docker: Log into a registry with a specific username (user will be prompted for a password).

docker

$ docker login --username ${username}

try on your machine

The docker login command is used to authenticate a user to a Docker registry. It allows you to login to either Docker Hub (default registry) or to a private registry. In this specific command: docker login --username ${username} - docker login is the command itself.

--username is an option flag used to specify the username for logging in.
${username} is a placeholder or variable that should be replaced with the actual username you want to use for logging in. For example, if you want to login to Docker Hub with the username "john123", you would replace ${username} with john123 in the command: ``` docker login --username john123
