linux - 尝试RUN时Openresty Docker容器，返回nginx : invalid option: "/bin/sh"

Question

我尝试使用 openresty:centos 构建一个图像，图像已成功构建，但是当尝试使用此图像运行容器时，容器停止并显示此消息:

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 /usr/local/openresty/luajit/bin/luarocks install lua-resty-jwt
RUN /usr/local/openresty/luajit/bin/luarocks install lua-resty-redis

RUN /usr/local/openresty/luajit/bin/luarocks install luaposix
RUN /usr/local/openresty/luajit/bin/luarocks install uuid

RUN export PATH

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

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"

根据 Dockerfile ，您应该覆盖 ENTRYPOINT 而不是 CMD。参见 Docker documentation了解详情。

ENTRYPOINT 和 CMD 结合在一起，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 exec 形式 (["executable","param1", "param2"]，不是可执行的param1 param2)
