Mitigation of Incidents due to Expiration of Secrets in MACH Ecosystems: Zero-Downtime Rotation with cert-manager and Vault
Last quarter, a global composable commerce platform experienced a 42-minute outage in its API Gateways layer. The cause was not a database crash or a volumetric denial-of-service attack, but rather a self-signed TLS certificate that quietly expired on a peripheral Kubernetes cluster. Despite having monitoring tools, the teams were unaware of the issue until the outage occurred.
A global commerce platform experienced a 42-minute outage due to an expired TLS certificate in a peripheral Kubernetes cluster. The incident highlighted the risks of manual certificate management and static secret storage. To address this, the integration of cert-manager and HashiCorp Vault can automate certificate issuance, validation, and rotation without human intervention.
This approach enables a dynamic issuance and rotation chain of trust in a multi-tenant environment, eliminating the need for static access tokens and reducing downtime.
