The full source code, JSON request, and YAML files are available in my Github repository. Hopefully, support for Python 3 (this code is based on Python 3) will become available in the near term. Python support for Azure automation is now generally available, though it’s just Python 2. The Python code can also be adapted to work within an Azure Automation Account Python runbook. I aim to continue expanding and updating this script to serve multiple use cases as they arise. bug("Exception occured with create_job:", exc_info = True)

Json_request = json.load(json_request_file)ĭef create_cluster_req(api_endpoint,headers_config,data): With open(json_request_path) as json_request_file: TEMPLATE_PATH = "Workspace-DB50\\databricks_premium_workspaceLab.json"

YAML_VARS_FILE = "Workspace-DB50\\databricks_workspace_vars.yaml" The first function in the Python script read_yaml_vars_file(yaml_file) takes a yaml variable file path as argument, reads the yaml file and returns the required variables and values to be used for authenticating against the designated Azure subscription.įrom import ServicePrincipalCredentialsįrom import ResourceManagementClientįrom .models import DeploymentMode It has come in handy when there’s a need to quickly provision a Databricks workspace environment in Azure for testing, research and Data Exploration. The functions use a number of Azure Python third-party and standard libraries to accomplish these tasks. The following Python functions were developed to enable the automated provision and deployment of an Azure Databricks workspace and Cluster. The first set of tasks to be performed before using Azure Databricks for any kind of Data exploration and machine learning execution is to create a Databricks workspace and Cluster. Azure Databricks is a data analytics and machine learning platform based on Apache Spark.
