GCP Secrets Manager
The current version of Kong Gateway’s implementation supports
GCP Secrets Manager in two
- Environment variables
- Workload Identity
To configure GCP Secrets Manager, the
environment variable must be set to the JSON document referring to the
credentials for your service account:
export GCP_SERVICE_ACCOUNT=$(cat gcp-my-project-c61f2411f321.json)
Kong Gateway uses the key to automatically authenticate
with the GCP API and grant you access.
To use GCP Secrets Manager with
on a GKE cluster, update your pod spec so that the service account is
attached to the pod. For configuration information, read the Workload

When you use the Vault entity, you no longer need to specify the GCP project ID to access the secrets.
