Installing rbenv, ruby, bundler on Bamboo

The following details how to install rbenv, ruby, bundler on a RHEL / CentOS Bamboo build agent.

On the bamboo agent/server machine, bamboo.example, install rbenv as per its docs:

yum install -y openssl-devel readline-devel zlib-devel
su - bamboo
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
cd ~/.rbenv && src/configure && make -C src
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
exit

su - bamboo
type rbenv # this should return with "rbenv is a function"

Now, install the ruby-build plugin for rbenv as per its docs:

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

Now, install version 2.1.9 of ruby (or the desired version) as per the rbenv ruby install instructions (the version of Ruby bundled with PE 2016.2.0 - see https://docs.puppet.com/pe/2016.2/overview_version_table.html ) ie:

rbenv install -l       # lists out all versions of ruby known to ruby-build
rbenv install 2.1.9    # this downloads the ruby 2.1.9 source, compiles and installs it under ~bamboo/.rbenv/versions/
rbenv rehash           # this sets up shims for all executables in ruby and ruby gems known to rbenv
rbenv global 2.1.9     # this sets ruby 2.1.9 as the default ruby to run
ruby --version         # you should see "ruby 2.1.9p490 (2016-03-30 revision 54437) [x86_64-linux]"

Install the bundler ruby gem:

gem install bundler

Add executable "bundle" to Bamboo

We'll add the executable ~/.rbenv/shims/bundle to Bamboo. This lets rbenv decide which version of ruby to run its bundler.

Add two tasks to the control-repo plan:

• command: bundler, arguments: install (will run bundle install)
• command: bundler, arguments: exec onceover run spec (will run bundle exec onceover run spec)

Add ssh key for bamboo user to puppetserver user in bitbucket:

su - bamboo
ssh-keygen -t dsa
-> Generating public/private dsa key pair.
-> Enter file in which to save the key (/opt/atlassian/bamboo/home/.ssh/id_dsa):


Accept the stash host key:
su - bamboo
git clone --mirror ssh://[email protected]:7999/pup/control-repo.git /tmp/control-repo.git # enter ‘yes’ and return

Add more tasks to the plan using the Bundler executable:

• command: bundler, argument: exec rake syntax (will run: bundle exec rake syntax)
• command: bundler, argument: exec rake validate_ruby
• command: bundler, argument: exec rake profile_spec
