macOS Setup

This page contains directions for setting up a development environment for EDD on macOS.

XCode

Macs have tools for development freely available, but these tools are not installed by default. To ensure the necessary utilities are installed, get XCode from the App Store. After launching the XCode app, you should be prompted to install additional components. With macOS 10.12 “Sierra” or later, the utilites used by EDD can be installed by running xcode-select --install from the Terminal.

Homebrew

Homebrew is a package manager for OS X. The Homebrew packages handle installation and dependency management for Terminal software. The Caskroom extension to Homebrew does the same for GUI applications. There is a Brewfile in the root of the EDD repository that defines the software used for EDD development.

To install, run the below command in Terminal, and follow the prompts.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After installing Homebrew, the brew command will be available to run in Terminal. Running brew doctor should say Your system is ready to brew. or describe any problems with the install. Then use Homebrew to install tools for EDD with this command:

brew bundle

It is a good idea to occaisionally run brew update to refresh Homebrew’s list of available packages and versions; and run brew upgrade to install updated versions of your installed Homebrew packages.

Docker

Docker is a container virtualization platform: all software, configuration, and dependencies required to run a service are packaged into standalone images. These images are ready to run immediately upon being copied to a new host running a Docker daemon. Docker is installed with the Brewfile in the previous section.

Verify that Docker is installed and setup correctly by running:

docker run --rm hello-world

If you get:

docker: command not found

That means Docker was not successfully installed from Homebrew. Try getting the Docker for Mac installer directly from the Docker project. The related docker-compose utility manages launching multiple services in multiple containers, based on a configuration file. Running the docker-compose command should display some help text describing the options for using the tool. If you do not see this help, try re-installing Docker for Mac.

Resources available for Docker containers are set in the Docker menu Preferences, under the Advanced tab. It is recommended to allocate at least 2 CPU cores and 4 GB RAM to Docker. Click the Apply & Restart button to restart Docker with updated resource allocations.
