Login to Docker Hub by command line

Question

I have read some Docker tutorials and I see this command line:

docker login -u LOGIN -p PASSWORD

But the registry server URL is never set. How does the docker command know the registry URL? What is the URL for Docker Hub Registry? I have tried this:

docker login -u LOGIN -p PASSWORD cloud.docker.com

but it does not work.

Answer 1

If you want to login to the default Docker Hub repository, simply use:

docker login

or more specifically:

docker login registry-1.docker.io

Answer 2

You may need to use a specific registry version, for me this worked.

docker login registry-1.docker.io/v1

Answer 3

You can also login using a Docker Hub Access Token: https://docs.docker.com/docker-hub/access-tokens.

To do that:

1. Access your Docker Hub account.
2. Click on your avatar (on the page top right side).
3. Click on Account and Settings.
4. Click on Security (on the page left side in the middle).
5. And then click on New Access Token button.

6. Give a token description, define the token permissions and click on Generate.
7. Copy and save your token.

Then log in with your new token. Type docker login -u <your-username> on your terminal and paste your Access Token when requested by the password.

docker login -u <your-username>
