Kubernetes集群调度之Scheduler

部署

添加服务启动脚本

[root@lab-26 ctchat]# vi /opt/kubernetes/server/bin/kube-scheduler.sh

#!/bin/sh
./kube-scheduler \
  --leader-elect  \
  --log-dir /data/logs/kubernetes/kube-scheduler \
  --master http://127.0.0.1:8080 \
  --v 2

[root@lab-26 ctchat]# chmod +x /opt/kubernetes/server/bin/kube-scheduler.sh
[root@lab-26 ctchat]# mkdir -p /data/logs/kubernetes/kube-scheduler

使用supervisor服务管理

[root@lab-26 ctchat]# supervisorctl update
kube-scheduler-152-106: added process group
[root@lab-26 ctchat]# ln -s /opt/kubernetes/server/bin/kubectl /usr/bin/kubectl

至此该服务部署完毕。
