ERROR: cannot start nginx as networking would not start on alpine docker image

Question

我们正在尝试在基于 java 的 alpine 映像 (anapsix/alpine-java:7_jdk) 上安装和运行 nginx，但是当我们启动它时遇到以下错误

rc-service nginx start

我们试过很多文章，但没有提到如何解决这个基于 alpine 的图像上的 nginx 网络问题。即使我们创建了 /etc/network/interfaces 文件，我们也不知道里面的正确值应该是什么。下面是我们运行ning Dockerfile

# Add Nginx
RUN apk --update add nginx openrc
RUN mkdir -p /run/nginx
RUN touch /run/nginx/nginx.pid
# RUN adduser -D -g 'nginx' nginx
# RUN mkdir /home/nginx
RUN chown -R nginx:nginx /var/lib/nginx
# RUN chown -R nginx:nginx /home/nginx
COPY birt.conf /etc/nginx/conf.d/birt.conf
# COPY index.html /nginx
RUN openrc
RUN touch /run/openrc/softlevel
RUN rc-update add nginx default

请帮助我们实现这一目标。

看到这个惊人的 answer.

后，我设法让 Nginx 在 anapsix/alpine-java:7_jdk 图像中工作

这是一个有效的 Dockerfile :

FROM anapsix/alpine-java:7_jdk

COPY script.bash .

RUN apk --update add nginx openrc
RUN openrc
RUN touch /run/openrc/softlevel

CMD bash ./script.bash

这里是 CMD 中使用的 script.bash :

#!/bin/bash

# Tell openrc loopback and net are already there, since docker handles the networking
echo 'rc_provide="loopback net"' >> /etc/rc.conf

# get inside the container bash
bash

使用 docker build . -t nginx_alpine_java 运行以下命令构建映像后：

docker run -it -p 80:80 nginx_alpine_java

现在我们在容器内 bash

bash-4.3# rc-service nginx status
 * status: stopped

bash-4.3# rc-service nginx start
 * /run/nginx: creating directory
 * /run/nginx: correcting owner                                [ ok ]
 * Starting nginx ...                                          [ ok ]
