How to authenticate with Docker Hub?

To authenticate with Docker Hub, follow these steps:

1. Open your terminal.

2. Run the Docker login command:

   docker login

3. Enter your Docker Hub credentials:

   • You will be prompted to enter your Docker Hub username.
   • After entering your username, you will be prompted to enter your password.

4. Successful Authentication: If your credentials are correct, you will see a message indicating that the login succeeded.

Alternatively, if you want to specify the registry server explicitly, you can use:

docker login docker.io

This process will store your credentials in an unencrypted format in your Docker configuration file, typically located at ~/.docker/config.json. For enhanced security, consider configuring a credential helper.
