We are using Kubernetes version 1.18 with a executable binary of kube-scheduler, how to replace the default scheduler with the scheduler-plugins image

[yauldmar]

We deployed kube-scheduler like this:

vim /etc/systemd/system/kube-scheduler.service
[Unit]
Description=Kubernetes Scheduler Documentation=https://github.com/GoogleCloudPlatform/kubernetes After=kube-apiserver.service
Requires=kube-apiserver.service
[Service] ExecStart=/opt/kube/bin/kube-scheduler
--bind-address=XX.XX.XX.XX \
--master=http://XX.XX.XX.XX:xxxx \
--leader-elect=true
--logtostderr=false
--alsologtostderr=true \ --log-dir=/var/log/kubernetes \ --v=1
Restart=on-failure LimitNOFILE=65536
[Install] WantedBy=multi-user.target

then

systemctl start kube-scheduler

This repo's release only contain images. If you run scheduler as systemd service, you'd need to build the binary (via make build-scheduler), and put it in /opt/kube/bin/kube-scheduler and finally sudo systemctl restart kube-scheduler. (⚠️ ensure the original kube-scheduler binary is backed up)
