通过dockerfile制作nginx镜像

首先创建nginx目录，然后进入目录编辑Dockerfile

[root@Raygussie ~]# mkdir nginx
[root@Raygussie ~]# ls
anaconda-ks.cfg  nginx  nginx-1.14.2.tar.gz  nginx-1.19.7  nginx-1.19.7.tar.gz
[root@Raygussie ~]# cd nginx/
[root@Raygussie nginx]# ls
[root@Raygussie nginx]# vi Dockerfile

//第一行FROM指令后输入基础镜像
FROM centos

//指定镜像用户的信息
LABEL MAINTAINER='mufeng 123@qq.com'

//安装编译nginx的依赖的安装包
RUN yum -y install gcc gcc-c++ make libtool zlib-devel openssl openssl-devel pcre pcre-devel vim wget unzip zip 

//创建nginx账户，设置不允许登录
RUN useradd -r -M -s /sbin/nologin nginx

//使用ADD指令解压nginx软件包
ADD /nginx-1.19.7.tar.gz /usr/local 

//定义nginx工作路径
WORKDIR /usr/local/nginx-1.19.7

//编译安装nginx
RUN /bin/bash ./configure --prefix=/usr/local/nginx --with-http_ssl_module

//通过make编译安装nginx
RUN make&&make install

//定义向外暴露的端口号
EXPOSE 80

//启动容器执行指令
CMD ["/usr/local/nginx/sbin/nginx", "-g","daemon off;"]

通过docker build命令来创建镜像

[root@Raygussie ~]# docker build -t mf/web:v0.4 nginx/
Sending build context to Docker daemon  1.059MB

 ---> 562f44bd9793

Successfully tagged mf/web:v0.4

运行容器，端口为80端口

[root@Raygussie ~]# docker run -it -p 80:80 --name mf3 mf/web:v0.4

在另一个终端查看端口

[root@Raygussie ~]# ss -antl
State    Recv-Q    Send-Q         Local Address:Port         Peer Address:Port    
LISTEN   0         128                  0.0.0.0:22                0.0.0.0:*       
LISTEN   0         128                  0.0.0.0:80                0.0.0.0:*       
LISTEN   0         128                     [::]:22                   [::]:*      

最后打开网站，输入主机的ip，界面里出现了Welcome to nginx！
