Hey everyone! I've been running Docker for Windows to manage a simple reverse proxy with Nginx, and it has been functioning well for about a month at a time. However, it suddenly stops working, which forces me to manually restart the Docker engine to get it back up. This feels really inconvenient and makes me suspect there's a deeper issue with the software.
The error message I get is: "docker: request returned Internal Server Error for API route and version" followed by a URL that doesn't help much. This has been happening monthly, and I'm really at a loss since it runs perfectly until it doesn't!
I've tried setting up a daily task to restart the containers automatically, but that hasn't worked since Docker commands fail when the crash happens. Browsing the internet, I've mostly found people suggesting a manual restart, but I'm looking for a more permanent fix or workaround. I've only adjusted a few basic settings and I'm using the recommended WSL2 backend for performance.
Does anyone know why this might be happening or how to work around it? My PC has limited memory and cores due to some other tasks I'm running, but I can't imagine that's affecting a simple proxy server setup. Here's a snippet of my WSL config: [wsl2] memory=1GB processors=2. Any insights would be greatly appreciated!

I've been through the same frustrations with Docker on Windows. It's generally better to run dedicated services on Linux as the underlying system. Windows can run some apps fine, but Docker isn't one of them long-term. The complexities you face from the extra layers with WSL are usually the culprit behind the crashes and instability. Trust me, switching to a Linux server or VM will save you a lot of headache in the long run!
It’s legit the best decision you can make! Start with a simple Ubuntu install and you’ll get the hang of things!
Running Docker on Windows, especially with WSL2, can often lead to instability due to several reasons. Windows is not the best choice for hosting services meant to be reliable all the time. Docker Desktop uses WSL2 to run a Linux VM which is great for development but not so much for production. If you're serious about reliability with Nginx, I’d suggest moving to a dedicated Linux OS or using a proper VM like VMware or VirtualBox. This way, Docker runs natively on Linux, reducing the chances of encountering the issues you’re facing.
Would it be smarter to set up a dedicated Ubuntu VM for running Docker instead of WSL?
Thanks for the detailed reasoning! I’m definitely considering switching to Linux for my Nginx setup; it sounds like a more stable option.
Honestly, Docker on Windows can be a pain. WSL2 is meant for lightweight tasks and isn't designed to handle long-running services well. You could try switching to Hyper-V for better performance and stability instead. I've found that it helps with issues that arise when using WSL. Just remember, using Windows for something like this is often a temporary solution until you're ready to learn Linux for running your containers more smoothly.
Doesn't Hyper-V still use some features from WSL? Would that make a difference?
Switching to Hyper-V sounds like it could be worth it! I hadn’t thought of that.
I'm pretty much a newbie to Linux; any tips on where to start migrating?
