Travis/Travis-build

From charlesreid1

Main Travis page: Travis

Use travis-build (travis-convert?) as a travis.yml to build.sh converter: https://github.com/travis-ci/travis-build

Use travis-build to convert travis.yml to travis.sh

To use travis-build you need ruby stuff.

UGH I HAAAAAAAATE RUBY.

Attempt... 3? 4?

All of this happens in a Docker image (e.g., travis-garnet): 

$ git clone https://github.com/travis-ci/travis-build
$ cd travis-build

Now install ruby 2: 

$ apt-add-repository ppa:brightbox/ruby-ng
$ apt-get update
$ apt-get install ruby2.2 ruby2.2-dev

Now install the rake file to build this crap: 

$ bundle install
$ bundle exec rake

Nope. At this point I have no clue how to install travis-build.

Attempt 5

Via https://stackoverflow.com/questions/34052460/how-to-build-install-travis-build

git clone the repo into some persistent directory (~/GitHub)

from ~/GitHub/travis-build run ln -s $(pwd) ~/.travis/travis-build (taken almost verbatim from the README)

After running travis (no arguments) - oh wait, there IS no travis command.

Attempt 6

Okay, let's just try and install Travis. 

root@01a7a68152ad:/# gem install travis -v 1.8.8 --no-rdoc --no-ri

Building native extensions.  This could take a while...

Nope.

Attempt 7

Tried this: 

$ git clone https://github.com/travis-ci/travis-build
$ cd travis-build
$ docker-compose up

Should have been: 

$ git clone https://github.com/travis-ci/travis-build
$ cd travis-build
$ docker-compose build
$ docker run -ti travisbuild_web /bin/bash

aaaaand no way to use travis-build: 

root@294c95445521:/usr/src/app# travis convert
unknown command convert

More tries: 

root@294c95445521:/usr/src/app# bundle exec rake

Attempt 8

Start over - build the travis-build Docker image: 

$ git clone https://github.com/travis-ci/travis-build
$ cd travis-build
$ docker-compose up

Now follow the instructions on the README: 

root@294c95445521:/usr/src/app# mkdir -p ~/.travis
root@294c95445521:/usr/src/app# ln -s ${PWD} ~/.travis/travis-build
root@294c95445521:/usr/src/app# gem install bundler
root@294c95445521:/usr/src/app# bundle install --gemfile ~/.travis/travis-build/Gemfile
root@294c95445521:/usr/src/app# bundler binstubs travis --force

Bingo, now we have a convert command: 

root@294c95445521:/usr/src/app# travis

run `/usr/local/bundle/bin/travis help COMMAND` for more infos

Now... it took a lot of work to figure out how to USE IT: 

# travis compile -r numpy > build.sh

Then there's the task of getting the thing out of the container. Had to restart the container with a shared volume (-v flag) and run the whole process again.

Submitted a github pull request to help improve the vague documentation.
