Travis Build is a library that Travis Workers use to generate a shell based build script which is then uploaded to the VMs using SSH and executed, with the resulting output streamed back to Travis.
This code base has gone through several iterations of development, and was originally extracted from Travis Worker, before taking its current form.
Running test suites
Since the specs run the generated build script, we recommend running it in a virtual machine to contain the changes. There's a Vagrantfile in this repository, so you can use Vagrant for this:
vagrant up vagrant ssh cd /vagrant bundle exec rspec spec
If you wish to just run the specs, you can just run
bundle exec rspec spec.
Use as addon for CLI
You can set travis-build up as a plugin for the command line client:
ln -s PATH_TO_TRAVIS_BUILD ~/.travis/travis-build gem install bundler bundle install --gemfile ~/.travis/travis-build/Gemfile
This will add the
compile command to travis CLI, which produces
the bash script that runs the specified job, except that the secure environment
variables are not defined, and that the build matrix expansion is not considered.
The resulting script contains commands that make changes to the system on which it is executed
/etc/resolv.conf, install software).
sudo privileges and they are not easily undone.
It is highly recommended that you run this on a virtual machine.
The command can be invoked in 3 ways:
Without an argument, it produces the bash script for the local
travis-buildis unable to expand these keys correctly).
$ travis compile
With a single integer, it produces the script for the given build (or the first job of that build matrix).
$ travis compile 8
With an argument of the form
M.N, it produces the bash script for the job
$ travis compile 351.2
The resultant script can be used on a (virtual) machine that closely mimics Travis CI's build environment to aid you in debugging the build failures.
Raw CLI script
In addition to the travis CLI plugin you can also run the standalone CLI script:
bundle exec script/compile < payload.json > build.sh
