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
- docker run -d -p 5000:5000 registry
- 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
