TravisExperiment

A little experiment with Travis CI features and capabilities.

Goals:

• Enable Travis CI to work with multiple projects in different languages, all in a single repo
• Deploy to a generic server using SSH
• Hide server IP address

What I learned:

• Currently for the "script" providers, there can only be 1 command in the "script" section

  Otherwise deploy fails with something like /home/travis/.rvm/gems/ruby-2.2.7/gems/dpl-1.9.7/lib/dpl/cli.rb:54:in `system': wrong first argument (ArgumentError)
• Environment variables can be encrypted in two ways:

  travis encrypt <VAR_NAME>=<VAR_VALUE> and travis encrypt <VAR_VALUE>

  First way doesn't seem to work with the ssh_known_hosts section, so use the second way and insert the result as shown in .travis.yml here.
