1.本节架构
| 主机名 | ip | 角色 |
|---|---|---|
| hdss7-21.host.com | 10.4.7.21 | kube-schedular |
| hdss7-22.host.com | 10.4.7.22 | kube-schedular |
2.创建启动脚本
cat > /opt/kubernetes/server/bin/kube-scheduler.sh <<'eof'
#!/bin/sh
./kube-scheduler \
--leader-elect \
--log-dir /data/logs/kubernetes/kube-scheduler \
--master http://127.0.0.1:8080 \
--v 2
eof
chmod +x /opt/kubernetes/server/bin/kube-scheduler.sh
mkdir -p /data/logs/kubernetes/kube-scheduler
3.创建supervisor配置
cat > /etc/supervisord.d/kube-scheduler.ini <<'eof'
[program:kube-scheduler-7-21]
command=/opt/kubernetes/server/bin/kube-scheduler.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-scheduler/scheduler.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
注：不同的是[program:kube-scheduler-7-21]
4.启动服务并检查
supervisorctl update
supervisorctl status
etcd-server-7-21 RUNNING pid 12115, uptime 12:52:08
kube-apiserver-7-21 RUNNING pid 12981, uptime 1:27:27
kube-scheduler-7-21 RUNNING pid 14276, uptime 0:02:10
netstat -tulnp | grep kube-sch
