Updating the HTTPS Certificate for a LoadBalancer Ingress

If the HTTPS certificate for a LoadBalancer ingress is about to expire or has expired, follow the operations provided in this section to update it.

Application Scenarios

Scenario

Description

LoadBalancer Service certificate

To update an HTTPS certificate, create a LoadBalancer Service certificate and select it when modifying the ingress.

Alternatively, modify the certificate on the ELB certificate management page.

TLS certificate

To update an HTTPS certificate, update the target secret in the cluster. CCE will then automatically configure the certificate (starting with k8s_plb_default) on the ELB. The certificate automatically created by CCE cannot be modified or deleted on the ELB.

Procedure for TLS Secret Certificates

  1. Log in to the CCE console and click the cluster name to access the cluster console.
  2. In the navigation pane, choose ConfigMaps and Secrets. In the right pane, click the Secrets tab, find the secret used by the ingress, and click Update.
  3. Modify the certificate file in the secret and click OK to update the secret. CCE will automatically synchronize the certificate to the ELB.

Procedure for LoadBalancer Service Certificates

  1. Log in to the CCE console and click the cluster name to access the cluster console.
  2. In the navigation pane, choose Services & Ingresses. Then, click the Ingresses tab, locate the row containing the target ingress, and choose More > Update in the Operation column.
  3. Set Certificate Source to ELB server certificate, select a new server certificate, and click OK to update the ingress.
