Since THPA comprises of 2 components custom kube-controller-manager and scheduler-extender so
|
|
|
|
|
we need to modify these:
|
|
|
|

|
|
|
*** Collecting nodes traffic ***
|
|
|
|
|
|
|
|
|
|
- Copy kube-proxy binary file in kube-proxy directory to /usr/local/bin/ in kube-proxy container running on each node and then reset it.
|
|
|
|
|
|
|
|
|
|
- Check that enpoint is created on each node whenever new deployment is created to make sure we configure correctly.
|
|
|

|
|
|
*** set nodes label ***
|
|
|
|
|
|
|
|
|
|
- For worker nodes, set the following label to them: node-role.kubernetes.io/worker=true
|
|
|
|
|
|
|
|
|
|
*** kube-controller-manager ***
|
|
|
|
|
|
|
|
|
|
- cd to kube-controller-manager directory.
|
|
|
|
|
|
2022-08-22 09:09:24 +00:00
|
|
|
- Unzip and copy binary file "kube-controller-manager" to home directory.
|
2022-08-22 07:15:23 +00:00
|
|
|
|
|
|
|
|
- Copy kube-controller-manager.yaml to /etc/kubernetes/manifests/
|
|
|
|
|
|
|
|
|
|
- After copying, the kube-controller-manager pod will automatically be restarted.
|
|
|
|
|
|
|
|
|
|
*** scheduler-extender ***
|
|
|
|
|
|
|
|
|
|
- cd to scheduler-extender directory
|
|
|
|
|
|
|
|
|
|
- copy files "scheduler-extender-config.yaml" and "scheduler-extender-policy.json" to /etc/kubernetes/
|
|
|
|
|
|
|
|
|
|
- copy file "kube-scheduler.yaml" to /etc/kubernetes/manifests/
|
|
|
|
|
|
|
|
|
|
- cd to k8s-scheduler-extender directory
|
|
|
|
|
|
|
|
|
|
- execute "go build ."
|
|
|
|
|
|
|
|
|
|
- Run the executable file because the scheduler extender run as a server that is triggered whenever new pod need to be scheduled.
