Hashicorp Vault Connection

Learn how to configure a Hashicorp Vault Connection for Infisical.

Infisical is compatible with Vault Self-hosted, HCP Vault Dedicated, and HCP Vault Enterprise deployments. Please note that HCP Generic Secrets are currently not supported.

Infisical supports two methods for connecting to Hashicorp Vault.

App Role (Recommended)

1. Navigate to Vault Access

   

2. Enable New Method

   In the Authentication Methods tab, click on Enable new method.

   

3. Select AppRole

   

4. Enable Method

   You may change the name of the method, but we suggest keeping it as approle.

   

5. Navigate to Vault Policies

   From the home page, navigate to Policies.

   

6. Create ACL Policy

   

7. Create Policy

   You may name your policy whatever you want, but remember the name as it will be used in future steps.

   Depending on your use case, you may have different policy configurations:

   Secret Sync

   path "demo_mount/data/*" {
     capabilities = [ "create", "read", "update" ]
   }
   
   path "sys/mounts" {
     capabilities = ["read"]
   }
   

   • demo_mount: The name of the target secrets engine (e.g., ‘secret’, ‘kv’).
   • data/*: The path within the secrets engine used for storing secrets. The wildcard (*) grants access to all secrets within this mount point.

   Make sure to replace the policy path with the specific path where you intend to sync your secrets. For better security and control, it’s recommended to use a more granular path instead of a wildcard (*). You can also specify a path that doesn’t yet exist—Infisical will automatically create it for you during the sync process.

   

8. Run Shell Commands

   Open Vault Shell

   

   If you used custom approle or policy names in previous steps, you’ll need to customize the following commands.

   Create Infisical Role

   vault write auth/approle/role/infisical token_policies="infisical-policy" token_ttl=30s token_max_ttl=2m
   

   Read RoleID

   vault read auth/approle/role/infisical/role-id
   

   Generate New SecretID

   vault write -force auth/approle/role/infisical/secret-id
   

   Your shell output should look similar to the image below. Save the RoleID and SecretID values for later steps.

   

Getting Vault Instance URL

Self Hosted

For self-hosted instances, locate and copy your vault’s base URL (for example: https://vault.example.com).

Save the URL for later steps.

Setup Vault Connection in Infisical

Infisical UI

1. Navigate to App Connections

   In your Infisical dashboard, navigate to the App Connections page in the desired project.

   

2. Add Connection

   Click the + Add Connection button and select the Hashicorp Vault Connection option.

   

3. Configure Connection

   Configure your Vault Connection using the Instance URL and credentials from the steps above. Depending on if you chose to authenticate with an Access Token or AppRole, you may need to input different information.

   

   App Role

   • Description: An optional description to provide details about this connection.
   • Instance URL: The URL of your Hashicorp Vault instance.
   • Namespace (optional): The namespace within your vault. Self-hosted and enterprise clusters may not use namespaces.
