Librato Rake Deploytrack

Rake tasks to keep track of your deploys in Librato Metrics, using the annotations streams!

Installation

Librato Rake Deploytrack is a collection of raketasks. So you should be able to include them in every application utilizing rake.

Add this gem to your Gemfile

gem 'librato-rake-deploytrack'

Installation (Rails 4.x)

Nothing \o/

Librato Rake Deploytrack hooks automatically into rake.

Installation w/o Rails

To use Librato Rake Deploytrack without Rails simply require it in your Rakefile

require 'librato-rake-deploytrack'

Configuration

All configuration is done via environment variables. There are four thing you can tweak

• LIBRATO_USER - REQUIRED
• LIBRATO_TOKEN - REQUIRED
• LIBRATO_SOURCE - this defaults to production
• LIBRATO_DEPLOY_FILE - this defaults to librato-rake-deploytrack-deploy-id - the file which is used to keep track of your state during the deploy

LIBRATO_USER, LIBRATO_TOKEN and LIBRATO_SOURCE are also used within [librato-rails](https://github.com/librato/librato-rails so if you use that gem and configure it also with environment variables you are good to go right away.

Usage

Librato Rake Deploytrack should be pretty simple to integrate into your deploy process. You just have to wrap your actual deploy call with the two rake tasks. Here is a small example

#scripts/my_deploy.sh
rake librato:deploy:start['Deploy v47', 'This deploy fixes #63 #67 #74 and also improves performance']
git push heroku master
rake librato:deploy:end

As you see the librato:deploy:start takes two arguments:

• title The title of an annotation is a string and may contain spaces. The title should be a short, high-level summary of the annotation e.g. v45 Deployment. The title is a required parameter to create an annotation.
• description The description contains extra meta-data about a particular annotation. The description should contain specifics on the individual annotation e.g. Deployed 9b562b2: shipped new feature foo!

Usage in Travis CI

You have a before_deploy and a after_deploy run level you can use like this

before_deploy:
  - rake librato:deploy:start["deploy $TRAVIS_REPO_SLUG","Travis deployed https://github.com/<your-org>/<your-repo>/compare/$TRAVIS_COMMIT_RANGE"]
after_deploy:
  - rake librato:deploy:end

Using this gem in Travis CI deployment has a few pitfalls. First of all it requires your user and token in the environment. You can solve the non-that-secret user with a global environment variable but to keep your token secret it's highly recommended to encrypt it! Here is a example how a environment config could look like.

env:
  global:
    - LIBRATO_USER=user@example.com
    - secure: "SJXa[...just...a...bunch...of...chars...]e5uofDKs="

this one might depend on the deployment provider you are using. Travis usually cleans up your repo before deploying, that would result in the state-keeping-file be deleted. To avoid this you should skip the cleaning. With heroku you can do it with the skip_cleanup: true parameter.
