How to pull from private docker repository on docker hub?

Question

I create a automated build repository on dockerhub (via github) and try to pull the image which is automatically built onto cloud server.

using things like

docker pull com.company/project:tag

but it gives me

Error: image com.company/project:tag not found

it usually works for public repository, do I have to do something else for private repository ?

Sounds like you need to setup a private Docker registry to host your built images. In other words do a "docker push" before you can do a "docker pull" — Mark O'Connor, Aug 04 '15 at 01:25
solved by meself, "docker login" is needed for authentication — Hello lad, Aug 04 '15 at 10:00

You just need to use the command docker login with your sign parameters from docker hub.

Another way to do this is to create a docker config.json file. The file should be placed in ~/.docker/config.json and the Docker Hub authorization token can be specified in the file.

{
    "auths": {
        "https://index.docker.io/v1/": {
            "auth": "my-docker-hub-generated-auth-token"
        }
    }
}

This is a useful strategy if you are working with servers that need the ability to run scripts that pull images from Docker Hub.

Resources and further infomration:

The current implementation is `base64("username:token")`. Using `docker login registry.url.here -uusername -p` should generate the correct data. — ssi-anik, Jan 06 '22 at 13:04
