# Setting up the Provider
variable "bw_password" {
  type        = string
  description = "Bitwarden Master Key"
  sensitive   = true
}

variable "bw_client_id" {
  type        = string
  description = "Bitwarden Client ID"
  sensitive   = true
}

variable "bw_client_secret" {
  type        = string
  description = "Bitwarden Client Secret"
  sensitive   = true
}

terraform {
  required_providers {
    bitwarden = {
      source  = "maxlaverse/bitwarden"
      version = ">= 0.5.0"
    }
  }
}

provider "bitwarden" {
  master_password = var.bw_password
  client_id       = var.bw_client_id
  client_secret   = var.bw_client_secret
  email           = "test@laverse.net"
  server          = "https://vault.bitwarden.com"
}


# Managing Folders

  name = "My Cloud Credentials"
}


# Managing Logins and Secure Notes

  length           = 16
  special          = true
  override_special = "!#$%&*()-_=+[]{}<>:?"

  name      = "VPN Read Only User/Password Access"
  username  = "vpn-user"
  password  = random_password.vpn_password.result
}

  folder_id = bitwarden_folder.cloud_credentials.id

  name      = "Notes on the preshared Secret"
  notes     = "It's 1234"
}


# Managing Attachments
resource "bitwarden_attachment" "vpn_config" {
  file = "./vpn_config.txt"
  item_id = bitwarden_item_login.vpn_note.id
}


# Using Login information
data "bitwarden_item_login" "mysql_credentials" {

}

  }

  data = {
    username = data.bitwarden_item_login.mysql_root_credentials.username
    password = data.bitwarden_item_login.mysql_root_credentials.password
  }
}


# Using Attachments
data "bitwarden_attachment" "ssh_credentials" {
  id = "4d6a41364d6a4dea8ddb1a"
  item_id = "59575167-4d36-5a58-466e-d9021926df8a"
}

resource "kubernetes_secret" "ssh" {
  metadata {
    name = "ssh"
  }

  data = {
    "private.key" = data.bitwarden_attachment.ssh_credentials.content
  }
}

Security Considerations

The Terraform Bitwarden provider entirely relies on the Bitwarden CLI to interact with Vaults. When you ask Terraform to plan or apply changes, the provider downloads the encrypted Vault locally as if you would use the Bitwarden CLI directly. Currently, the Terraform SDK doesn't offer a way to remove the encrypted Vault once changes have been applied. The issue hashicorp/terraform-plugin-sdk#63 tracks discussions for adding such a feature.

If you want find out more about this file, you can read Terraform's documentation on Data Storage. Please note that this file is stored at <your-project>/.bitwarden/ by default, in order to not interfer with your local Vaults.

Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (see Requirements above).

To compile the provider, run go install. This will build the provider and put the provider binary in the $GOPATH/bin directory.

To generate or update documentation, run go generate.

In order to run the full suite of Acceptance tests, start a Vaultwarden server:

$ docker run -ti \
  -e I_REALLY_WANT_VOLATILE_STORAGE=true \
  -e ADMIN_TOKEN=test1234 \
  -e LOGIN_RATELIMIT_SECONDS=1 \
  -e LOGIN_RATELIMIT_MAX_BURST=1000000 \
  -e ADMIN_RATELIMIT_SECONDS=1 \
  -e ADMIN_RATELIMIT_MAX_BURST=1000000 \
  -p 8080:80 vaultwarden/server

Then run make testacc.

$ make testacc
