5000
● Language specific files
○ Heroku Buildpacks
detects the language
○ Python ->
requirements.txt
○ Ruby -> Gemfile

● Runs appropriate tests
● Uses
○ Herokuish
○ Heroku buildpacks
● Some automatically detected
languages
○ Ruby
○ Nodejs
○ Python
○ Java
● Tests included in application
12. Auto Review Apps
● Temporary application
developments for branches
● Review app for each branch
○ <branch-name>.example.com
● Deleted when branch deleted
● Requires Kubernetes cluster
○ No cluster -> no review apps
13. Auto Deploy
● Deploy master branch to production,
and staging in Kubernetes
○ Staging:
<project-name>-staging.example.com
○ Production:
<project-name>-production.example.com
● Allows
○ Automatic production deployment
○ Manual production deployment
○ Rollout production deployment
● Deployment strategy options
