94db415a384f
[root@izbp1e0h5tks006vnlaro4z bin]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

Specify the parameters of the container nginx

docker run --name nginx-001 -d -p 8080:80 -v /home/docker/nginx/html:/usr/share/nginx/html nginx

The -p parameter is to map the host's port 8080 to the container's port 80. Note that -v is a data volume, and the directory /home/docker/nginx/html can be shared between the host and the container. In the container, it is /usr/share /nginx/html. In fact, this is our code directory. The debugging code is realized by the shared directory, which is very convenient! !

Modify the configuration file in the container

#进入容器
$docker exec -it nginx-001 bash
#安装工具
apt-get update
apt-get install vim
#查看和修改nginx的配置信息
vim /etc/nginx/conf.d/default.conf
