Mac Development Ansible Playbook

This playbook installs and configures most of the software I use on my Mac for web and software development. Some things in macOS are slightly difficult to automate, so I still have a few manual installation steps, but at least it's all documented here.

Installation

Ensure Apple's command line tools are installed (xcode-select --install to launch the installer).
Install Ansible:
1. Run the following command to add Python 3 to your $PATH: export PATH="$HOME/Library/Python/3.9/bin:/opt/homebrew/bin:$PATH"
2. Upgrade Pip: sudo pip3 install --upgrade pip
3. Install Ansible: pip3 install ansible
Clone or download this repository to your local drive.
Run ansible-galaxy install -r requirements.yml inside this directory to install required Ansible roles.
Run ansible-playbook main.yml --ask-become-pass inside this directory. Enter your macOS account password when prompted for the 'BECOME' password.

Note: If some Homebrew commands fail, you might need to agree to Xcode's license or fix some other Brew issue. Run brew doctor to see if this is the case.

Use with a remote Mac

You can use this playbook to manage other Macs as well; the playbook doesn't even need to be run from a Mac at all! If you want to manage a remote Mac, either another Mac on your network, or a hosted Mac like the ones from MacStadium, you just need to make sure you can connect to it with SSH:

(On the Mac you want to connect to:) Go to System Preferences > Sharing.
Enable 'Remote Login'.

You can also enable remote login on the command line:
sudo systemsetup -setremotelogin on

Then edit the inventory file in this repository and change the line that starts with 127.0.0.1 to:

[ip address or hostname of mac]  ansible_user=[mac ssh username]

If you need to supply an SSH password (if you don't use SSH keys), make sure to pass the --ask-pass parameter to the ansible-playbook command.

Running a specific set of tagged tasks

You can filter which part of the provisioning process to run by specifying a set of tags using ansible-playbook's --tags flag. The tags available are dotfiles, homebrew, mas, extra-packages and osx.

ansible-playbook main.yml -K --tags "dotfiles,homebrew"

Overriding Defaults

Not everyone's development environment and preferred software configuration is the same.

You can override any of the defaults configured in default.config.yml by creating a config.yml file and setting the overrides in that file. For example, you can customize the installed packages and apps with something like:

homebrew_installed_packages:
  - cowsay
  - git
  - go

mas_installed_apps:
  - { id: 443987910, name: "1Password" }
  - { id: 498486288, name: "Quick Resizer" }
  - { id: 557168941, name: "Tweetbot" }
  - { id: 497799835, name: "Xcode" }

composer_packages:
  - name: hirak/prestissimo
  - name: drush/drush
    version: '^8.1'

gem_packages:
  - name: bundler
    state: latest

npm_packages:
  - name: webpack

pip_packages:
  - name: mkdocs

configure_dock: true
dockitems_remove:
  - Launchpad
  - TV
dockitems_persist:
  - name: "Sublime Text"
    path: "/Applications/Sublime Text.app/"
    pos: 5

Any variable can be overridden in config.yml; see the supporting roles' documentation for a complete list of available variables.

Included Applications / Configuration (Default)

Applications (installed with Homebrew Cask):

Packages (installed with Homebrew):

autoconf
bash-completion
doxygen
gettext
gifsicle
git
gh
go
gpg
httpie
iperf
libevent
sqlite
nmap
node
nvm
php
ssh-copy-id
cowsay
readline
openssl
pv
wget
wrk
zsh-history-substring-search

My dotfiles are also installed into the current user's home directory, including the .osx dotfile for configuring many aspects of macOS for better performance and ease of use. You can disable dotfiles management by setting configure_dotfiles: no in your configuration.

Finally, there are a few other preferences and settings added on for various apps and services.

Full / From-scratch setup guide

Since I've used this playbook to set up something like 20 different Macs, I decided to write up a full 100% from-scratch install for my own reference (everyone's particular install will be slightly different).

You can see my full from-scratch setup document here: full-mac-setup.md.

Testing the Playbook

Many people have asked me if I often wipe my entire workstation and start from scratch just to test changes to the playbook. Nope! This project is continuously tested on GitHub Actions' macOS infrastructure.

You can also run macOS itself inside a VM, for at least some of the required testing (App Store apps and some proprietary software might not install properly). I currently recommend:

UTM
Tart
