我有以下Dockerfile
FROM ubuntu:14.04
EXPOSE 8000
# Install nginx
RUN apt-get update -q \
&& apt-get install --no-install-recommends --no-install-suggests -y -q \
nginx \
&& rm -rf /var/lib/apt/lists/*
COPY ./nginx.conf /etc/nginx/
COPY ./index.html /usr/share/nginx/test/
RUN groupadd -r webgroup \
&& useradd -r -m -g webgroup webuser \
&& touch /run/nginx.pid \
&& chown -R webuser:webgroup /var/log/nginx /var/lib/nginx /run/nginx.pid
USER webuser
CMD nginx
当我运行它时,/var/log/nginx
上的权限被拒绝:
mikhails-mbp:test-docker-nginx mkuleshov$ docker run -p 8000:8000 mytest
nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)
2016/10/02 17:02:51 [emerg] 5#0: open() "/var/log/nginx/access.log" failed (13: Permission denied)
如果我用bash进入容器,我会看到:
webuser@d190146a0e8d:/var/log/nginx$ ls -la
total 8
drwxr-x--- 2 webuser webgroup 4096 Jun 2 15:16 .
drwxrwxr-x 8 root syslog 4096 Oct 2 17:02 ..
怎么可能?在上述会话期间,我也无法在该用户下创建文件。
有帮助的内容:删除/var/log/nginx
并重新创建。但我不知道为什么会这样。
没有SELinux。
有没有人遇到过这样的事情,或者有什么我做错了吗?
P.S。如果docker info
可以帮助

最有可能将您的用户添加到adm组中将解决您的问题。
尝试使用sudo usermod -aG adm webuser
