Docker4drupal: Failed to connect to your database server

[KN-Bill]

Docker-compose went well but when I get to the Set up database section of the install using
Database name: drupal
Database username: drupal
Database password: drupal

I get the following error:
Failed to connect to your database server. The server reports the following message: SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2 "No such file or directory").

Docker newbie here, thanks

Hi, you should use mariadb (service name in docker-compose.yaml) as mariadb hostname not localhost.

Thanks, PavelPrischepa, sorry about my slow response. Life threw me a hiccup. >:-|

I did make that change but now seems to be getting hung up while getting ready for start up. It just keeps repeating the last line from the following terminal reprint:

It does that until I hit CTR C

Thanks again for your help!

Try to remove volumes from mariadb service definition then docker-compose down and docker-compose up.
