Sealed Secrets

About​

Bitnami Sealed Secrets is a controller that allows you to encrypt your kubernetes secrets and store them in a secure manner, even in public repositories. The controller works by encrypting your secret into a SealedSecret, which can only be decrypted by the sealed secrets controller in your cluster.

You can use your certificates for the disaster recovery purpose. Please make sure to download encryption keys.

While the controller generates its own certificates upon deployment, you also have the option to bring your own certificates. This allows the controller to consume certificates from a secret labeled with sealedsecrets.bitnami.com/sealed-secrets-key=active. The Secret should reside in the sealed-secrets namespace, which must be the same as the controller's namespace. You can have multiple secrets with this label.

To configure BYO certificates, add the following to the values.yaml:

apps:
  sealed-secrets:
    enabled: true
bootstrap:
  apiVersion: v1
  items:
    - apiVersion: v1
      data:
        tls.crt: <tls-crt>
        tls.key: <tls-key>
      kind: Secret
      metadata:
        generateName: sealed-secrets-key
        labels:
          sealedsecrets.bitnami.com/sealed-secrets-key: active
        name: <sealed-secrets-name>
        namespace: sealed-secrets
      type: kubernetes.io/tls
  kind: List

Make sure to replace <tls-crt>, <tls-key>, <sealed-secrets-name> with your actual certificate data and sealed secrets name.
