Install Docker on macOS 10.13.4

macos-install-docker.sh

#!/bin/bash

## Get Homebrew for Mac ( https://brew.sh ), if you already have 'brew' feel free to skip...
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

## Default driver for Docker, can be changed later
brew cask install virtualbox

## Docker cli friends
brew install docker docker-machine docker-compose boot2docker

## boot2docker will run your Docker containers
boot2docker init
boot2docker up

## Create default docker vm
docker-machine create --driver virtualbox default

# Configure your shell to use the new created Virtual Machine (put in ~/.bash_profile or ~/.zshrc.local, etc.)
eval $(docker-machine env default)

# To get the IP adress from the machine:
#   docker-machine ip default

# To get the IP adress from the machine:
#   docker-machine ip default
# Test it out by running something!
#   docker run -it --rm alpine:latest /bin/sh -c "echo Hello world"

Create docker-machines for each project if you can, handy things to add to ~/.bash_profile 😀

docker-machine create --driver virtualbox ${your-project-name}

update-docker-hosts() {
  # clear existing *.docker.local entries from /etc/hosts
  sudo sed -i '' '/\.docker\.local$/d' /etc/hosts
  # iterate over each machine
  docker-machine ls | tail -n +2 | awk '{print $1}' \
  | while read -r MACHINE; do
          MACHINE_IP="$(docker-machine ip ${MACHINE} 2>/dev/null)"
          [[ -n $MACHINE_IP ]] && sudo /bin/bash -c "echo \"${MACHINE_IP}	${MACHINE}.docker.local\" >> /etc/hosts"
          export no_proxy=$no_proxy,$MACHINE_IP
  done
  cat /etc/hosts
}

switch-docker-machine() {
  # Usage: switch-docker-machine <machine-name>
  eval "$(docker-machine env $1)"
}

Run update-docker-hosts whenever you create a new machine with docker-machine create and then switch-docker-machine when you want to switch to that env. Check which machine is active in your shell before running things like docker-compose up !
