We don't wanna do ops

• no ops person/team
• no resources?
• we rent stuff
• we outsource infrastructure
• not our core business

We don't wanna do ops

WE NEED TO KEEP IT HOME

• own infrastructure/servers
• have ops person/team?
• must be behind FW
• or just paranoid

WE NEED TO KEEP IT HOME

Jenkins

• open source CI server
• easy to install
  • setup <1hour
• will need some plugins

but...

enterprise on-premise 

jump on quickly

• small company/team/solo dev
• code is on a private github repo
• painless dive into world of automation
• just wanna check "continuous *"

jump on quickly

Setup Circle ci

• registration takes <1min
  • uses Github OAuth 
• adding new project <1min
  • 3 clicks

Add circle.yml

Circle CI

pricing

• private projects
  • 1 container free
  • $50 per container/month
• public projects
  • 4 containers free
  • $50 per container/month

Multiple versions

• test same code using multiple language versions
• or different databases
• or ...

Multiple versions

We have our own orm

• need to test it against multiple versions of PHP
• and different databases

Setup TRAVIS ci

• registration takes <1min

  • $129 for 2 concurent jobs
  • $249 for 5 concurent jobs
  • $489 for 10 concurent jobs
• public projects

Travis ci

public vs private repos

• separate web sites
• waiting queue time on private < public

Customizable JOBS

• multiple jobs inside one build
• each prepared differently
  • code quality check
  • browser tests

CUSTOMIZABLE JOBS

Customizable Builds

• multiple builds on each push
• or in pipeline
  • when X finishes, start Y

Customizable Builds

PARALLELIZE TESTS

• tests take lot of time
• automatic 'sharding' across nodes

PARALLELIZE TESTS

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

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/files
• problems with paralelization
• 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 
• save logs/artfacts

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

saas warnings

• shared resource
• variations in built times

saas warnings

• you might need some ops knowledge for complicated scenarios
