Hashicorp Vault

This module lets you authenticate with Hashicorp Vault in your Coder workspaces.

Note: This module does not cover setting up and configuring Vault. For that, see the Vault documentation.

module "vault" {
    source = "https://registry.coder.com/modules/vault"
    vault_addr = "https://vault.example.com"
}

Then you can use the Vault CLI in your workspaces to fetch secrets from Vault:

vault kv get secret/my-secret

or using the Vault API:

curl -H "X-Vault-Token: $VAULT_TOKEN" -X GET $VAULT_ADDR/v1/secret/data/my-secret

Configuration

To configure the Vault module, you must setup a Vault OIDC Provider and configure Coder to use it.

OIDC Provider in Vault

1. Create a Vault OIDC Application with name coder and set the Redirect URI to https://coder.example.com/external-auth/vault/callback.

2. MAke note of the Vault OIDC Provider's Client ID and Client Secret.

3. Add a provider to OIDC application with name coder and set the "Issuer URL" to $VAULT_ADDR.

Coder configuration

Add the following to your Coder configuration:

CODER_EXTERNAL_AUTH_0_ID: "vault"
CODER_EXTERNAL_AUTH_0_TYPE: "vault"
CODER_EXTERNAL_AUTH_0_CLIENT_ID: "XXXXXXXXXX"
CODER_EXTERNAL_AUTH_0_CLIENT_SECRET: "XXXXXXXXX"
CODER_EXTERNAL_AUTH_0_DISPLAY_NAME: "Hashicorp Vault"
CODER_EXTERNAL_AUTH_0_DISPLAY_ICON: "/icon/vault.svg"
CODER_EXTERNAL_AUTH_0_VALIDATE_URL: "$VAULT_ADDR/v1/identity/oidc/provider/coder/userinfo"
CODER_EXTERNAL_AUTH_0_AUTH_URL: "$VAULT_ADDR/ui/vault/identity/oidc/provider/coder/authorize"
CODER_EXTERNAL_AUTH_0_TOKEN_URL: "$VAULT_ADDR/v1/identity/oidc/provider/coder/token"
CODER_EXTERNAL_AUTH_0_SCOPES: "openid"

Note: Replace $VAULT_ADDR with your Vault address.

Examples

Configure Vault integration with a custom Vault auth id

module "vault" {
    source = "https://registry.coder.com/modules/vault"
    vault_addr = "https://vault.example.com"
    vault_auth_id = "my-auth-id"
}

Configure Vault integration and install a specific version of the Vault CLI

module "vault" {
    source = "https://registry.coder.com/modules/vault"
    vault_addr = "https://vault.example.com"
    vault_cli_version = "1.15.0"
}
