CloudEnv Ruby

Installing CloudEnv’s Ruby Library is easy.

$ gem install cloudenv-hq

Alternatively, you can add gem "cloudenv-hq" if you are using bundler.

Here is an example of a simple hello.rb file you could use to test CloudEnv with.

gem "cloudenv-hq"
require "cloudenv-hq"

puts ENV.fetch("FOO")

But if you run this now you would get an error:

$ ruby hello.rb
Traceback (most recent call last):
	1: from hello.rb:4:in `<main>'
hello.rb:4:in `fetch': key not found: "FOO" (KeyError)

That’s because we haven’t created the CloudEnv environment variable yet.

So the next step is initializing the app:

$ cloudenv init
Name of App: rubytest
==> SUCCESS: You have created the app 'rubytest' in CloudEnv. Try the following command next:
EDITOR=nano cloudenv edit
==> REMEMBER: You need to distribute the following file to all your team members and deployment servers
/home/lucas/rubytest/.cloudenv-secret-key

And now you can modify your environmental variables using cloudenv edit

$ cloudenv edit
FOO=bar

Finally, we can get the output we expect.

$ ruby hello.rb
bar
