How to run travis-ci locally

Question

I ve just joined a project  and I m new to travis-ci   I d rather not have to push every little change to  travis yml and every little change I make to the source in order to run the build   With jenkins you can download jenkins and run locally   Does travis offer something like this   Note  I ve seen the travis-ci cli and downloaded it  but all it seems to do is call their API  which then connects to my GitHub repo  so if I don t push  it won t matter that I restart the last build

Similar to Scott McLeod s but this also generates a bash script to run the steps from the  travis yml   Troubleshooting Locally in Docker with a generated Bash script    choose the image according to the language chosen in  travis yml   docker run -it -u travis quay io travisci travis-jvm  bin bash    now that you are in the docker image  switch to the travis user sudo - travis    Install a recent ruby  default is 1 9 3  rvm install 2 3 0 rvm use 2 3 0    Install travis-build to generate a  sh out of  travis yml cd builds git clone https   github com travis-ci travis-build git cd travis-build gem install travis   to create    travis travis version ln -s  pwd     travis travis-build bundle install    Create project dir  assuming your project is  AUTHOR PROJECT  on GitHub cd   builds mkdir AUTHOR cd AUTHOR git clone https   github com AUTHOR PROJECT git cd PROJECT   change to the branch or commit you want to investigate travis compile  gt  ci sh   You most likely will need to edit ci sh as it ignores matrix and env bash ci sh

Travis-ci offers a new container-based infrastructure that uses docker    This can be very useful if you re trying to troubleshoot a travis-ci build by reproducing it locally   This is taken from Travis CI s documentation   Troubleshooting Locally in a Docker Image  If you re having trouble tracking down the exact problem in a build it often helps to run the build locally  To do this you need to be using our container based infrastructure  ie  have sudo  false in your  travis yml   and to know which Docker image you are using on Travis CI   Running a Container Based Docker Image Locally   Download and install the Docker Engine  Select an image from Docker Hub  If you re not using a language-specific image pick ci-ruby  Open a terminal and start an interactive Docker session using the image URL   docker run -it travisci ubuntu-ruby 18 04  bin bash  Switch to the travis user   su - travis  Clone your git repository into the   folder of the image  Manually install any dependencies  Manually run your Travis CI build command

This process allows you to completely reproduce any Travis build job on your computer  Also  you can interrupt the process at any time and debug  Below is an example where I perfectly reproduce the results of job  191 1 on php-school cli-menu    Prerequisites   You have public repo on GitHub You ran at least one build on Travis You have Docker set up on your computer   Set up the build environment  Reference  https   docs travis-ci com user common-build-problems    Make up your own temporary build ID  BUILDID  build- RANDOM   View the build log  open the show more button for WORKER INFORMATION and find the INSTANCE line  paste it in here and run  replace the tag after the colon with the newest available one    INSTANCE  travisci ci-garnet packer-1512502276-986baf0   Run the headless server  docker run --name  BUILDID -dit  INSTANCE  sbin init  Run the attached client  docker exec -it  BUILDID bash -l    Run the job  Now you are now inside your Travis environment  Run su - travis to begin   This step is well defined but it is more tedious and manual  You will find every command that Travis runs in the environment  To do this  look for for everything in the right column which has a tag like 0 03s     On the left side you will see the actual commands  Run those commands  in order   Result  Now is a good time to run the history command  You can restart the process and replay those commands to run the same test against an updated code base    If your repo is private  ssh-keygen -t rsa -b 4096 -C  YOUR EMAIL REGISTERED IN GITHUB  then cat    ssh id rsa pub and click here to add a key FYI  you can git pull from inside docker to load commits from your dev box before you push them to GitHub If you want to change the commands Travis runs then it is YOUR responsibility to figure out how that translates back into a working  travis yml  I don t know how to clean up the Docker environment  it looks complicated  maybe this leaks memory

You could try Trevor  which uses Docker to run your Travis build  From its description   I often need to run tests for multiple versions of Node js  But I don t want to switch versions manually using n nvm or push the code to Travis CI just to run the tests  That s why I created Trevor  It reads  travis yml and runs tests in all versions you requested  just like Travis CI  Now  you can test before push and keep your git history clean

Use wwtd  what would travis do  ruby gem to run tests on your local machine roughly as they would run on travis   It will recreate the build matrix and run each configuration  great to sanity check setup before pushing   gem i wwtd wwtd

I m not sure what was your original reason for running Travis locally  if you just wanted to play with it  then stop reading here as it s irrelevant for you   If you already have experience with hosted Travis and you want to get the same experience in your own datacenter  read on   Since Dec 2014 Travis CI offers an Enterprise on-premises version   http   blog travis-ci com 2014-12-19-introducing-travis-ci-enterprise   The pricing is part of the article as well      The licensing is done per seats  where every license includes 20 users  Pricing starts at  6 000 per license  which includes 20 users and 5 concurrent builds  There s a premium option with unlimited builds for  8 500

I wasn t able to use the answers here as-is   For starters  as noted  the Travis help document on running jobs locally has been taken down   All of the blog entries and articles I found are based on that   The new  quot debug quot  mode doesn t appeal to me because I want to avoid the queue times and the Travis infrastructure until I ve got some confidence I have gotten somewhere with my changes  In my case I m updating a Puppet module and I m not an expert in Puppet  nor particularly experienced in Ruby  Travis  or their ecosystems   But I managed to build a workable test image out of tips and ideas in this article and elsewhere  and by examining the Travis CI build logs pretty closely  I was unable to find recent images matching the names in the CI logs  for example  I could find travisci ci-sardonyx  but could not find anything with  quot xenial quot  or with the same build name    From the logs it appears images are now transferred via AMQP instead of a mechanism more familiar to me  I was able to find an image travsci ubuntu-ruby 16 04 which matches the OS I m targeting for my particular case   It does not have all the components used in the Travis CI  so I built a new one based on this  with some components added to the image and others added in the container at runtime depending on the need  So I can t offer a clear procedure  sorry   But what I did  essentially boiled down   Find a recent Travis CI image in Docker Hub matching your target OS as closely as possible   Clone the repository to a build directory  and launch the container with the build directory mounted as a volume  with the working directory set to the target volume  Now the hard work  go through the Travis build log and set up the environment   In my case  this meant setting up RVM  and then using bundle to install the project s dependencies   RVM appeared to be already present in the Travis environment but I had to install it  everything else came from reproducing the commands in the build log   Run the tests   If the results don t match what you saw in the Travis CI logs  go back to  3  and see where to go   Optionally  create a reusable image   Dev and test locally and then push and hopefully your Travis results will be as expected    I know this is not concrete and may be obvious  and your mileage will definitely vary  but hopefully this is of some use to somebody   The Dockerfile and a README for my image are on GitHub for reference

UPDATE  I now have a complete turnkey  all-in-one answer  see https   stackoverflow com a 49019950 300224  Only took 3 years to figure out   According to the Travis documentation  https   github com travis-ci travis-ci there is a concoction of projects that collude to deliver the Travis CI web service we know and love  The following subset of projects appears to allow local make test functionality using the  travis yml in your project   travis-build  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-cookbooks  travis-cookbooks holds the Chef cookbooks that are used to provision the build environments   travis-worker  travis-worker is responsible for running the build scripts in a clean environment  It streams the log output to travis-logs and pushes state updates  build starting finishing  to travis-hub    The other subprojects are responsible for communicating with GitHub  their web interface  email  and their API

It is possible to SSH to Travis CI environment via a bounce host  The feature isn t built in Travis CI  but it can be achieved by the following steps    On the bounce host  create travis user and ensure that you can SSH to it  Put these lines in the script  section of your  travis yml  e g  at the end    - echo travis  sshpassword   sudo chpasswd - sudo sed -i  s ChallengeResponseAuthentication no ChallengeResponseAuthentication yes    etc ssh sshd config - sudo service ssh restart - sudo apt-get install sshpass - sshpass -p  sshpassword ssh -R 9999 localhost 22 -o StrictHostKeyChecking no travis  bouncehostip   Where  bouncehostip is the IP host of your bounce host  and  sshpassword is your defined SSH password  These variables can be added as encrypted variables  Push the changes  You should be able to make an SSH connection to your bounce host    Source  Shell into Travis CI Build Environment     Here is the full example     use the new container infrastructure sudo  required dist  trusty  language  python python   2 7   script  - echo travis  sshpassword   sudo chpasswd - sudo sed -i  s ChallengeResponseAuthentication no ChallengeResponseAuthentication yes    etc ssh sshd config - sudo service ssh restart - sudo apt-get install sshpass - sshpass -p  sshpassword ssh -R 9999 localhost 22 -o StrictHostKeyChecking no travisci  bouncehostip   See  c-mart travis-shell at GitHub     See also  How to reproduce a travis-ci build environment for debugging
