How to get a list of images on docker registry v2

For the latest (as of 2015-07-31) version of Registry V2, you can get this image from DockerHub:

docker pull distribution/registry:master

List all repositories (effectively images):

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

List all tags for a repository:

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

If the registry needs authentication you have to specify username and password in the curl command

curl -X GET -u <user>:<pass> https://myregistry:5000/v2/_catalog
curl -X GET -u <user>:<pass> https://myregistry:5000/v2/ubuntu/tags/list

you can search on

http://<ip/hostname>:<port>/v2/_catalog
