End to end workspace management |
Once you have the workspace setup on Azure or AWS, you have to start managing resources within your workspace. The following configuration blocks initializes the most common variables, databricks_spark_version, databricks_node_type, and databricks_current_user.
terraform {
required_providers {
databricks = {
source = "databrickslabs/databricks"
version = "0.4.5"

data "databricks_current_user" "me" {}
data "databricks_spark_version" "latest" {}
data "databricks_node_type" "smallest" {
local_disk = true
}
These resources do not require administrative privileges. 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 storage using databricks_mount resource.
