Googling the error found this: eventlet/eventlet#370
I noticed the inclusion of eventlet at the requirements file. After removing it I could successfully start the container, but I ignore what issues it might generate on the app performance

MySQL is up

That doesn't seem to be our container, that supports PostgreSQL only and does not use eventlets, so please use https://hub.docker.com/r/weblate/weblate/ instead. Eventlet is not used by our container because it's broken on Python 3.7, see eventlet/eventlet#526 (and #340).

I am using your container https://github.com/WeblateOrg/docker/tree/3.8-4 customized for MySQL support, I am doing no more changes. May I then ignore the eventlet dependency at https://github.com/WeblateOrg/docker/blob/3.8-4/requirements.txt ?

Ah good point, it was mistakenly not removed there while removing it's usage.

And MySQL support will be dropped in future Weblate versions, see WeblateOrg/weblate#2825
