使用kubeadm部署k8s集群07-扩容kube-scheduler到3节点
扩容 kube-scheduler 到 3 节点连接到本节点的 apiserver
# cat /etc/kubernetes/manifests/kube-scheduler.yaml |grep '/etc/kubernetes'
--kubeconfig=/etc/kubernetes/scheduler.conf
mountPath: /etc/kubernetes/scheduler.conf
path: /etc/kubernetes/scheduler.conf
显然，我们需要 2 个配置文件：
/etc/kubernetes/scheduler.conf
/etc/kubernetes/manifests/kube-scheduler.yaml
查看文件内容发现，只有一个配置需要更改 IP 地址指向对应的 apiserver 地址：
/etc/kubernetes/scheduler.conf
# mkdir ~/k8s_install/master/kube-scheduler
# cd !$
修改配置：
# cp -a /etc/kubernetes/scheduler.conf tvm-01.scheduler.conf
# sed -i 's#10.10.9.67:6443#10.10.9.68:6443#' tvm-01.scheduler.conf
同步配置到目标节点来启动服务：
# scp tvm-01.scheduler.conf 10.10.9.68:/etc/kubernetes/scheduler.conf
# scp /etc/kubernetes/manifests/kube-scheduler.yaml 10.10.9.68:/etc/kubernetes/manifests/
检查是否有异常：
# kubectl get pods --all-namespaces |grep 'kube-scheduler-tvm'
# kubectl logs --tail=20 -n kube-system kube-scheduler-tvm-01
在另一个节点操作：
修改配置：
# cp -a /etc/kubernetes/scheduler.conf tvm-02.scheduler.conf
# sed -i 's#10.10.9.67:6443#10.10.9.69:6443#' tvm-02.scheduler.conf
同步配置到目标节点来启动服务：
# scp tvm-02.scheduler.conf 10.10.9.69:/etc/kubernetes/scheduler.conf
# scp /etc/kubernetes/manifests/kube-scheduler.yaml 10.10.9.69:/etc/kubernetes/manifests/
