FAQPage Schema
Why is my ExternalSecret not syncing in Kubernetes?▼

Stale ExternalSecret data usually indicates incorrect refresh interval configurations or rotation failures. Diagnose synchronization by verifying refresh intervals, validating provider authentication, and checking SecretStore health to ensure secrets update properly.

How do I troubleshoot ESO provider authentication issues?▼

To troubleshoot ESO provider authentication, verify AWS Secrets Manager, Azure Key Vault, HashiCorp Vault, or GCP Secret Manager credentials and permissions. Apply diagnostic workflows to assess controller health and resolve SecretStore authentication failures.

How do I fix a SecretStore that is failing in Kubernetes?▼

Fix a failing SecretStore by assessing ESO controller health and validating SecretStore or ClusterSecretStore status. Use diagnostic workflows to identify provider authentication errors and data mapping problems to restore synchronization.

Does External Secrets Operator work with HashiCorp Vault and GCP Secret Manager?▼

External Secrets Operator works with HashiCorp Vault, GCP Secret Manager, AWS Secrets Manager, and Azure Key Vault. If sync fails across these providers, use diagnostic workflows to assess data mapping, provider authentication, and SecretStore health.

What should I do when ExternalSecret data is missing or stale?▼

When ExternalSecret data is missing or stale, check refresh intervals and rotation configurations. Diagnose provider authentication and SecretStore health to repair synchronization failures and ensure external secrets map correctly to Kubernetes secrets.
