May 23, 2018 Here a locally running database on a mac device is used so, dbHost=docker.for.mac.localhost. Configure the properties as required. To build the Jasper server image use the following command. Now, connections to localhost:8000 are sent to port 80 in the container. The syntax for -p is HOSTPORT:CLIENTPORT. HTTP/HTTPS Proxy Support. Known limitations, use cases, and workarounds. Following is a summary of current limitations on the Docker Desktop for Mac networking stack, along with some ideas for workarounds.

It should be straitforward, but it’s not, because docker uses a virtual machine on Macs.
Yes, this is it. As you can probably tell from this image — I’m running a netcat server listening to the 23456 port, and I can send a message from a (busybox) container to it.
So if you have any service running on your localhost, this is how you can access it.

It is almost the first thing in the Netwoking chapter of the Docker for Mac documentation:
I WANT TO CONNECT FROM A CONTAINER TO A SERVICE ON THE HOST
The host has a changing IP address (or none if you have no network access). From 18.03 onwards our recommendation is to connect to the special DNS name
host.docker.internal , which resolves to the internal IP address used by the host. This is for development purpose and will not work in a production environment outside of Docker for Mac.

The gateway is also reachable as
gateway.docker.internal .
Also, docker.for.mac.host.internal points to the same host.
