How to Backup DevContainer State to Avoid Losing Changes on Rebuild

[Ekanshh]

Hello!

I'm new to using VSCode DevContainers, and I’ve set up a development environment that I’d like to save. I've customized a lot of settings and installed various tools inside the container, and I'm worried that if I accidentally rebuild it, I might lose all those changes.

Is there a way to "backup" the current container image so that I can use it again later with all my current settings and installations intact?

Any step-by-step guidance would be greatly appreciated. Thanks in advance for your help! 😊
