what is boxen?
STORY TIME
@jbarnette + @wfarr
None
None
developing software is harder than it used to be
our toolchains have gotten more robust
our toolchains have gotten more complicated
want to work on $anything?
better install a ruby version manager, like 8 versions of
ruby, a handful of gems to try and make the behavior remotely sane, and then pray it doesn't break
None
s/ruby/literally everything but bash/g
None
let's make it better
None

THINGS BOXEN IS
a framework
stdlib
wat
None
None
THINGS BOXEN IS NOT
nope
nope
newp
sadly, no
why should i use boxen?
FRICTION SUCKS
friction is anything that gets in the way of doing
stuff
friction is the greatest source of frustration in every organization
configuring development environments is a week-long marathon in friction
"all right, new work laptop! i wonder where that blog
post i used last time to set up ruby, python, go, and git is. hopefully it still works and by the end of the week i can start shipping."
"all right, new work laptop! i wonder where that blog
post i used last time to set up ruby, python, go, and git is. hopefully it still works and by the end of the week i can start shipping." lame
None
None
None
None
getting any part of the stack running locally should never
block someone from shipping
USS COOL STUFF
None
INCONSISTENCY SUCKS
when was the last time you knew every human was
running the same services in dev and prod?
None
"hey so my postgresql isn't working. is yours working? it
is? huh. i have no idea what's wrong."
"hey so my postgresql isn't working. is yours working? it
is? huh. i have no idea what's wrong." lame
manual audits are tedious
manual audits are error-prone
ask software instead of humans
lock every core component to the same version as in
prod
UPDATING SUCKS
"jeeeeeez the mac app store has been bugging me for
like forever! i have a billion updates... meh"
"jeeeeeez the mac app store has been bugging me for
like forever! i have a billion updates... meh" lame
maybe you use CM in dev already, but when was
the last time you updated and ran it?
SECURITY SUCKS
security is a war of attrition
bug people enough about security and they stop caring about
it
"ugh, another security thing? whatever, i have way more important
things to do"
"ugh, another security thing? whatever, i have way more important
things to do" lame
let code handle security, then inform people so they know
why the code's making changes
no surprises
BOXEN ENABLES YOU TO MAKE THESE THINGS BETTER FOR YOUR
ORG
None
what do i get?
RUNNER
boxen is run via some ruby
it collects info for facter
it checks for prerequisites and conflicts before each run
it detects certain changes post-run
it has hooks too
PUPPET
"the core"
homebrew, git, hub, gcc, rbenv, ruby 1.8.7, ruby 1.9.3, ruby
2.0.0, nvm, nodejs 0.4.x, nodejs 0.6.x, nodejs 0.8.x, nginx, .dev dns, FDE, and puppetlabs-stdlib
rbenv_gem, repository, osx_chsh, osx_login_item, boxen::project, ruby::local, mysql::database, etc.
package: homebrew, compressed_app
repository: git
service: ghlaunchd
"the library"
130+ modules on GitHub
GitHub uses ~81 of those
travis-ci
CARDBOARD
gem that simplifies creating new puppet modules, optimized for the
boxen-recommended stack
librarian-puppet, rspec-puppet, puppet-lint, etc.
PUPPET-TEMPLATE
example module using cardboard
OUR-BOXEN
template boxen project
BOXEN-WEB
small rails app to allow distributing your boxen easily, with
auth
how do i get it?
Automate Everything
boxen/boxen-web
None
how do i use it?
CLI
$ boxen # run it
$ boxen --projects # list projects Boxen knows about
$ boxen <project> # run it but include <project> in
the catalog automatically
PROJECT MANIFESTS
i want to hack on my project
# modules/projects/manifests/team.pp class projects::team { boxen::project { 'team': dotenv =>
true, mysql => true, nginx => true, ruby => '1.9.3', source => 'github/team', } }
$ boxen team warning: Setting up 'team'. This can be
made permanent by having 'include projects::team' in your personal manifest.
cloned repo nginx vhost ruby version mysql databases .env file
$ cd ~/src/team $ script/server $ open http://team.dev/
PERSONAL MANIFESTS
i want to install $x but only for me
# modules/people/manifests/wfarr.pp class people::wfarr { include minecraft }
# modules/people/manifests/wfarr.pp class people::wfarr { include zsh }
# modules/people/manifests/wfarr.pp class people::wfarr { case $::hostname { 'bender': {
include projects::all } 'scruffy': { include projects::team } default: {} } }
# modules/people/manifests/wfarr.pp class people::wfarr { git::config::global { 'alias.st': value =>
'status'; 'alias.ci': value => 'commit'; 'alias.di': value => 'diff'; 'alias.lp': value => 'log -p'; 'color.ui': value => 'true'; 'user.name': value => 'Will Farrington'; 'user.email': value => 'wfarr@github.com'; } }
# modules/people/manifests/wfarr.pp class people::wfarr { include osx::example_things }
