docker 其他的基本命令

运行 nginx

  • 运行测试 nginx_t 容器
1
docker run --name nginx_t -d -p 80:80 nginx:latest
  • 进入容器，查看 nginx.conf 文件位置

3
docker exec -it nginx_t /bin/bash
nginx -t
#/etc/nginx/nginx.conf

mkdir -p nginx
mkdir -p nginx/conf
mkdir -p nginx/html

 #拷贝文件
docker cp nginx_t:/etc/nginx/nginx.conf /root/nginx/conf/
 #拷贝文件夹
docker cp nginx_t:/etc/nginx/conf.d/ /root/nginx/conf/
 #拷贝文件夹
docker cp nginx_t:/usr/share/nginx/html/ /root/nginx/html/

docker stop nginx_t
#删除
docker rm nginx_t
  • 修改 nginx.conf 文件，启动正式容器

# --link 连接其他容器
