Tests Passed: 9 months ago

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

1variable "vault_token" {
2  type        = string
3  description = "The Vault token to use for authentication."
4  sensitive   = true
5}
6
7module "vault" {
8  source      = "registry.coder.com/modules/vault-token/coder"
9  version     = "1.0.7"
10  agent_id    = coder_agent.example.id
11  vault_token = var.token
12  vault_addr  = "https://vault.example.com"
13}
Copy

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

1vault kv get -namespace=coder -mount=secrets coder
Copy

or using the Vault API:

1curl -H "X-Vault-Token: ${VAULT_TOKEN}" -X GET "${VAULT_ADDR}/v1/coder/secrets/data/coder"
Copy

Configuration

To configure the Vault module, you must create a Vault token with the the required permissions and configure the module with the token and Vault address.

1. Create a vault policy with read access to the secret mount you need your developers to access.

   1vault policy write read-coder-secrets - <<EOF
   2 path "coder/data/*" {
   3   capabilities = ["read"]
   4 }
   5 path "coder/metadata/*" {
   6   capabilities = ["read"]
   7 }
   8 EOF
   Copy

2. Create a token using this policy.

   1vault token create -policy="read-coder-secrets"
   Copy

3. Copy the generated token and use in your template.
