3. My first “dev” job
Hired to convert PSDs to HTML

4. My first “dev” job
Hired to convert PSDs to HTML
Ended up building / hacking at web
apps

5. My first “dev” job
Hired to convert PSDs to HTML
Ended up building / hacking at web apps
We had no DevOps (was it even a thing then?)

6. My first “dev” job
Hired to convert PSDs to HTML
Ended up building / hacking at web apps
We had no DevOps (was it even a thing then?)
We invested in metal

7. My first “dev” job
Hired to convert PSDs to HTML
Ended up building / hacking at web apps
We had no DevOps (was it even a thing then?)
We invested in metal
Just started using “the cloud”

8. My second dev job
Yay I'm not alone!

9. My second dev job
Yay I'm not alone!
I was still "the server person"

10. Yay I'm not alone!

Scaling a team
We needed to scale up (and skill up)
our team
My second dev job

11. Scaling a team
Version control is NOT renaming files
Version control EVERYTHING

16. Trial & Error is ok!

17. Scaling a team
Stop Editing In
Production!

18. No more edit
&
uploading!
Everything
goes into
version control!

19. Disable FTP Access*!
# echo troy >> /etc/ftpuser
# echo andy >> /etc/ftpuser
# echo joe >> /etc/ftpuser
Better yet, disable FTP completely*

20. *If you can

21. Scaling a team
Development environments

22. MAMP, LAMP, WAMP, WAT?
Mac/Linux/Windows Apache MySQL PHP
These are all great tools

23. Do you deploy to
MAMP/WAMP?

24. Why develop on a
different configuration?

25. Catch those environment
bugs earlier

26. Remove the phrase
“…It works on my machine…”
From your team

27. Or learn the phrase
“We’re putting your
machine into production”

28. Stop using WAMP/MAMP
and start using Vagrant!

29. Virtualbox
VMware Fusion & Desktop
Parallels Desktop
Virtual Machine Providers

30. API Magic

31. Runs Anywhere (almost)

32. Vagrant allows you to:
•Create a server
•Configure a server
•Delete a server
…over and over and over..

33. What’s a box?

34. Not sure how to create a
Vagrant box?

37. What’s in Homestead
•Ubuntu 16.04
•PHP 7.1
•Nginx
•MySQL
•MariaDB
•Sqlite3
•Postgres
•Composer
•Yarn
•NodeJS
•Bower
•Grunt
•Gulp
•Beanstalkd
•Memcached
•Redis

38. What if Homestead doesn’t
fit your application?

39. PuPHPet.com

40. Guided path to create your own Vagrant
Supports common Distributions
Customize users, firewall rules, cron jobs
Add databases, virtual hosts
Supports Ruby, PHP, Python, NodeJS,
HHVM
Beanstalkd & RabbitMQ
Elastic Search & Apache Solr
PuPHPet.com

41. PuPHPet.com
Great for learning HOW to build boxes
Especially useful if you’d like to learn Puppet

42. Other Provisioners
Shell
Chef - use existing Cookbooks
Docker - used if your app is in Docker
SaltStack

43. Vagrant Cookbook

44. Ansible for DevOps

45. Vagrant is so 2013!
CONTAINERS!

48. Learning Budget

49. Learning Budget

50. Scaling a team
Test your code!
Testing was the hardest part for us.
The payoffs in catching regression bugs and
confidence in our deployments was well worth it

51. Is your code testable?
If unit testing is hard, your code may
not have been written to be testable.

52. Testing Resources

53. Testing Resources
https://laracasts.com/skills/testing

54. Continuous Integration
Continuous Delivery

55. Continuous Integration
Frequently integrate code changes into the existing
code repository
Merging branches to master/production
Automated build tests to ensure issues found
quickly
Does not have to be deployed

56. Continuous Delivery
Produce valuable changes in code in short cycles to be
released at any time.
AKA: Continuous Deployment
Automated build tests to ensure issues found quickly
Deployment happens on successful build

57. Which is right for you?
Your goal should be Continuous Integration (at least!)
Strive for Continuous Delivery if it makes sense
Applications with a live event component may not be
suited for Continuous Delivery

59. There are a lot of CI
solutions out there

60. Getting CI Working

61. What is your process?

62. Create your workflow

63. Optimize your time
in the console

64. Work smarter not harder

65. Stop typing the same commands
git status
git pull origin master
git branch —set-upstream-to=origin/master
vagrant global-status | grep running
redis-server /usr/local/etc/redis.conf
php -S localhost:8000
ssh svpernova@joeferguson.me -t screen -dR irc
gs
gpm
gsu
vgr
startredis
startphp
irc

66. Make use of aliases
alias gs=“git status”
alias gpm=“git pull origin master”
alias gsu=“git branch —set-upstream-to=origin/master”
alias vgr=“vagrant global-status | grep running”
alias startredis=“redis-server /usr/local/etc/redis.conf”
alias startphp=“php -S localhost:8000”
alias irc=“ssh svpernova@joeferguson.me -t screen -dR irc"

67. Use Screen for long
running processes
https://www.mattcutts.com/blog/a-quick-tutorial-on-screen/

68. Think of screen as a detachable
window that contains your console

69. Screen Demo

70. Want more Power?

71. Bash isn’t the only shell!

72. http://ohmyz.sh
Uses zsh
180+ Plugins
700+ Contributors
140+ Themes

73. Customize your shell
• Local IPs
• Date
Green Text
because this is
the local machine
• User
• Hostname
• Current Path
• Current time

74. Customize your shell
• User
• Hostname
• Current Path
• Current time
• Local IPs
• Date
Red Text
because this is
a remote machine

75. Customize your shell
Tab completion on steroids
+ Git branch info because we are in a repo

76. Tab Completion Demo

77. .zshrc

78. Automate Common Tasks
Alias long commands
Shell script sequential commands
Use cron to run your scripts at
specific times
Create installers for your settings

79. Version Control Configs

80. Do NOT version control
your SSH keys!

81. Do NOT version control
your API keys!

82. Recap
Version Control everything you can
Create a process that works for your team
Practice how you play
Test everything you can
Automate everything you can
