Docker official registry (Docker Hub) URL

Question

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:

Answer 1

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 above 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)

Answer 2

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.

Answer 3

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/

Answer 4

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

Answer 5

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

---

Grep & use it right away:

$ echo $(docker info | grep -oP "(?<=Registry: ).*")
https://index.docker.io/v1/

Answer 6

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.
