Once you have the workspace setup on Azure or AWS, you have to start managing resources within your workpsace. The following configuration blocks initializes ths most common variables, databricks_spark_version, databricks_node_type, and databricks_current_user.
terraform {
required_providers {
databricks = {
source = "databrickslabs/databricks"
version = "0.3.0"

data "databricks_spark_version" "latest" {}
data "databricks_node_type" "smallest" {

}These resources do not require administrative priviliges. More documentation is available at dedicated pages for databricks_secret_scope, databricks_token, databricks_secret, databricks_notebook, databricks_job, databricks_cluster, databricks_cluster_policy, databricks_instance_pool.

}Depending on your preferences and needs, you can
- Manage JAR, Wheel & Egg libraries through databricks_dbfs_file.
- List entries on DBFS with databricks_dbfs_file_paths data source.
- Get contents of small files with databricks_dbfs_file data source.
- Mount your AWS storage using databricks_aws_s3_mount.
- Mount your Azure storage using databricks_azure_adls_gen1_mount, databricks_azure_adls_gen2_mount, databricks_azure_blob_mount.
