Recently, I spent around 14 to 16 hours learning all of the necessary steps to getting an existing repo set up with Travis CI to run unit tests, and then once successful, connect to a remote server that isn't a PaaS (in this case, Linode) and then proceeds to use Git hooks to do post deployment things.
Starting with your local machine and you have your project already checked out from Github.
- Assuming you have Ruby (at least 2.3.1) installed, run
gem install travis. This installs the Travis CI command-line tools. We're going to use these tools to encrypt RSA keys that Travis will use to connect to your remote server. - This tutorial also assumes that you have a working repo and a Travis-CI account set up.
