35. How about
coding runtime environment
setup?

36. PaaS

37. Demo: Heroku

38. • Generate new rails app
rails new docker-hk-meetup —database=postgresql
cd docker-hk-meetup
rails generate controller home index
• initialize git
git init
git add -A
git commit -m “initial commit”
• create a heroku app
heroku create docker-hk-meetup
• publish
git push heroku master
• available online !
heroku open

39. Heroku is awesome

40. BUT

41. you will grow to a point …

42. Expensive
Lost control
Slow

43. so How ?

44. Office
Machine
Data
Center
Cloud
Server
Heroku ?

45. I want my own server
with total control
but less hassle

46. Office
Machine
Data
Center
Cloud
Server
? Heroku
total control
but less hassle ?

47. Docker

48. Demo: Dokku

49. There are other advantages
than just automation too:

50. We still use heroku heavily.
but for some growing projects,
we start using Docker
