1.本节架构
| 主机名 | IP | 角色 | 节点 |
|---|---|---|---|
| hdss7-21.host.com | 10.4.7.21 | controller-manager | master |
| hdss7-22.host.com | 10.4.7.22 | controller-manager | master |
部署方法以hdss7-21.host.com为例，hdss7-22部署方法类似
2.创建启动脚本
cat > /opt/kubernetes/server/bin/kube-controller-manager.sh <<'eof'
#!/bin/sh
./kube-controller-manager \
--cluster-cidr 172.7.0.0/16 \
--leader-elect \
--log-dir /data/logs/kubernetes/kube-controller-manager \
--master http://127.0.0.1:8080 \
--service-account-private-key-file ./certs/ca-key.pem \
--service-cluster-ip-range 192.168.0.0/16 \
--root-ca-file ./certs/ca.pem \
--v 2
eof
chmod +x /opt/kubernetes/server/bin/kube-controller-manager.sh
mkdir -p /data/logs/kubernetes/kube-controller-manager
3.创建supervisor配置
cat > /etc/supervisord.d/kube-conntroller-manager.ini <<'eof'
[program:kube-controller-manager-7-21]
command=/opt/kubernetes/server/bin/kube-controller-manager.sh ; the program (relative uses PATH, can take args)
numprocs=1 ; number of processes copies to start (def 1)
directory=/opt/kubernetes/server/bin ; directory to cwd to before exec (def no cwd)
autostart=true ; start at supervisord start (default: true)
autorestart=true ; retstart at unexpected quit (default: true)
startsecs=30 ; number of secs prog must stay running (def. 1)
startretries=3 ; max # of serial start failures (default 3)
exitcodes=0,2 ; 'expected' exit codes for process (default 0,2)
stopsignal=QUIT ; signal used to kill process (default TERM)
stopwaitsecs=10 ; max num secs to wait b4 SIGKILL (default 10)
user=root ; setuid to this UNIX account to run the program
redirect_stderr=true ; redirect proc stderr to stdout (default false)
stdout_logfile=/data/logs/kubernetes/kube-controller-manager/controller.stdout.log ; stderr log path, NONE for none; default AUTO
stdout_logfile_maxbytes=64MB ; max # logfile bytes b4 rotation (default 50MB)
stdout_logfile_backups=4 ; # of stdout logfile backups (default 10)
stdout_capture_maxbytes=1MB ; number of bytes in 'capturemode' (default 0)
stdout_events_enabled=false ; emit events on stdout writes (default false)
eof
4.启动服务并检查
supervisorctl update
supervisorctl status
etcd-server-7-22 RUNNING pid 14199, uptime 0:10:55
kube-apiserver-7-22 RUNNING pid 14198, uptime 0:10:55
kube-controller-manager-7-22 RUNNING pid 14357, uptime 0:00:38
kube-scheduler-7-22 RUNNING pid 14197, uptime 0:10:55
netstat -tulnp | grep kube-controller
tcp6 0 0 :::10252 :::* LISTEN 14757/./kube-contro
tcp6 0 0 :::10257 :::* LISTEN 14757/./kube-contro
5.检查master节点
ln -s /opt/kubernetes/server/bin/kubectl /usr/bin/kubectl
kubectl get cs
Warning: v1 ComponentStatus is deprecated in v1.19+
NAME STATUS MESSAGE ERROR
controller-manager Healthy ok
scheduler Healthy ok
etcd-0 Healthy {"health": "true"}
etcd-2 Healthy {"health": "true"}
etcd-1 Healthy {"health": "true"}
