CentOS7 Docker Nginx部署及运行详解

网上找了一些资料部署，出现不一样的问题，现在总结一下自己的部署流程。

1、资源准备

Dockerfile文件

RUN yum -y update; yum clean all
RUN yum -y install epel-release tar ; yum clean all
RUN yum -y install nginx ; yum clean all
ADD nginx.conf /opt/deploy/nginx/nginx.conf
RUN echo "daemon off;" >> /opt/deploy/nginx/nginx.conf
#RUN curl https://git.centos.org/sources/httpd/c7/acf5cccf4afaecf3afeb18c50ae59fd5c6504910 \
#  | tar -xz -C /usr/local/nginx/html \
#  --strip-components=1
#RUN sed -i -e 's/Apache/nginx/g' -e '/apache_pb.gif/d' \
#  /usr/local/nginx/html/index.html 

EXPOSE 80 

#CMD [ "/usr/local/nginx/sbin" ] 

注意：路径需要在系统上面存在以及对应

nginx.conf文件

2、执行构建镜像命令

代码如下:

[root@localhost nginx]# sudo docker build --rm --tag os7/nginx:centos7 .

执行结果截图：

3、查看镜像是否安装构建成功 Docker images

4、创建容器 docker run -i -t -d -p 192.168.32.129:81:80 os7/nginx /bin/bash

注意：192.168.32.129这个IP的话，则需要在/etc/hosts中添加

192.168.32.129     localhost

5、查看容器是否创建成功并启动 docker ps

6、测试是否成功访问 curl http://192.168.32.129:81

会出现这个拒绝连接，那怎么办呢？有办法解决的，我们先进入该容器里面

7、进入容器 docker exec -i -t small_hodgkin /bin/sh

8、接着在容器里面执行（直接输入即可）

nginx

9、在容器外面执行 curl http://192.168.32.129:81

成功了。

10、再到虚拟机外面通过浏览器访问

到此为止就成功了。
