Connect to host mongodb from docker container

You can use: 172.17.0.1 as it is the default host ip that the containers can see. But you need to configure Mongo to listen to 0.0.0.0.

From docker 18.03 onwards the recommendation is to connect to the special DNS name host.docker.internal

For previous versions you can use DNS names docker.for.mac.localhost or docker.for.windows.localhost.

change the bindIp from 127.0.0.1 to 0.0.0.0 in /etc/mongod.conf. Then it will work
