I'm trying to Dockerize my FastAPI app along with a MySQL database, but I'm hitting some snags. I have a Dockerfile set up to build the FastAPI image and a docker-compose.yml to run both the FastAPI and MySQL containers (with a pre-made MySQL image). I'm working on Windows 11 using WSL, and my Docker version is 28.5.1.
**Here's the main error I'm dealing with:**
When I run `docker-compose up --build`, I see errors indicating status failures and connection issues. I also tried building the FastAPI image manually with `docker build -t fastapi .` but received a 500 Internal Server Error for the API route.
**I've tried the following solutions:**
1. Restarted Docker-Desktop.
2. Reinstalled Docker-Desktop.
3. Attempted to build the image manually.
**What I suspect could be the issue:**
1. Docker-Desktop keeps stopping unexpectedly.
2. Potential internal server errors related to the Docker Engine connection.
Any assistance would be appreciated as I'm fairly new to both Reddit and Docker!

Try executing some CURL commands directly in WSL2 to see if there's an internet connection problem. My work laptop had a similar issue due to restrictions, and it wouldn't let me run essential updates. If that’s blocked too, you may need to switch to a VM or consider dual-booting.
It sounds like you might actually be having issues with Docker Desktop running on WSL2 rather than with FastAPI itself. If you haven't tried it yet, consider running Docker on a native Linux OS or even setting up a VM for it. That might simplify things for you!
Thanks! I'll look into migrating to Ubuntu and see if that helps.
This definitely seems more like a Docker Desktop issue than FastAPI. Have you checked your Docker Engine settings and whether WSL is configured correctly? That might give you more insight into the problem.
Yeah, I just used FastAPI as a reference point. I think the problem is more related to Docker Engine or WSL.
It could also help to check the Docker logs for any additional error messages or hints. Sometimes they provide insights into the server connection issues you're facing. Good luck!
Have you thought about removing Docker Desktop completely and reinstalling Docker directly in WSL? A fresh install might clear up these random errors you're facing.
I don’t have a work laptop, but I'll give the CURL command a try in WSL2.
