Pulumi ESC

Sync environments, configs and secrets from Pulumi ESC to Kubernetes using the External Secrets Operator.

Authentication

Pulumi Access Tokens are recommended to access Pulumi ESC.

Creating a SecretStore

A Pulumi SecretStore can be created by specifying the organization and environment and referencing a Kubernetes secret containing the accessToken.

apiVersion: external-secrets.io/v1beta1
kind: SecretStore
metadata:
  name: secret-store
spec:
  provider:
    pulumi:
      organization: <NAME_OF_THE_ORGANIZATION>
      environment: <NAME_OF_THE_ENVIRONMENT>
      accessToken:
        secretRef:
          name: <NAME_OF_KUBE_SECRET>
          key: <KEY_IN_KUBE_SECRET>

If required, the API URL (apiUrl) can be customized as well. If not specified, the default value is https://api.pulumi.com.

Referencing Secrets

Secrets can be referenced by defining the key containing the JSON path to the secret. Pulumi ESC secrets are internally organized as a JSON object.

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: secret
spec:
  refreshInterval: 20s
  secretStoreRef:
    kind: SecretStore
    name: secret-store
  data:
  - secretKey: <KEY_IN_KUBE_SECRET>
    remoteRef:
      key: <PULUMI_PATH_SYNTAX>

Note: key is not following the JSON Path syntax, but rather the Pulumi path syntax.
