我正在尝试从Nginx加载默认网页,但在容器运行后,我无法通过http连接到端口80.
我正在运行docker 1.9.9
我采取的步骤如下：
我创建了一个Docker文件：
FROM ubuntu:15.10
RUN echo "Europe/London" > /etc/timezone
RUN dpkg-reconfigure -f noninteractive tzdata
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update
RUN apt-get install -y Nginx
RUN apt-get install -y supervisor
RUN apt-get update && apt-get -q -y install lsof
RUN apt-get install net-tools
RUN apt-get install psmisc
RUN apt-get -y install curl
ADD supervisor.Nginx.conf /etc/supervisor.d/Nginx.conf
CMD /usr/bin/supervisord -n
RUN rm -Rf /etc/Nginx/conf.d/*
RUN rm /etc/Nginx/sites-enabled/default
RUN mkdir /etc/Nginx/logs/
RUN touch /etc/Nginx/logs/error.log
RUN mkdir /usr/share/Nginx/logs/
RUN touch /usr/share/Nginx/logs/error.log
ADD ./conf/Nginx.conf /etc/Nginx/sites-available/default
RUN ln -s /etc/Nginx/sites-available/default /etc/Nginx/sites-enabled/default
copy ./dist /usr/share/Nginx/html
CMD /usr/bin/supervisord -n
该docker文件将下面的Nginx配置文件复制到/ etc / Nginx / sites-available / default中,并为/ etc / Nginx / sites-enabled / default创建了一个符号链接到此文件.
server {
root /usr/share/Nginx/html;
index index.html index.htm;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/Nginx/html;
}
location ~* \.(jpg|jpeg|gif|png|css|js|ico|xml)${
access_log off;
log_not_found off;
expires 5d;
}
# deny access to . files,for security
#
location ~ /\. {
access_log off;
log_not_found off;
deny all;
}
}
然后我用
docker build -t dNginx
我启动了容器：
docker run --name d3 -d -p 80:80 dNginx
然后我找到了ip地址并尝试连接
curl http://172.17.0.2
哪个回来
curl: (7) Failed to connect to 172.17.0.2 port 80: Operation timed out
我在容器中打开一个bash shell并运行Nginx,它返回：
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] still could not bind()
如果我运行netstat –listen我得到：
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 *:80 *:* LISTEN
如果我运行netstat -ltnp | grep：80我得到：
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN -
我绝对不知道发生了什么.
如果我连接到Nginx图像,也会发生同样的情况.
最佳答案
我已经尝试了你的Dockerfile,它已经按预期工作了.我所做的唯一的改变就是删除任何涉及到上级和添加的内容
原文链接：https://www.f2er.com/nginx/434651.htmlCMD ["Nginx","-g","daemon off;"]
在Docker文件的末尾.
当容器启动时,其网络命名空间与主机和其他容器完全隔离,唯一的进程是由ENTRIPOINT或CMD指令及其子进程启动的,所以我认为您看到的Nginx进程在容器就是由supervisord运行的容器.
您确定172.17.0.2是docker容器的当前IP吗？
容器IP不稳定,它取决于主机上运行的容器数量和启动顺序.
您使用运行选项’-p 80:80’在主机上公开http端口,因此您应该能够使用curl 127.0.0.1在docker主机上访问它.
