docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com


Start interactive shell

Benny@Taurus MINGW64 /l/Program Files/Docker Toolbox
$

查看已有映像

docker image ls

拉取映像文件

docker pull registry.docker-cn.com/library/nginx:latest
docker pull registry.docker-cn.com/library/php:fpm
docker image pull library/hello-world

创建并启用容器

cd /c/Users
mkdir Docker
cd Docker
wget https://github.com/wuding/webot/archive/master.zip
unzip master.zip
cd webot
docker-compose up -d

浏览器访问 http://192.168.99.100

重启虚拟电脑

docker-machine restart

打开 VirtualBox

虚拟系统界面

  1. 关闭虚拟电脑 default
  2. 配置系统内存大小、处理器数量和运行峰值

启动 Kitematic (Alpha)

  1. 启动容器
  2. 点击 EXEC 命令窗口
  3. 找到要映射的目录和文件
  4. 复制到本地磁盘
docker container cp webot_nginx_1:/etc/nginx/nginx.conf /c/Users/Docker/webot/etc/nginx/nginx.conf

容器上的目录和文件可以不存在，只要映射的本地有就可以了

靠谱的方式是先不映射目录，按默认配置运行正常了再改

编写 .dockerignore 和 Dockerfile 文件

发布映像

docker login
docker image build -t wuding/blog:latest .
dcoker run -d -p 8000:80 wuding/blog:latest
docker image push wuding/blog:latest
