AWS Secrets Manager

Prerequisite

Install External Secret Operator (ESO).

To add secrets from AWS Secrets Manager, we need to create a generic Kubernetes secret for AWS authentication.

Create a Kubernetes secret in the namespace in which the application is to be deployed using base64 encoded AWS access-key and secret-access-key. You can use a Devtron generic chart for it.

Note: You don't have to create the Kubernetes secret every time you create external secret for the respective namespace.

Figure 1: Create Kubernetes Secret for AWS Authentication

After creating the generic secret, navigate to Secrets section of the application and follow the steps mentioned below :

  1. Click Add Secret to add a new secret

    Figure 2: Add a New Secret

  2. Select AWS Secret Manager under External Secret Operator (ESO) from the dropdown of Data type

ESO AWS secrets Manager Setup with Devtron using ClusterSecretsStore​

ClusterSecretStore provides a secure and centralized storage solution for managing and accessing sensitive information, such as passwords, API keys, certificates, and other credentials, within a cluster or application environment.

Requirement: Devtron deployment template chart version should be 4.17 and above.

To setup ESO AWS secrets manager with Devtron using ClusterSecretsStore, follow the mentined steps:

1. Create a secret for AWS authentication

Create a Kubernetes secret in any namespace using base64 encoded AWS access-key and secret-access-key. You can use the devtron generic chart for this.

Figure 6: Use Generic Chart

2. Create a ClusterSecretStore

Create a ClusterSecretStore using the secret created for AWS authentication in step 1.

Figure 7: Create ClusterSecretStore

3. Create a secret in the application using ESO AWS Secrets Manager

Go to the application where you want to create an external secret. Navigate to secrets section under application configuration and create a secret using ESO AWS Secrets Manager.
