How to get a list of images on docker registry v2

Question

Hey there, I've been using the docker registry v1 for some time now, but now I want to migrate to version V2. 

Now there is one issue before I can do that, I want to know how I can list all of the images on the registry in V2, with V1 we can use a GET request to http://myregistry:5000/v1/search? with this result:

{
  "num_results": 2,
  "query": "",
  "results": [
    {
      "description": "",
      "name": "deis/router"
    },
    {
      "description": "",
      "name": "deis/database"
    }
  ]
}

So far I haven't found anything similar to this to get the list of all the images on the registry in V2. Can someone help me out?

Answer 1

To list all of the images ( repositories ) you can use the below command:

curl -X GET https://myregistry:5000/v2/_catalog > {"repositories":["redis","ubuntu"]}

To get all repository's tags use the below command:

curl -X GET https://myregistry:5000/v2/ubuntu/tags/list
> {"name":"ubuntu","tags":["14.04"]}

Hope that helped :)
