How to use docker container attach command to interact with running containers

# Introduction

In this lab, you will learn how to use the `docker container attach` command to interact with running containers. You will start containers in detached mode, attach to them to observe their output, and detach using the default key sequence.

You will also explore attaching to containers with TTY enabled and learn how to override the default detach key sequence for greater flexibility when interacting with your Docker containers.
