MAC DOCKER IP FOR MAC
MAC DOCKER IP UPDATE

Note: I don't run it as sudo here, but remember that sudo won't work with export! To become an env var, we need export it first, and then run docker-compose: $ :~$ export HOST_IP=$HOST_IP & docker-compose up -d env file, and HOST_IP is only a shell variable. This mechanism also available docker-compose.yml files as the extra_hosts key, like so:ДЄnd since we took advantage of variable substitution in CLI example, I'll show how we can do the same here: version: '2' This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac. From 18.03 onwards our recommendation is to connect to the special DNS name, which resolves to the internal IP address used by the host. The host has a changing IP address (or none if you have no network access). ping statistics -ДЎ packets transmitted, 1 packets received, 0% packet loss ping statistics -Дў packets transmitted, 2 packets received, 0% packet loss Additionally, you can also now also use to access the host's gateway.

Update April 2019: The DNS name is now called in the docs, though works just as well for now in Docker 18.09.3. Instead, you can actually simply go into the container and use a special macOS-only DNS name ( ) that comes out of the box (version 17.06+):

MAC DOCKER IP FOR MAC

This supposedly also works on Windows, but as I don't have a Windows dev machine, I can't test it.Дocker for Mac does not have the docker0 interface 1 that's used in the above example. Now, within the container, we can inspect /etc/hosts, we see an extra line has been added: :~$ docker run -add-host outside:$HOST_IP -name busybox -it busybox /bin/sh Then we execute docker run with -add-host, using the variable we set, e.g.: $ docker run -add-host outside:$HOST_IP -name busybox -it busybox /bin/sh (To find the IP address without using the above snippet, you can use the command ifconfig docker0). We put it in the HOST_IP shell var like so: $ HOST_IP=`ip -4 addr show scope global dev docker0 | grep inet | awk '' | cut -d / -f 1` Of course, this part is optional if you just want to paste the IP in. Get the host machine's address for the docker0 interface and put it in shell var (note that docker0 doesn't exist on macOS, scroll to the next part if you're on a Mac).

Main idea: pass in the docker0 IP address to the container via -add-host: If you're on macOS using Docker Desktop, it's easier. CLI: Using the -add-host parameter with docker run I'll show it here in two ways, one via CLI and one via docker-compose as a bonus. Docker provides a way to add hosts into your container's /etc/hosts file. Kubernetes networking works differently from plain Docker networking.Дepending on your use case, a network of type host may not work (and requires some setup). Update April 2019: This won't work for Kubernetes pods/services. If you're in the same situation, I hope I can save you some time! I ran into this need and after googling, it took me way too long to eventually find the answer in the docs. Could be for debugging, or small projects, or whatever reason. Sometimes you need to be able to connect to the host network from inside a Docker container.

NOTE: If your problem is connecting TO containers FROM a macOS host, see this post: Last tested with version Docker version 18.09.3 on Ubuntu 16.04, Debian 9 (stretch), macOS Mojave (10.14.4).
