The problem seems to be with the IP address, which is constanly changing.

The way I manage to workaroud this problem is by:

1. Enter the mariadb docker container: docker exec -ti <CONTAINER_ID> bash
2. Enter mysql: mysql -u root -p (default pass is 123)
3. Using wildcards for mysql.user’s and mysql.db’s Hosts: 3.1. UPDATE mysql.user SET host = '172.30.0.%' WHERE host = '172.30.0.2'; 3.2. UPDATE mysql.db SET host = '172.30.0.%' WHERE host = '172.30.0.2'; 3.3. FLUSH PRIVILEGES;

Then it works.

This is just a workaround. There should be a better solution. Thanks

Now there is --no-mariadb-socket option available in bench new-site command. It sets the credential suitable for docker at the time of site creation.

pull the latest bench image

docker pull frappe/bench:latest
