V4 beta unable to connect to db via localhost?

Just installed the v4 beta, and can’t make any localhost connection to the db, not via command line, not forwarded via ssh, nothing. When I look at the file system in the wp-config.php file, it appears the host is defined as “db”, but that also fails to work. I assume this has something to do with it running inside docker? Can you enlighten me as to how I can make a direct connection to the db, other than using your built in pma instance (which I can’t find config files for in the filesystem)?


Same problem here, on Debian 8. On Ubuntu 16.04.4 LTS I don’t have that problem.

Thanks that is useful info. I was on Ubuntu 18.04, so perhaps that is the issue. I will try 16.04.
