HashiCorp Vault

To incorporate secrets from HashiCorp Vault, you need to create a generic Kubernetes secret that will be used for vault authentication. This involves creating a Kubernetes secret in the specific namespace where your application will be deployed. The secret should store the base64-encoded password or token obtained from vault. To simplify the process, you can utilize the Devtron generic chart. An example yaml is given below:

apiVersion: v1
kind: Secret
type: Opaque
data:
   token: <vault-password>
metadata:
   name: vault-token
   namespace: <namespace>

Note: Please note that you don't need to create the Kubernetes secret every time you create an External Secret for the corresponding namespace.

Once you have created the generic secret, follow these steps in the application's Secrets section:

1. Create a new secret

To add a new secret to the application, go to the App Configuration section of the application. Then, navigate to the left pane and select the Secrets option and click the Add Secret button.

2. Select HashiCorp Vault as the External Secret Operator

After clicking the Add Secret button, select HashiCorp Vault from the dropdown menu for the Data type option. Provide a name for the secret you are creating, and then proceed to configure the external secret as described in the next step.

3. Configure the secret

To configure the external secret that will be fetched from HashiCorp Vault for your application, you will need to provide specific details using the following key-value pairs:

4. Save the secret

After configuring the external secret from HashiCorp Vault, proceed to save the secret by clicking the Save button.

By following the steps mentioned above and configuring these values correctly, you can seamlessly fetch and utilize external secrets from HashiCorp Vault within your application environment by deploying the application.
