Yandex Lockbox

External Secrets Operator integrates with Yandex Lockbox for secret management.

Prerequisites

Authentication

At the moment, authorized key authentication is only supported:

Create a service account in Yandex.Cloud:

yc iam service-account create --name eso-service-account

Create an authorized key for the service account and save it to authorized-key.json file:

yc iam key create \
  --service-account-name eso-service-account \
  --output authorized-key.json

Create a k8s secret containing the authorized key saved above:

kubectl create secret generic yc-auth --from-file=authorized-key=authorized-key.json

Create a SecretStore pointing to yc-auth k8s secret:

apiVersion: external-secrets.io/v1beta1
kind: SecretStore
metadata:
  name: secret-store
spec:
  provider:
    yandexlockbox:
      auth:
        authorizedKeySecretRef:
          name: yc-auth
          key: authorized-key

NOTE: In case of a ClusterSecretStore, Be sure to provide namespace in all authorizedKeySecretRef with the namespace where the secret resides.

Creating external secret

To make External Secrets Operator sync a k8s secret with a Lockbox secret:

Create a Lockbox secret, if not already created:

yc lockbox secret create \
  --name lockbox-secret \
  --payload '[{"key": "password","textValue": "p@$$w0rd"}]'

Assign the lockbox.payloadViewer role for accessing the lockbox-secret payload to the service account used for authentication:

yc lockbox secret add-access-binding \
  --name lockbox-secret \
  --service-account-name eso-service-account \
  --role lockbox.payloadViewer

Run the following command to ensure that the correct access binding has been added:

yc lockbox secret list-access-bindings --name lockbox-secret

Create an ExternalSecret pointing to secret-store and lockbox-secret:

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: external-secret
spec:
  refreshInterval: 1h
  secretStoreRef:
    name: secret-store
    kind: SecretStore
  target:
    name: k8s-secret # the target k8s secret name
  data:
  - secretKey: password # the target k8s secret key
    remoteRef:
      key: ***** # ID of lockbox-secret
      property: password # (optional) payload entry key of lockbox-secret

The operator will fetch the Yandex Lockbox secret and inject it as a Kind=Secret

kubectl get secret k8s-secret -n <namespace> | -o jsonpath='{.data.password}' | base64 -d
