Talk about provisioning iOS CI mac mini servers using Ansible. These are the slides for my presentation for Ansible London Meetup. https://www.meetup.com/Ansible-London/events/241643732/

1. Building iOS CI
Servers with Ansible
London Ansible Meetup

Twitter: Shashikant86
Github: Shashikant86
Blog: http://shashikantjagtap.net/

2. Continuous Integration: iOS

3. Static Analysis : SwiftLint

4. Build : xcodebuild

5. Test : XCTest

6. Archive : ipa

7. Upload : iTunes Connect

8. iOS Self hosted CI

9. iOS Cloud CI

10. Setting up iOS CI Server
✤ Xcode & Command Line Tools
✤ Ruby for Cocoapods and Fastlane
✤ Homebrew packages
✤ macOS Defaults
✤ CI Server Specific tasks (Jenkins, Xcode Server,
TeamCity)

11. Manually Setting up CI Server

12. Why Provisioning ?
✤ Avoid repeating manual work
✤ Say No to “Works on My Machine”
✤ Infrastructure As Code
✤ Ability to reset and reconfigure CI infrastructure

13. What Are Choices ?

14. Hello Ansible

15. Challenges
✤ It’s not Linux
✤ Proprietary Softwares from Apple
✤ Not much Ansible roles for macOS
✤ Not much Ansible modules supporting macOS
packages

16. Ansible Automates Everything

17. Provisioning Xcode Installation
---
- name: Mount Xcode XIP from hosted Server
command: bash -c "mount_smbfs //{{ ansible_env.SAMBA_USER}}:{{ ansible_env.SAMBA_PASS
}}@our_server/Applications/xcode/ ~/samba/public/"
when: xcode_dir.stat.exists == False
- name: Install Xcode from XIP file Location
command: bash -c 'open -FWga "Archive Utility" --args ~/xcode_xip/{{ xcode_src }}'
- name: Move Xcode To Application
command: bash -c 'mv ~/xcode_xip/Xcode*.app /Applications/'
- name: accept license agreement
command: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -license
accept
become: yes
become_method: sudo
- name: install additional xcode components
command: installer -pkg /Applications/Xcode.app/Contents/Resources/Packages/
XcodeSystemResources.pkg -target /
become: yes

18. Provisioning Homebrew Packages
---
- name: Ensure configured taps are tapped.
homebrew_tap: "tap={{ item }} state=present"
with_items: "{{ homebrew_taps }}"
- name: Ensure configured homebrew packages are installed.
homebrew: "name={{ item }} state=present"
with_items: "{{ homebrew_installed_packages }}"
- name: Install configured cask applications.
homebrew_cask:
name: "{{ item }}"
state: present
install_options: "appdir=/Applications"
with_items: "{{ homebrew_cask_apps }}"
when: configure_cask

19. Ruby + RVM for RubyGems
---
- name: Install RVM for the user
command: bash -c "curl -sSL https://get.rvm.io | bash
-s -- --ignore-dotfiles"
- name: Install ruby version
command: bash -c "~/.rvm/bin/rvm install
{{ ruby_version }} --with-zlib-dir={{ zlib_directory }}"
- name: Install Ruby Gems required for iOS app
developement
command: bash -c "~/.rvm/rubies/{{ ruby_version }}/
bin/gem install {{item}}"
with_items: "{{ rubygems_packages_to_install }}"

20. Provisioning macOS Defaults
---
- name: Setup macOS Sleep Mode
shell: "{{ item }}"
with_items: "{{ macos_sleep_options }}"
changed_when: false
- name: Software Updates
shell: "{{ item }}"
with_items:
"{{ macos_software_autoupdates }}"
changed_when: false

21. CI Server Specific Examples:
TeamCity
---
- name: "Download Teamcity Agent Package"
command: bash -c "curl {{ teamcity_agent_server_url }}/update/
buildAgent.zip --output /tmp/buildAgent.zip"
register: _teamcity_agent_package
- name: "Add TeamCity Agent configuration"
template:
src: "buildAgent.properties.j2"
dest: "{{ teamcity_agent_install_dir }}/conf/
buildAgent.properties"
mode: 0644
- name: Start the Teamcity Agent
command: bash -c "{{ teamcity_agent_install_dir }}/bin/
agent.sh start"

22. Example Playbook
- hosts: localhost
connection: local
xcode_src: Xcode_8.3.xip
ruby_version: ruby-2.3.0
zlib_directory: /usr/local/Cellar/zlib/1.2.11
rubygems_packages_to_install:
- bundler
teamcity_agent_install_dir: ~/TeamCity/buildAgent
teamcity_agent_server_url: https://our_teamcity_server.com
teamcity_agent_name: Our_iOS_Agent
macos_sleep_options:
- systemsetup -setsleep Never
- systemsetup -setharddisksleep Never
- systemsetup -setcomputersleep Never
macos_software_autoupdates:
- softwareupdate --schedule off
homebrew_installed_packages:
- autoconf
- openssl
- wget
homebrew_taps:
- homebrew/core
- caskroom/cask
tasks:
- include: tasks/ios_ansible.yml
