The guide DHCP with docker-compose and bridge networking is very well written and I think I followed all the steps correctly. But the alpine container seems to be unable to get an internet connection. I tried to add a custom mirror to make sure it's not a mirror related issue but it still won't work.

I tried this with my own compose file but tried it later with yours too. I also compared mine to yours with vimdiff to make sure that I do not have any syntax errors in my file.
The internet connection on the Pi itself works flawlessly.
My compose file looks like this and I'm building it with docker-compose up. I hope this is correct.:
