How to Conveniently SSH Into a Docker Container From a Windows Host

In the world of containerization, Docker has become a pivotal tool for developers. However, there are times when you need to access the shell of a running container for troubleshooting or management purposes. If you're running a Docker container on a Windows host machine, this guide will show you how to securely connect to it using SSH.

Prerequisites

Before we dive in, ensure that you have the following:

Docker Installed: Make sure Docker is installed and running on your Windows host machine.

SSH Client: An SSH client should be installed on your Windows machine. Windows 10 and later versions come with a built-in OpenSSH client.

Step-by-Step Guide

Run a Docker Container
First, let's start a Docker container. We'll use an Ubuntu image for this demonstration:

This command pulls the latest Ubuntu image and runs it in detached mode with the name my_ubuntu_container.

Install SSH Server Inside the Container
Next, access the shell of the running container:

You'll be prompted to enter a new password.

Expose Port 22
To access the SSH server from your host machine, you need to expose port 22. This can be done during container creation or by modifying the existing container.

Here's how to run a new container with port 22 exposed:

Enter the root password you set earlier to gain shell access to the Docker container.

Conclusion
With these steps, you can successfully SSH into a Docker container from your Windows host machine. This method provides a practical way to manage and troubleshoot containers efficiently. Whether you're a seasoned developer or a newcomer to Docker, mastering these commands can significantly enhance your productivity.

Happy coding!
