As per the documentation from docker, there are certain limitation in Mac OS environment where we cannot expose ports from docker container to host machine, as it is running on a virtual machine.

If you do not want to communicate outside docker but if you want to connect to different images inside a same docker container or different docker container you can use network-mode to host.

network_mode: "host"

But what if we need to expose outside docker to the host machine where the docker is running?

As a workaround we may need to create a loopback IP address in Mac OS host machine. To do this,

1. create a file in your current directory named loopback-alias.plist and place below content. Here I’ve used 10.200.10.1 as a loopback IP address. But you can modify it if you want.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist>
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>loopback-alias</string>
        <key>ProgramArguments</key>
        <array>
                <string>/sbin/ifconfig</string>
                <string>lo0</string>
                <string>alias</string>
                <string>10.200.10.1</string>
                <string>netmask</string>
                <string>255.255.255.0</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
</dict>
</plist>

2. And then run below commands in order to make it available when startup

sudo cp loopback-alias.plist /Library/LaunchDaemons/loopback-alias.plist
sudo launchctl load -w /Library/LaunchDaemons/loopback-alias.plist

3. In order to take this effect either you can restart your system or simply restart the network as follows

networksetup -setairportpower en0 off && networksetup -setairportpower en0 on

Changes at docker-compose.yml

redis:
	image: redis
	expose: 
		- '6379'
	ports: 
		- '10.200.10.1:6379:6379'
	extra_hosts: 
		- 'localhost:10.200.10.1'

This means, we are using hosts loopback IP where we are exposing the port. And you can access it from your host machine as follows,

http://10.200.10.1:6379

Similarly we can add same configuration to any images to access it from host machine.

You may need to add the following to your bashrc/zshrc for MacOS

export DOCKER_HOST=unix:///var/run/docker.sock
