# Travis CI



[Travis CI](https://travis-ci.com) is a hosted continuous integration and

deployment system. You can now test and deploy open source and private projects

on [travis-ci.com](https://travis-ci.com)! You can read more about this change 

[here](https://blog.travis-ci.com/2018-05-02-open-source-projects-on-travis-ci-com-with-github-apps).



## Move to Forum



We are moving to our new community forum: [Travis CI Community](https://travis-ci.community)! As part of this move, we’ll be able to better follow and reply to threads, along with making it easier for you to find solutions and answers.  We’ll be making our best efforts to answer currently existing threads, or directing them to the new community forum.

## Documentation



Documentation for the Travis CI project can be found at

.



## Other repositories



Travis CI consists of many different sub-projects. The main ones are:



### travis-api



[travis-api](https://github.com/travis-ci/travis-api) is the Sinatra app that's

responsible for serving our API. It responds to different HTTP endpoints and

runs services in [travis-core](#travis-core). Very little logic is in this

repository.



### travis-build



[travis-build](https://github.com/travis-ci/travis-build) creates the build

script for each job. It takes the configuration from the `.travis.yml` file and

creates a `bash` script that is then run in the build environment by

[travis-worker](#travis-worker). This repository also hosts the source for

[language-specific scripts](https://github.com/travis-ci/travis-build/tree/master/lib/travis/build/script).



### travis-cookbooks



[travis-cookbooks](https://github.com/travis-ci/travis-cookbooks) holds the

[Chef](https://docs.chef.io/index.html) cookbooks that are used to provision the build environments.



### travis-hub



[travis-hub](https://github.com/travis-ci/travis-hub) collects events from

other apps and notifies other apps about the events. For example, it notifies

[travis-tasks](#travis-tasks) about builds starting and finishing so

notifications can be sent out.



travis-hub is also responsible for enqueueing jobs that have been created and

enforcing the Quality of Service restrictions, such as the number of concurrent

builds per user.



### travis-listener



[travis-listener](https://github.com/travis-ci/travis-listener) receives

notifications from GitHub whenever commits are pushed or pull requests are

opened. They are then pushed onto RabbitMQ for other apps to process.



### travis-logs



[travis-logs](https://github.com/travis-ci/travis-logs) receives log updates

from [travis-worker](#travis-worker), saves them to the database and pushes

them to the [web client](#travis-web). When a job is finished, travis-logs is

responsible for pushing the log to Amazon S3 for archiving.



### travis-support



[travis-support](https://github.com/travis-ci/travis-support) holds shared

logic for the different Travis CI apps. It is different from travis-core in

that it holds more generic things, like how to run an async job or how to

handle exceptions.



### travis-tasks



[travis-tasks](https://github.com/travis-ci/travis-tasks) receives

notifications from [travis-hub](#travis-hub) and sends out notifications to the

different notification providers as needed.



### travis-web



[travis-web](https://github.com/travis-ci/travis-web) is our main Web client.

It is written using [Ember](http://emberjs.com) and communicates with

[travis-api](#travis-api) to get information and gets live updates from

[travis-hub](#travis-hub) and [travis-logs](#travis-logs) through

[Pusher](https://pusher.com/).



### travis-worker



[travis-worker](https://github.com/travis-ci/worker) is responsible for

running the build scripts in a clean environment. It streams the log output to

[travis-logs](#travis-logs) and pushes state updates (build starting/finishing)

to [travis-hub](#travis-hub).
