Create a configuration file for Docker

README.MD

To create a valid .docker/config.json file you first need to base64 encode your username and password:

echo <username>:<password> | base64

The output will look like this:

~ echo hallo:welt | base64
aGFsbG86d2VsdAo=

Then you can create your config.json file:

echo '{
  "auths": {
    "https://index.docker.io/v1/": {
      "auth": "XXX"
    }
  }
}' > config.json

Then open the file and exchange XXX with the encoded username/password you created earlier.

If you need to create a config for another registry, exchange https://index.docker.io/v1/ with the url of the custom registry.

config.json

{
  "auths": {
    "https://index.docker.io/v1/": {
      "auth": "XXX"
    }
  }
}
