Workaround for this should be:
docker compose -f docker-compose.simple-install.yml down
now, when the MySQL container is built, on the second attempt eramba container should be able to connect to it. We need to compose again:
docker compose -f docker-compose.simple-install.yml up -d
I’m also creating an issue, so we handle this error properly during the first run.
