How Do I Restore a Deleted VPC Endpoint for a Cluster Connected Through a Private Network?

Background

The VPCEP is deleted by mistake in such a cluster, and the cluster becomes abnormal.

Procedure

The VPCEP IP has been configured in proxy-agent. Therefore, you need to specify an available IP when creating a VPCEP.

  1. Log in to the VPCEP console to check whether the VPCEP in the region where UCS is deployed is deleted. If yes, go to the next step.
  2. Log in to the master node of the abnormal cluster.
  3. Query the IP configured in proxy-agent.kubectl get deploy -n kube-system proxy-agent -oyaml | grep -A3 hostAliases

    Command output:
    hostAliases:
    - hostnames:
      - proxyurl.ucs.myhuaweicloud.com
      ip: 10.0.0.182

  4. Create a VPCEP in the region where UCS is located, use the preceding IP address, and click View In-Use IP Address to ensure that this IP is not used by any other VPCEP. If the IP is in use, change the proxy-agent configuration in the cluster. For details, see Changing proxy-agent Configurations.

  5. Click Next and then Submit to create a VPCEP.
  6. Wait for 1 to 3 minutes, go back to the UCS console, and refresh the cluster status.

Changing proxy-agent Configurations

  1. Create a VPCEP in the region where UCS is located.

  2. Click the ID of the newly created VPCEP to view the automatically allocated node IP.

  3. Log in to the master node of the abnormal cluster.
  4. Change the IP address configured in proxy-agent.kubectl edit deploy -n kube-system proxy-agent

    Change the IP address in the hostAliases field.

    hostAliases:
    - hostnames:
      - proxyurl.ucs.myhuaweicloud.com
      ip: 10.0.0.122

    Press Esc, enter :wq, and press Enter.

  5. Wait for 1 to 3 minutes, go back to the UCS console, and refresh the cluster status.
