Home / Keptn v1 Docs / Release 0.18.x / Operate Keptn / Secret Service
The Secret Service manages secrets in a Keptn Cluster. It provides a simple API for creating, updating or deleting secrets in a specific secret backend such as Kubernetes or vault.
NOTE: The current implementation only supports Kubernetes Secrets as a secret backend.
A secret created by the secret-service is bound to a scope.
A scope contains a set of capabilities which are a set of permissions.
Scopes are hardcoded into a file called
scopes.yaml which is read by the secret-service during startup.
The default scope for Keptn looks like this:
Scopes: keptn-default: Capabilities: keptn-secrets-default-read: Permissions: - get keptn-webhook-service: Capabilities: keptn-webhook-svc-read: Permissions: - get dynatrace-service: Capabilities: keptn-dynatrace-svc-read: Permissions: - get
In Kubernetes, scope maps to a Kubernetes ServiceAccount and a capability maps to a Kubernetes Role.
Based on the
scopes.yaml file above, when a secret with scope
keptn-webhook-service is created, the secret-service does the following:
keptn-webhook-svc-readcontaining rules to access the created secret with permissions
keptn-webhook-service-rolebindingwith subjects set to the ServiceAccount named
Thus, every Kubernetes Pod bound to the service account keptn-webhook-service is able to read the secret.
scopes.yaml must be modified manually in order to add, modify or delete any scopes.
No API endpoint is provided for that.
