Hi Guy,
May I ask that does Kubernetes can migrate the pod to other node server?
[root@m11 ~]# kubectl get pod -o wide | grep ldap
ldap-0 3/3 Running 3 4d 10.129.3.119 n13
ldap-1 3/3 Running 3 4d 10.130.3.1 n12

Let say ldap-0 to n11 node computer?

Regards
Thanks…KEN

If you want it on a specific node, you can set pod.spec.nodeName yourself, or use a node label selector.

If you just want it rescheduled, just delete the pod (assuming it has a deployment controller or something like that).

You’re on the right track, but you can’t modify pods themselves - you
have to modify whatever workload controller owns them. For example,
if they were run by a Deployment or something, you can modify that
template, which will cause the pods to be re-deployed.

Now, one might ask WHY you want to bind them to a specific host…

Hi thockin,
It is because the kubernets networking issue in my end, as the container running on compute node 1 seems have network issue, so I try to migrate the container to compute node 2 for testing, but finally it seems same issue even moved to node 2.
