Capistrano 3 Env Management

Small Capistrano utility that allows easy management of app-specific environment variables (currently supporting dotenv only)

Add the gem to your Gemfile

gem 'capistrano3-env', '~> 0.1.0'

Run bundle to update your Gemfile.lock Add the following to your Capfile:

require 'capistrano/env'

Rake (which is used by Capistrano) has a not so pratical way of specifying task arguments. To alleviate that issue, a small custom executable was made:

bundle exec cap-env [stage] [operation] [KEY] [VALUE]

The possible use cases are the following:

cap-env production get               # shows the current env file for
production
cap-env production set APP_ID 123456 # sets KEY=value
cap-env production get APP_ID        # shows the current value of KEY
cap-env production delete APP_ID     # deletes the given KEY

Alternatively, you can use the underlying Capistrano tasks directly with cap production TASK, where TASK is one of the following:

env:get            # shows the current env file
env:get[KEY]       # KEY # shows the current value of KEY from the env file
env:set[KEY,value] # sets KEY=value in the env file
env:delete[KEY]    # deletes the given KEY

The following configurations are available to you in config/deploy.rb (default values are shown here, no need to set them)

set :config_backend, :dotenv # currently this is the only supported backend
set :config_file,    '.env'  # you might want to use .env.production instead
