
    clicks:
      job_clusters:
        - job_cluster_key: job_cluster
          new_cluster:
            node_type_id: i3.xlarge
            spark_version: 13.3.x-scala2.12

But I'm not sure the names of fields to specify spot vs on demand, number of machines, etc. I'm having a really hard time finding comprehensive documentation on DABs and their options on Google and on this site.

I have faced similar problem while developing CI/CD using DABs for ML Jobs. There is no straight forward documentation listing all the options for DABs(As far as I know). As a workaround you can look at the REST API documentation which has all the options which are available for creating a job. Similar options are available in DABs as well.

You're right, wasn't able to find much either.
What I did was create an all purpose compute and looked at the yaml/json config from the UI and then copied the attributes to my DAB config.
