External Secrets Integration
External Secrets Operator is a Kubernetes controller that syncs secrets from external vaults into K8s. Instead of managing secrets in etcd (insecure), you store them in Vault or cloud KMS, and External Secrets mirrors them as Kubernetes Secret objects. Automatic rotation, audit logs, and centralized access control. Senior engineers earn 20-30% premium because they design for zero-downtime rotation and multi-region failover. Learning takes 3-4 weeks. The skill is essential for regulated industries (fintech, healthcare) where secret rotation is mandatory.
External Secrets Integration이란
External Secrets Operator (ESO) is a Kubernetes controller that syncs secrets from external secret management systems (Vault, AWS Secrets Manager, Azure Key Vault) into Kubernetes Secret objects. Instead of storing database passwords, API keys, and certificates directly in K8s etcd (which is insecure), you store them in a purpose-built vault, and ESO automatically mirrors them into K8s. When the secret rotates (e.g., database password changes), ESO detects the change and updates the K8s Secret. Applications read from K8s Secrets as usual, but the underlying credential comes from an audited, encrypted vault.
