Changes

Added support for Databricks Apps in DABs.

It's possible to configure new app resource in bundle and point it to the custom source_code_path location where Databricks App code is define. On databricks bundle deploy DABs will create an app and execute app deployment with the pointed files. All consecutive databricks bundle deploy execution will trigger new app deployments.

Here's an example of configuration:

bundle:
  name: apps

variables:
  my_job_id:
    description: "ID of job to run app"
    lookup:
      job: "My Job"
  databricks_name:
    description: "Name for app user"
  additional_flags:
    description: "Additional flags to run command app"
    default: ""
  my_app_config:
    type: complex
    description: "Configuration for my Databricks App"
    default:
      command:
        - flask
        - --app
        - hello
        - run
        - ${var.additional_flags}
      env:
        - name: DATABRICKS_NAME
          value: ${var.databricks_name}

resources:
  apps:
    my_app:
      name: "anester-app" # required and has to be unique
      description: "My App"
      source_code_path: ./app # required and points to location of app code
      config: ${var.my_app_config}
      resources:
        - name: "my-job"
          description: "A job for app to be able to run"
          job:
            id: ${var.my_job_id}
            permission: "CAN_MANAGE_RUN"
      permissions:
        - user_name: "foo@bar.com"
          level: "CAN_VIEW"
        - service_principal_name: "my_sp"
          level: "CAN_MANAGE"

targets:
  dev:
    variables:
      databricks_name: "Andrew (from dev)"
      additional_flags: --debug

  prod:
    variables:
      databricks_name: "Andrew (from prod)"
