Docker official registry (Docker Hub) URL
DockerDockerhubDocker Problem Overview
Docker Hub official website has been moved to https://registry.hub.docker.com from https://hub.docker.com/.
If I try to docker pull images from URL like: docker pull registry.hub.docker.com/busybox it shows:
registry.hub.docker.com/busybox: this image was pulled from a legacy registry.
Important: This registry version will not be supported in future versions of docker.
But if I use docker pull registry.hub.docker.com/busybox.
It cannot pull the image.
Same situation when using curl -k https://registry.hub.docker.com/v1/repositories/busybox/tags
Docker Solutions
Solution 1 - Docker
The registry path for official images (without a slash in the name) is library/<image>. Try this instead:
docker pull registry.hub.docker.com/library/busybox
Solution 2 - Docker
For those trying to create a Google Cloud instance using the "Deploy a container image to this VM instance." option then the correct url format would be
> docker.io/<dockerimagename>:version
The suggestion of registry.hub.docker.com/library/<dockerimagename> did not work for me.
I finally found the solution here (in my case, i was trying to run docker.io/tensorflow/serving:latest)

You're able to get the current registry-url using docker info:
...
Debug Mode (server): false
Registry: https://index.docker.io/v1/
Labels:
...
That's also the url you may use to run your self hosted-registry:
docker run -d -p 5000:5000 --name registry -e REGISTRY_PROXY_REMOTEURL=https://index.docker.io registry:2
*ix friends, grep & use it right away:
$ echo $(docker info | grep -oP "(?<=Registry: ).*")
https://index.docker.io/v1/
UNTESTED Windows friends, findstr & use it right away:
$ docker info | findstr /R /C:"(?<=Registry: ).*"
https://index.docker.io/v1/
> I drafted a Windows version of the command – unfortunately i'm not able to test it. Please leave a comment if it doesn't work or you have any other feedback. Thanks.
Solution 4 - Docker
I came across this post in search for the dockerhub repo URL when creating a dockerhub kubernetes secret.. figured id share the URL is used with success, hope that's ok.
Live Current: https://index.docker.io/v2/
Dead Orginal: https://index.docker.io/v1/

It's just docker pull busybox, are you using an up to date version of the docker client. I think they stopped supporting clients lower than 1.5.
Incidentally that curl works for me:
$ curl -k https://registry.hub.docker.com/v1/repositories/busybox/tags
[{"layer": "fc0db02f", "name": "latest"}, {"layer": "fc0db02f", "name": "1"}, {"layer": "a6dbc8d6", "name": "1-ubuntu"}, {"layer": "a6dbc8d6", "name": "1.21-ubuntu"}, {"layer": "a6dbc8d6", "name": "1.21.0-ubuntu"}, {"layer": "d7057cb0", "name": "1.23"}, {"layer": "d7057cb0", "name": "1.23.2"}, {"layer": "fc0db02f", "name": "1.24"}, {"layer": "3d5bcd78", "name": "1.24.0"}, {"layer": "fc0db02f", "name": "1.24.1"}, {"layer": "1c677c87", "name": "buildroot-2013.08.1"}, {"layer": "0f864637", "name": "buildroot-2014.02"}, {"layer": "a6dbc8d6", "name": "ubuntu"}, {"layer": "ff8f955d", "name": "ubuntu-12.04"}, {"layer": "633fcd11", "name": "ubuntu-14.04"}]
Interesting enough if you sniff the headers you get a HTTP 405 (Method not allowed). I think this might be to do with the fact that Docker have deprecated their Registry API.
Solution 6 - Docker
For those wanting to explicitly declare they are pulling from dockerhub when using fabric8 maven plugin, add a new property: <docker.pull.registry>registry.hub.docker.com/library</docker.pull.registry>
I arrived on this page trying to solve problem of pulling from my AWS ECR registry when building Docker images using fabric8.
