docker仓库

docker仓库是存放镜像的地方，分为共有仓库和私有仓库。

搭建docker本地私有仓库

• 使用registry镜像创建私有仓库
  
  • docker run -d -p 5000:5000 registry
    • 支持的参数：-v：指定registry镜像存放的本地位置，默认是存放到容器、temp/registry目录下
    • docker run -d -p 5000:5000 -v /usr/local/docker/images/registry  registry
  • 以上命令，自动下载并创建registry容器，并创建私有仓库，监听端口为5000
• 上传镜像到私有仓库
  • 将镜像命名为： ip:端口号/镜像名称。 例如：docker tag redis 127.0.0.1:5000/myredis
  • docker push 127.0.0.1:5000/myredis
• 查看私有仓库的镜像
  • 查看私有仓库的镜像： curl -XGET http://127.0.0.1:5000/v2/_catalog
  • 获取某个镜像的标签列表： curl -XGET http://127.0.0.1:5000/v2/myredis/tags/list
• 从私有仓库下载镜像
  • docker pull ip:端口号/镜像名称
