【问题描述】：

我尝试使用 openresty:centos 构建一个镜像，并且该镜像已成功构建，但是当尝试使用此镜像运行容器时，容器 STOP ans 显示此消息：

nginx：无效选项：“/bin/sh”

RUN mkdir /home/app

EXPOSE 80

CMD nginx -p /usr/local/openresty/nginx -c nginx.conf

构建镜像的命令：

docker build -t openresty_test .

运行容器的命令：

docker run -it -p 8888:80 --name img_resty openresty_test

回复：

nginx: invalid option: "/bin/sh"

【解决方案1】：

根据Dockerfile，您应该覆盖ENTRYPOINT 而不是CMD。详情请见Docker documentation。

ENTRYPOINT 和 CMD 组合在一起，所以你实际上是在尝试执行：

$ /usr/local/openresty/bin/openresty -g 'daemon off;' /bin/sh -c 'nginx -p /usr/local/openresty/nginx -c nginx.conf'
nginx: invalid option: "/bin/sh"

我还建议您使用CMD/ENTRYPOINT 的执行形式（["executable","param1","param2"]，而不是executable param1 param2）
