我们正在尝试在基于 java 的 alpine 镜像上安装并运行 nginx (anapsix/alpine-java:7_jdk
)但是当我们启动它时我们面临以下错误
rc-service nginx start

我们已经尝试了很多文章,但没有提到如何修复这个基于 alpine 的映像上的 nginx 网络问题。即使我们创造/etc/network/interfaces
文件中,我们不知道其中的正确值应该是什么。下面是我们正在运行的 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。
我设法让 Nginx 在其中工作anapsix/alpine-java:7_jdk
看到这个惊人的图像后answer https://github.com/gliderlabs/docker-alpine/issues/42#issuecomment-173825611.
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
这是script.bash
用于CMD
:
#!/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
使用构建图像后docker build . -t nginx_alpine_java
运行以下命令:
docker run -it -p 80:80 nginx_alpine_java
现在我们正在容器狂欢中
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 ]
我希望它能与您合作。
