看一下对三个词的英文解释:
An index manages user accounts, permissions, search, tagging, and all that nice stuff that’s in the public web interface.
A registry stores and serves up the actual image assets, and it delegates authentication to the index. Docker registry is a service that is storing your docker images.
Docker repository is a collection of different docker images with same name, that have different tags.
Index
是管理docker
的服务(包含用户账户,操作权限,等等)。Registry
是存储docker image
的服务。Repository
则是包含同名不同tag
的docker image
的集合。
