1构建Nginx镜像
1建立工作目录
[root@localhost ]# mkdir 1nginx
[root@localhost 1nginx]# cd 1nginx/
[root@localhost 1nginx]# ls
Dockerfile nginx-1.14.2.tar.gz run.sh
2，创建并编写Dockfile文件
[root@localhost 1nginx]# vim Dockerfile
#创建者的基本信息
MAINTAINER adc@163.com
#解决依赖关系
RUN yum install -y make gcc openssl-devel pcre-devel zlib-devel
#添加nginx用户
RUN groupadd -r nginx && useradd -r -g nginx -s /bin/false -M nginx
#添加nginx安装包，并默认解压
ADD nginx-1.14.2.tar.gz /usr/local/src/
#添加启动nginx服务脚本
ADD run.sh /run.sh
#定义工作目录
WORKDIR /usr/local/src/nginx-1.14.2/
#执行命令进行安装
RUN ./configure \
–prefix=/usr/local/nginx \
–sbin-path=/usr/sbin/nginx \
–conf-path=/etc/nginx/nginx.conf \
–error-log-path=/var/log/nginx/error.log \
–http-log-path=/var/log/nginx/access.log \
–pid-path=/var/run/nginx/nginx.pid \
–lock-path=/var/lock/nginx.lock \
–user=nginx \
–group=nginx \
–with-http_ssl_module \
–with-http_flv_module && make && make install
#定义输出命令
CMD [“/run.sh”]
#定义输出端口
EXPOSE 80
3.编写执行脚本内容
[root@localhost 1nginx]# vim run.sh
#!/bin/bash
sed -i ‘/daemon off/d’ /etc/nginx/nginx.conf
#设置nginx非daemon守护进程
echo “daemon off;” >> /etc/nginx/nginx.conf
#杀掉nginx服务
killall nginx
#启动nginx服务
/usr/sbin/nginx -c /etc/nginx/nginx.conf
- 生成镜像
[root@localhost 1nginx]# docker build -t nginx.web .
[root@localhost 1nginx]# docker images
- 启动容器进行测试
[root@localhost 1nginx]# docker run -d -p 81:80 nginx.web
[root@localhost 1nginx]# docker ps
[root@localhost 1nginx]# curl 192.168.30.24:81
