Ey::Core

Official Engine Yard Core API Ruby client and CLI utility.

Installation

Add this line to your application's Gemfile:

gem 'ey-core'

And then execute:

$ bundle

Or install it yourself for ad-hoc or CLI usage:

$ gem install ey-core

Usage

There are two ways to use this gem: you can install it to use as a client library for writing your own Engine Yard Cloud integrations, or you can use the ey-core CLi app to use our curated integrations.

CLI Usage

The CLI app, ey-core, is the replacement for the ey command that was provided by the now mostly deprecatedengineyard gem. The old gem is still updated as need be, but is effectively just a slightly different UI for the ey-core command. Like the git command, ey-core is like a gateway to other commands.

Rather than attempting to provide an exhaustive writeup of all of the commands provided by ey-core, this document will instead describe what are likely the most common use cases and leave you to read up on the remainder via the help command.

Use Case: Getting Help

Arguably the most important command in the app is ey-core help. Given no arguments, it provides the list of second-level commands avaiable for use. From that point, each argument is expected to be a command from the next level of the hierarchy.

For example, if one wishes to learn about the servers second-level command, they would do ey-core help servers.

For commands in even deeper levels, one just adds each level of chain after the help command. Try this in your terminal: ey-core help recipes apply

Use Case: Deploying An App

The ey-core deploy command allows one to deploy a new revision of an existing application in an existing environment. The command itself has several options, some of which may or may not be required depending on several factors. To guarantee the best result and remove a good deal of uncertainty in the process, we've opted to describe a somewhat verbose invocation of the command in this document.

Let's start with some assumptions:

  • The name of our Engine Yard account is MyAwesomeCompany (you can get a real account name with ey-core accounts)
  • That account has an environment named awesome_production (you can get a real environment name with ey-core environments)
  • That account has an application named awesome_app (you can get a real application name with ey-core applications)
  • The aforementioned application is already associated with the environment

As mentioned, some of the options for the deploy command are optional, and all of the topics discussed in our assumptions are effectively optional. That said, we suggest specifying all of these options to ensure absolutely that the proper application is deployed to the proper environment in the proper account.

All that said, to deploy the application to its latest git ref and the same migration command as the last deployment, you would issue the following command:

$ ey-core deploy --account MyAwesomeCompany --environment awesome_production --app awesome_app

You can also specify a git ref to use if you'd like to deploy a specific version or branch of the app:

$ ey-core deploy --account MyAwesomeCompany --environment awesome_production --app awesome_app --ref feature/new-ui

Say that you want to change the way your migrations are run during the deploy. You can specify the migration command:

$ ey-core deploy --account MyAwesomeCompany --environment awesome_production --app awesome_app --migrate 'bundle exec rake db:migrate:new_hotness'

Additionally, if you wish to skip migrations for the deployment, you can do that, too:

$ ey-core deploy --account MyAwesomeCompany --environment awesome_production --app awesome_app --no-migrate

Any of the invocations that we've talked about so far will stream the deployment log as it runs. If you'd rather do a fire-and-forget style deployment and check in on it later, you can add the --no-wait flag. If, however, you'd like to see even more information spit out during the deploy, you can add the --verbose flag.

That's about all there is to deployment so long as you consider the application, environment, and account to be required options. You can read more about any of the commands that we've mentioned in this use case by running the following in your terminal:

  • ey-core help accounts
  • ey-core help applications
  • ey-core help deploy
  • ey-core help environments

Client Library Usage

Uses cistern to wrap RESTful resources nicely.

client.users.current  # =>
<Ey::Core::Client::User
  id="0037000000uLmCe",
  name="Josh Lane",
  email="jlane@engineyard.com",
  accounts_url="https://api.engineyard.com/users/0037000000uLmCe/accounts"
>

Authentication

  • Via Token
Ey::Core::Client.new(token: "943662ea7d0fad349eeae9f69adb521d")
  • Via HMAC
Ey::Core::Client.new(
  :auth_id  => "943662ea7d0fad",
  :auth_key => "943662ea7d0fad349eeae9f69adb521d",
  :logger   => Logger.new(STDOUT),
)

Mock

Mock is disabled by default.

Ey::Core::Client.mocking? # => false
Ey::Core::Client.mock!
Ey::Core::Client.mocking? # => true

Reset the mock

Ey::Core::Client.reset!

Testing

By default, specs are run against the core mock. In order to run them against awsm mocked mode instead, run MOCK_CORE=false bundle exec rspec
