1、build好镜像后，启动容器,容器内使用了supervisord启动多个服务，然后就出现以下错误

2019/03/09 17:33:58 [emerg] 81#0: still could not bind()

容器启动后，进去查看nginx日志发现nginx不断重启，然后就出现以上错误日志了。nginx配置文件daemon off;注释去掉后，再重新启动容器就不会出现上面的错误，这是为什么呢？

supervisor 监控nginx ，写好配置文件之后，发现一直在重启，排查之后发现是命令不对：

command = /usr/local/bin/nginx 这个命令默认是后台启动，但是supervisor不能监控后台程序，所以supervisor就一直执行这个命令。

命令加上-g 'daemon off;'这个参数可解决这问题，这个参数的意思是在前台运行。

command = /usr/local/bin/nginx  -g 'daemon off;'

或直接在nginx.conf配置文件顶部加上

daemon off;
