Added support for Databricks Apps in DABs (#1928) ## Changes Now 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 defined. On `databricks bundle deploy` DABs will create an app. All consecutive `databricks bundle deploy` execution will update an existing app if there are any updated On `databricks bundle run <my_app>` DABs will execute app deployment. If the app is not started yet, it will start the app first. ### Bundle 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)" ``` ### Execution 1. `databricks bundle deploy -t dev` 2. `databricks bundle run my_app -t dev` **If app is started** ``` ✓ Getting the status of the app my-app ✓ App is in RUNNING state ✓ Preparing source code for new app deployment. ✓ Deployment is pending ✓ Starting app with command: flask --app hello run --debug ✓ App started successfully You can access the app at <app-url> ``` **If app is not started** ``` ✓ Getting the status of the app my-app ✓ App is in UNAVAILABLE state ✓ Starting the app my-app ✓ App is starting... .... ✓ App is starting... ✓ App is started! ✓ Preparing source code for new app deployment. ✓ Downloading source code from /Workspace/Users/... ✓ Starting app with command: flask --app hello run --debug ✓ App started successfully You can access the app at <app-url> ``` ## Tests Added unit and config tests + manual test. ``` --- PASS: TestAccDeployBundleWithApp (404.59s) PASS coverage: 36.8% of statements in ./... ok github.com/databricks/cli/internal/bundle 405.035s coverage: 36.8% of statements in ./... ```
