尝试运行时，Openresty Docker容器返回nginx：无效选项：“ / bin / sh”

Question

我尝试使用openresty：centos构建一个imagen，并且该imagen已成功构建，但是当您尝试使用此图像运行一个容器时，容器STOP ans显示以下消息：

nginx：无效选项：“ / bin / sh”

FROM openresty/openresty:1.11.2.3-centos

RUN yum install openssl-devel -y

RUN /usr/local/openresty/luajit/bin/luarocks install lua-cjson

RUN mkdir /home/app

COPY ./src/api-gw/api-gw.lua /home/app

EXPOSE 80

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

用于生成映像的命令：

docker build -t openresty_test .

运行容器的命令：

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

响应：

nginx: invalid option: "/bin/sh"

Answer 1

根据Dockerfile ，您应该覆盖ENTRYPOINT而不是CMD 。 有关详细信息，请参见Docker文档 。

ENTRYPOINT和CMD相结合，因此您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"

我也建议您使用CMD / ENTRYPOINT exec形式 （ ["executable","param1","param2"] ，而不是executable param1 param2 ）
