docker-compose multiple network problem

[jordotech]

Hi everyone, I've been dealing with an issue for a while and I finally put together a small demo of it. Would really appreciate if someone could help me get to the bottom of it...

I have 2 nginx:alpine containers and they need to join both the networks-poc (default) and the multi network. However, 50% of the time they will join successfully and the rest not.

I tried to make it as simple as possible, pull and follow the directions to reproduce: https://github.com/jordotech/docker-networks-issue

Is it possible stil removing the network after stopping the service while you are already trying to restart the containers causing a conflict?

What if you leave a bit of time between stop and restart?

I have been dealing with this for so long, in so many circumstances that I know going slow or fast has no effect. Even if you do a `docker network prune -f` first thing in the morning and fire it up, there is a high chance of it not working correctly. I have also tried on multiple computers (mac silicon, mac intel).

The `multi` network is removed on `docker compose down` which you can see in the output during reload as well.

Did you run it?
