Intro

So I needed to set up a machine for php development but rather than use a server I reckoned now would be a good time to try and set up Docker so that the server will be local, I can easily bring it up and down, change config, lightning fast and all the other things Docker promises.

Installation

Docker has the installation pretty well covered as you can imagine https://docs.docker.com/mac/

I went with the more manual option as I kind of wanted to know more about what’s going on https://docs.docker.com/engine/installation/mac/#from-your-shell

So a quick copy of what’s happening

Download and install the Docker ToolBox

Create a ‘default’ docker machine — on a Mac you need a linux base

docker-machine create --driver virtualbox default

You should now have a default machine, check with

docker-machine ls

Should give you something like

NAME      ACTIVE   DRIVER       STATE     URL   SWARM   DOCKER    ERRORS
default   -        virtualbox   Stopped                 Unknown

You then need to start it (I only have one so fairly simple)

docker-machine start

To get info on this machine

docker-machine env

Should give you something like this

export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/Users/David/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell:
# eval $(docker-machine env)

So run what it tells you to run in order to set the terminal up for docker commands

eval $(docker-machine env)

Test It

If everything worked you can test it with

docker run hello-world

Which will print a hello from Docker.

Shell Completion

So as you may know I use the ZSH shell with Oh-My-Zsh. It has command auto completion for docker. Open up your .zshrc and find the line for plugins And add docker to it, for example

plugins=(git mvn z history-substring-search docker)
