Kubernetes Scheduler作用是将Controller Manager将要新建的Pod按照特定的调度算法和调度策略绑定到集群中某个合适的Node上，并将绑定信息写入到etcd中。
一、部署Scheduler
下面生成kube-scheduler的kubeconfig文件,操作如下：
cd /etc/kubernetes export KUBE_APISERVER="https://192.168.15.200:6443"
配置 cluster
kubectl config set-cluster kubernetes --certificate-authority=/etc/kubernetes/ssl/ca.pem --embed-certs=true --server=${KUBE_APISERVER} --kubeconfig=scheduler.conf
配置 credentials
kubectl config set-credentials system:kube-scheduler --client-certificate=/etc/kubernetes/ssl/scheduler.pem --embed-certs=true --client-key=/etc/kubernetes/ssl/scheduler-key.pem --kubeconfig=scheduler.conf
配置 context
kubectl config set-context system:kube-scheduler@kubernetes --cluster=kubernetes --user=system:kube-scheduler --kubeconfig=scheduler.conf
配置 default context
kubectl config use-context system:kube-scheduler@kubernetes --kubeconfig=scheduler.conf
将生成的scheduler.conf文件分发到各个 Master 节点的 /etc/kubernetes 目录下，如下：
scp scheduler.conf k8s-master02:/etc/kubernetes/ scp scheduler.conf k8s-master03:/etc/kubernetes/
创建 kube-scheduler 的 systemd服务启动文件，如下：
export KUBE_APISERVER="https://192.168.15.200:6443" cat > /usr/lib/systemd/system/kube-scheduler.service <<EOF [Unit] Description=kube-scheduler After=network.target After=kube-apiserver.service [Service] EnvironmentFile=-/etc/kubernetes/scheduler ExecStart=/usr/local/bin/kube-scheduler --logtostderr=true --v=0 --master=${KUBE_APISERVER} --kubeconfig=/etc/kubernetes/scheduler.conf --leader-elect=true Restart=on-failure Type=simple LimitNOFILE=65536 [Install] WantedBy=multi-user.target EOF
分发到其他主机：
scp /usr/lib/systemd/system/kube-scheduler.service k8s-master02:/usr/lib/systemd/system/ scp /usr/lib/systemd/system/kube-scheduler.service k8s-master03:/usr/lib/systemd/system/
在各节点启动服务：
systemctl daemon-reload systemctl enable kube-scheduler systemctl start kube-scheduler systemctl status kube-scheduler
三个 Master 节点上的 kube-schedule 部署完成，通过选举出一个 leader 工作。
查看 Kubernetes Master 集群各个核心组件的状态全部正常，如下所示：
[root@k8s-master01 kubernetes]# kubectl get cs NAME STATUS MESSAGE ERROR etcd-1 Healthy {"health": "true"} scheduler Healthy ok controller-manager Healthy ok etcd-0 Healthy {"health": "true"} etcd-2 Healthy {"health": "true"}
kubernetes Master部署之Scheduler 以及 HA部署(5)
