一、准备工作

1、下载基础镜像

docker pull centos:7.8.2003

2、创建存放nginx的目录和Dockerfile文件

mkdir /home/nginx

cd /opt/nginx

touch Dockerfile

3、下载nginx源码包到nginx目录下

wget http://nginx.org/download/nginx-1.18.0.tar.gz

二、编写Dockerfile

1、配置文件，注意添加daemon off;不是以守护进程启动，否则进程进行完成会自动关闭，容器无法再访问

vim Dockerfile

FROM centos:7.8.2003

ENV PATH /usr/local/nginx/sbin:$PATH

EXPOSE 80
EXPOSE 443

ENTRYPOINT ["nginx"]

CMD ["-g","daemon off;"]

2执行docker build进行构建，注意命令后的.需要把文件夹下载的nginx打包进去

docker build -t centos7.8_nginx1.18:v1 .

Successfully built 3ae0d07c99ec
Successfully tagged centos7.8_nginx1.18:v1

3构建成功提示，并查看

[root@nginx]# docker image list
REPOSITORY TAG IMAGE ID CREATED SIZE
centos7.8_nginx1.18 v1 3ae0d07c99ec About a minute ago 462MB

三、启动新镜像

1、-d后台运行，-p指定端口，-v映射路径

mkdir -p /home/nginx/www /home/nginx/conf/

1
docker run -d -p 8168:80 --name nginx-rancher-168 -v /home/nginx/www:/usr/share/nginx/html -v /home/nginx/conf/nginx.conf:/usr/local/nginx/conf/nginx.conf  centos7.8_nginx1.18:v1

2、查看容器

# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                NAMES
7487ad7d9bc1        centos_nginx:v1     "nginx -g 'daemon of…"   About a minute ago   Up About a minute   0.0.0.0:80->80/tcp   nginx-v1

3、浏览器访问地址即可

四、重新编译nginx

1、进入容器内部

docker exec -it nginx-v1 /bin/bash

2、重新编译

在./configure 后添加参数，增加需要的模块
