I ❤ Gitlab CI

-- screen

What are we talking about?

--

Simple & Bold

Fully versioned along source [in a simple .gitlab-ci.yml file](https://docs.gitlab.com/ce/ci/yaml/)

Self-contained execution [using Docker](https://docs.gitlab.com/ce/ci/docker/using_docker_images.html)

Easy to setup & use [with extensive documentation](https://docs.gitlab.com/ce/ci/introduction/)

Gitlab CI @ Oodrive

Frontend team happily switched from Jenkins 1.x in 2016

no plugins [biggest Jenkins strength & weakness](https://news.ycombinator.com/item?id=17902882)

run in isolation [only environment variables are injected](https://docs.gitlab.com/ce/ci/variables/)

well integrated [with other gitlab features](https://about.gitlab.com/features/)

--

Covers various use cases

Successful for multiple pipeline types

• Single Page Applications build, release & deploy
• Components & libraries test & publish
• End2end tests scheduled executions & aggregate data
• Documentations & tasks hosted by gitlab pages

What does it look like ?

Few examples how we use Gitlab CI
