How to Pass Username and Password in Telnet Command to Pull Docker Image

If you're looking to pull a Docker image using the telnet command and need to pass a username and password, it's important to follow the right steps to ensure security and seamless access. The telnet protocol doesn't natively support passing credentials like a username and password for authentication. However, you can utilize other methods to achieve the same outcome.

Option 1: Using Docker Login

One way to handle authentication when pulling a Docker image is to use the docker login command. This command allows you to authenticate with a Docker registry using your Docker Hub username and password.

docker login --username YOUR_USERNAME --password YOUR_PASSWORD

Option 2: Using Docker Config File

Another approach is to create a config.json file that stores your Docker registry credentials. This file can then be used by Docker when pulling images.

{"auths":{"your.docker.registry":{"username":"YOUR_USERNAME","password":"YOUR_PASSWORD","email":"YOUR_EMAIL"}}

By following these methods, you can securely pass your username and password when pulling Docker images without compromising security.
