How To Restart Docker

How To Articles

Hey there, fellow tech enthusiasts! Today, I want to delve into a topic that’s essential for anyone working with Docker – restarting Docker. As a developer who uses Docker on a daily basis, I’ve had my fair share of experiences with restarting Docker, and I’m here to share my insights with you.

Understanding the Need to Restart Docker

Before we dive into the nitty-gritty of how to restart Docker, let’s briefly touch on why we might need to do so. Docker, as powerful and efficient as it is, can sometimes encounter issues or run into conflicts with other software. This can lead to services not running as expected, and that’s when a restart becomes necessary.

Restarting Docker on Linux

For those of us using Linux, restarting Docker is a relatively straightforward process. First, open up your terminal and enter the following command:

sudo systemctl restart docker

This command tells the system to restart the Docker service, bringing it back to its initial state and resolving any ongoing issues. If you’re prompted for a password, simply enter your system password, and you’re good to go!

Restarting Docker on Windows

Now, for my fellow Windows users, restarting Docker is just as simple. Start by opening a Windows command prompt or PowerShell window, and input the following command:

Restart-Service Docker

Executing this command will initiate the restart process for the Docker service on your Windows machine. After a few moments, Docker should be up and running smoothly again.

Restarting Docker on macOS

For those of us working on macOS, restarting Docker follows a slightly different process. To restart Docker on macOS, open up a terminal window and execute the following command:

killall Docker && open -a Docker

This command effectively kills the Docker process and then restarts it, ensuring a clean and fresh start for your Docker environment on macOS.


And there you have it – a detailed guide on how to restart Docker on different operating systems. Whether you’re troubleshooting issues or simply ensuring that Docker runs smoothly, knowing how to restart Docker is a valuable skill for any developer. I hope this guide helps you in your Docker journey, and remember, when in doubt, a quick restart often works wonders!
