Netflix’s approach to open source

Form a small cross-functional team working group that centralizes OSS competence, assisting decentralized teams working with OSS spend less time focusing on the administrative aspects (legal, tooling, branding, monitoring, and community promotion).

Open source enabler - OSS Interest Group

● Internal mailing list● Meets once per month● Topics from developers● Help each other with

common problems

Trivia

How many OSS projects does Netflix have?

a) 59b) 102c) 176

Answer

176

Netflix (119) Spinnaker (17) nebula-plugins (40)

Open Source Shepherds

● Management with business context

● Consistency across related projects

● Document how area fits together

● Focus on OSS health of each area

Common tools accelerate developers

● Security● Backup● Github user/group repo management● Project tracking● Build systems● CI systems

Security tools

● We scan code for○ Access keys, credentials, email

addresses, hostnames● Provide tools and automation to

○ Scan before initial release○ Scan repeatedly on github

Source code management

● Backup and archival○ Github down != Netflix down

● Internal mirrors we could build from

Project Ownership

All projects have● Development lead, Management lead● Shepherd from OSS function areaOnly projects with active leads stay active!

Github management

● Has to be easy○ Otherwise, teams will go it alone

● Has to be automated○ Self service - chat ops○ Following secure best practices

Github user managementSupport bring github id● User links to internal id● All tools then can

associate identity

Two Factor Auth Enforcement● Automation to boot users who don’t● Be careful - education on recovery!

Github group management

● Owners○ Limited group - due to power○ Automate via chatops all owner actions

● Netflixer group○ Full write permissions on all repos

● Outside contributors○ Added by netflixers, validated over time

Github automated through chat ops

Overall Org Health Tracking

Metrics we track

● Issues○ open, closed, TTC

● Pull Requests○ open, closed, TTC

● Last commit timing● Stars/forks● Num contributors

Project Health Tracking

github.com/Netflix/

OSSTracker

● Repeatable builds● deb/rpm files for OS

package baking● Reduces boilerplate for

common best practices● Standards for

release/version mgmt

Common Build For Gradle/Java

nebula-plugins.github.io

Common CI Systems

● Travis CI○ Populate .travis.yml and sh files○ Standard targets for snapshots,

candidates, and releases○ Binary upload credentials handled○ Consistency across projects

● Cloudbees○ Job-dsl to create release jobs

Using Docker to make projects easier

● A running image is worth a thousand wiki documents

● Started with ZeroToDocker○ Monolithic solution○ Leveraged Dockerhub

TODO Group

● Joined 2015● Collaborate on how

to better collaborate● Leverage TODO group’s work

○ Github focus○ Automation innovations

● Good group for helping OSS companies
