Terraform을 사용하여 Databricks 작업 영역 관리

  • 아티클

이 문서에서는 Databricks Terraform 공급자를 사용하여 Azure Databricks 작업 영역에서 리소스를 관리하는 방법을 보여 줍니다.

다음 구성은 가장 일반적인 변수, databricks_spark_version, databricks_node_type 및 databricks_current_user 초기화합니다. 

terraform {
  required_providers {
    databricks = {
      source  = "databricks/databricks"
    }
  }
}

provider "databricks" {}

data "databricks_current_user" "me" {}
data "databricks_spark_version" "latest" {}
data "databricks_node_type" "smallest" {
  local_disk = true
}

표준 기능

이러한 리소스에는 관리 권한이 필요하지 않습니다. 더 많은 설명서는 전용 페이지 databricks_secret_scope, databricks_token, databricks_secret, databricks_notebook, databricks_job, databricks_cluster, databricks_cluster_policy, databricks_instance_pool 사용할 수 있습니다.

작업 영역 보안

보안을 관리하려면 관리 권한이 필요합니다. 더 많은 설명서는 전용 페이지 databricks_secret_acl, databricks_group, databricks_user, databricks_group_member, databricks_permissions 사용할 수 있습니다.

resource "databricks_secret_acl" "spectators" {
  principal  = databricks_group.spectators.display_name
  scope      = databricks_secret_scope.this.name
  permission = "READ"
}

resource "databricks_group" "spectators" {
  display_name = "Spectators (by ${data.databricks_current_user.me.alphanumeric})"
}

resource "databricks_user" "dummy" {
  user_name    = "dummy+${data.databricks_current_user.me.alphanumeric}@example.com"
  display_name = "Dummy ${data.databricks_current_user.me.alphanumeric}"
}

resource "databricks_group_member" "a" {
  group_id  = databricks_group.spectators.id
  member_id = databricks_user.dummy.id
}

resource "databricks_permissions" "notebook" {
  notebook_path = databricks_notebook.this.id
  access_control {
    user_name        = databricks_user.dummy.user_name
    permission_level = "CAN_RUN"
  }
  access_control {
    group_name       = databricks_group.spectators.display_name
    permission_level = "CAN_READ"
  }
}

resource "databricks_permissions" "job" {
  job_id = databricks_job.this.id
  access_control {
    user_name        = databricks_user.dummy.user_name
    permission_level = "IS_OWNER"
  }
  access_control {
    group_name       = databricks_group.spectators.display_name
    permission_level = "CAN_MANAGE_RUN"
  }
}

resource "databricks_permissions" "cluster" {
  cluster_id = databricks_cluster.this.id
  access_control {
    user_name        = databricks_user.dummy.user_name
    permission_level = "CAN_RESTART"
  }
  access_control {
    group_name       = databricks_group.spectators.display_name
    permission_level = "CAN_ATTACH_TO"
  }
}

  cluster_policy_id = databricks_cluster_policy.this.id
  access_control {
    group_name       = databricks_group.spectators.display_name
    permission_level = "CAN_USE"
  }
}

resource "databricks_permissions" "pool" {
  instance_pool_id = databricks_instance_pool.smallest_nodes.id
  access_control {
    group_name       = databricks_group.spectators.display_name
    permission_level = "CAN_ATTACH_TO"
  }
}

보관소

기본 설정 및 요구 사항에 따라 다음을 수행할 수 있습니다.

고급 구성

databricks_workspace_conf 및databricks_ip_access_list 리소스에 대한 전용 페이지에서 더 많은 설명서를 사용할 수 있습니다.

data "http" "my" {
  url = "https://ifconfig.me"
}

resource "databricks_workspace_conf" "this" {
  custom_config = {
    "enableIpAccessLists": "true"
  }
}

resource "databricks_ip_access_list" "only_me" {
  label = "only ${data.http.my.body} is allowed to access workspace"
  list_type = "ALLOW"
  ip_addresses = ["${data.http.my.body}/32"]
  depends_on = [databricks_workspace_conf.this]
}
