BE BETTER

  • wanted less frustrating environment
  • find bugs when I introduce them
  • started writing tests
  • got to run them now
  • make others run them too

Automation

  • feature as a list of smaller changes
  • push changes often
  • easy to merge in (avoiding big merges)
  • pull changes often

CONTINUOUS INTEGRATION

  • changes ready to merge in
  • tests verified all is ok
  • ship it to master
  • it's deployable when ever you want

CONTINUOUS DELIVERY

  • changes on master waiting to be deployed
  • bothered with working on other things
  • merge storms 
  • just ship it!

CONTINUOUS DEPLOYMENT

Any questions ?

We don't wanna do ops

  • we have no ops ppl or just no resources
  • we rent stuff
  • we outsource infrastructure
  • not our core bussiness

We don't wanna do ops

WE NEED TO KEEP IT HOME

  • we have infrastructure/servers + ops
  • must be behind FW
  • or just paranoid

source code management support

Works with github?

Works with BITBUCKET?

Works with GITLAB?

Works with basic git repo?

Works with *anything* you can throw at it?

Quick feedback on critical + long tests

  • not critical but nice to have tests
  • take a long time
  • testing 3rd party
  • slow browser tests
  • we want quick feedback loop

Quick feedback on critical + long tests

  • separate them 
  • run
    • critical on each push
    • nice to have from time to time

Quick feedback on critical+ long tests

Any questions on this part?

or 'Still no questions?'

Clean builds vs performance

  • clean build: no artifacts from previous runs

Clean build

  • start each build from scratch
  • takes time to setup
    • dependencies
    • data
  • they offer caching of dependencies

Dirty builds

  • just continues where last one stopped
  • reuses stuff from previous runs
  • no need to install library again (composer,npm,..)
  • can save lot of time on each build
  • dirty data
  • dirty files
  • watchout and clean it before/after build

Just continous delivery

- 1 click style

  • we can create a build from master now
  • save it somewhere
  • lets deploy it from phone using 1 button

Continuos deployment

  • we can create a build from master now
  • save it somewhere
  • lets just deploy it when tests are green

Continuos deployment

Debug build

  • instead of sending new commits with fixes
  • lets ssh into the build 
  • lets get some logs/files to check

Debug build

  • it's your server :)

Debug build

  • debug in beta (add it to .travis.yml where you want a break point)
  • add AWS S3 bucket for logs/artifacts

Debug build

  • enable ssh
  • access to logs/artifacts directly

saas warnings

  • dependencies change
  • you might need newer version of X
  • your app doesn't work with newer version of Y
  • they don't announce all changes in advance
  • shared resource
  • variations in built times

saas warnings

  • shared resource
  • variations in built times
    • can go double

saas warnings

  • you might need some ops knowledge for complicated scenarios

saas - the good parts

  • they take care of underlying infrastructure
  • scale 10x on demand
  • they notify you when other stuff is not working properly
    • github down/bug
    • amazon/heroku unavailable

self hosted - good parts

  • you can buy your own hardware
    • can buy killer CPUs/memory
  • can give each job/build more then 1 CPU

questions?

Thank you
