I encounter on an error patching node in cluster, i setting up three server, they are all master,worker node.
In order to let my ap pods be able to request service, i setup a virtual ip by using keepalived, all request come from this ip to my ap pods.

  • virtualip: 192.168.1.13
  • server1:192.168.1.10
  • server2: 192.168.1.11
  • server3: 192.168.1.12

Below is the error message from the server3.
