Report releases to Bugsnag using Capistrano.

Use our Capistrano gem to:

  • Report information when you release your app to enable linking to code in your source control provider from the releases dashboard, timeline annotations, and stack traces.


Add the bugsnag-capistrano Ruby gem to your project:

bundle add bugsnag-capistrano

To stop the gem from being loaded automatically outside of your Capistrano environment, you can append require: false to the Gem in your Gemfile:

gem 'bugsnag-capistrano', require: false

Basic configuration

To track releases automatically require bugsnag-capistrano into your Capfile and configure your API key and app version by either:

Setting them in your Capfile:

require 'bugsnag-capistrano'

set :bugsnag_api_key, "your-api-key-here"
set :app_version, "1.3.2"

Or setting the BUGSNAG_API_KEY and BUGSNAG_APP_VERSION environment variables.

Notifying of releases

Release notifications will be sent whenever a release is made via Capistrano in the configured repository, or when manually sent using the bugsnag:release task with the appropriate Capistrano stage (such as production or beta) as your_cap_stage:

cap your_cap_stage bugsnag:release BUGSNAG_API_KEY='your_api_key_here' ...
