Kubernetes Test Automation: Implementing a Shift-Left Strategy

The FAQ section in your document addresses several critical aspects of managing ephemeral Kubernetes environments for testing purposes. Here's an enhanced version with additional context and solutions:

How do I handle secret management in ephemeral environments?

Answer: Don't store secrets directly within your Git repository, even for test environments. Instead, use a dedicated secrets management tool like HashiCorp Vault or AWS Secrets Manager to securely manage and retrieve secrets.

• HashiCorp Vault: Use the External Secrets Operator (ESO) to fetch secrets from Vault based on environment variables or annotations.

  • Define a SecretStore at the cluster level pointing to your Vault instance.
  • Each ephemeral namespace gets an ExternalSecret object that retrieves necessary keys based on the PR number or a generic "test" profile.

• AWS Secrets Manager: Similar approach using ESO, where secrets are fetched from AWS Secrets Manager instead of Vault.

Example:

yaml
 
1apiVersion: external-secrets.io/v1beta1
2kind: ExternalSecret
3metadata:
4  name: test-secret
5spec:
6  secretStoreRef:
7    kind: SecretStore
8    name: vault-store
9  refreshInterval: "30s"
10  resourceFetch:
