1. Hello  Ansible adventures  in  infrastructure  automa4on   from  a  developer’s  perspec4ve Shared  by  Baraa  Basata  at  self.conference  2014  in  Detroit
2. “a  radically  simple
 IT  automa4on  pla;orm
 that  makes  your  applica4ons  and  systems
 easier  to  deploy”
4. 700+  contributors “@ansible  gets  a  new  contributor  every  1.18  days”   -­‐  Michael  DeHaan,  3/28/2014
5. write  a  “playbook”  to  deploy  a  PHP  web  app
 with  zero  manual  steps   ! see  how  Ansible  helps  you  to  integrate  with  diverse  services
 share  our  automa4on  journey-­‐in-­‐progress
 with  using  Amazon  Web  Services there  are  good  tutorials  out  there.  this  is  more  of  a  show-­‐and-­‐tell.
6. let’s  meet  Ansible write  a  “playbook”  to  deploy  a  PHP  web  app
 with  zero  manual  steps  
7. a  server  farm
8. let’s  automate!
14. agentless the  servers  don’t  even  know  that  Ansible  exists.   only  the  control  machine  has  Ansible  installed.
15. a  limited  syntax embrace  constraints.   this  is  different  from  wri4ng  code.   this  is  different  from  wri4ng  second-­‐class  automa4on  code.   dev  &  ops  can  share!
16. integra4ng  diverse   services
17. dynamic  inventory when  our  inventory  is  maintained  in  another  system   ! ansible-playbook -i farm site.yml -> ansible-playbook -i ec2.py site.yml
18. yum,  apt,  homebrew,   gem add,  remove,  or  upgrade  packages  using  your  package   manager  of  choice
19. git,  subversion,  hg deploy  soYware  from  a  source  control  repository
20. get_url download  files  from  a  given  URL  onto  the  remote  hosts
21. campfire,  hipchat,  slack,   newrelic_deployment send  no4fica4ons  to  one  of  these  (and  more)  services
22. uri interact  with  any  web  service,  e.g.  to  send  no4fica4ons  or   to  trigger  other  ac4vi4es
23. integra4ng  services   ! yum,  apt,  homebrew,  gem   git,  subversion,  hg   campfire,  hipchat,  slack,  newrelic_deployment   AWS,  Google  Compute  Engine,  and  many  more  
24. our  journey
25. where  we  started,   1  year  ago
26. the  journey  begins  with   con4nuous  integra4on  (CI)
27. building  the  first  cloud   environment
28. Packer   ! a  stock  machine  image   +  our  Ansible  playbooks  for  base  machine  configura4on   -­‐>  a  custom  base  machine  image
29. con4nuously  deploying   from  CI  to  the  cloud   environment
30. launching  the  second   cloud  environment
31. CloudForma4on   ! JSON  descrip4on  of  all  AWS  resources  that  make  up  an   environment   +  our  custom  machine  images  (build  with  Ansible+Packer)   +  our  Ansible  playbooks  to  deploy  the  applica4on   -­‐>  launch  a  new  environment  with  one  click*  
32. where  we  are  now
33. it’s  never  been  easier  to   start  automa4ng
