docker access host from containner
host.docker.internal
+300
Edit:
If you are using Docker-for-mac or Docker-for-Windows 18.03+, just connect to your
mysql service using the host host.docker.internal
(instead of the 127.0.0.1 in your connection string).
If you are using Docker-for-Linux 20.10.0+, you can also
use the host host.docker.internal if you started your Docker container with
the --add-host host.docker.internal:host-gateway option.
Otherwise, read below
