3.4. controller-manager 安装

controller-manager 涉及的服务器：hdss7-21，hdss7-22
controller-manager 设置为只调用当前机器的 apiserver，走127.0.0.1网卡，因此不配制SSL证书

  1. [root@hdss7-21 ~]# vim /opt/kubernetes/server/bin/kube-controller-manager-startup.sh
  2. #!/bin/sh
  3. WORK_DIR=$(dirname $(readlink -f $0))
  4. [ $? -eq 0 ] && cd $WORK_DIR || exit
  6. /opt/kubernetes/server/bin/kube-controller-manager \
  7.     --cluster-cidr 172.7.0.0/16 \
  8.     --leader-elect true \
  9.     --log-dir /data/logs/kubernetes/kube-controller-manager \
  10.     --master http://127.0.0.1:8080 \
  11.     --service-account-private-key-file ./certs/ca-key.pem \
  12.     --service-cluster-ip-range 192.168.0.0/16 \
  13.     --root-ca-file ./certs/ca.pem \
  14.     --v 2
  15. [root@hdss7-21 ~]# chmod u+x /opt/kubernetes/server/bin/kube-controller-manager-startup.sh
  16. [root@hdss7-21 ~]# mkdir -p /data/logs/kubernetes/kube-controller-manager
[root@hdss7-21 ~]# vim /etc/supervisord.d/kube-controller-manager.ini
