Panter Rails Deploy

This gem sets up everything you need to deploy your application on the Panter Rails hosting:

How to use

Add to your Gemfile (globally, not in a group):
```
gem 'panter-rails-deploy'
```
Note: Also remove these gems if already present:
- unicorn, unicorn-rails
- dotenv, dotenv-rails
- capistrano, capistrano-ext, capistrano-rails, capistrano-bundler, capistrano-rbenv
- therubyracer
- mini_racer
Capify your project (bundle exec is required here, unless you use rbenv-binstubs):
```
bundle exec cap install
```
Load the gem in your Capfile with one of these lines:

For a standard Rails project with asset compilation:
```
require 'panter-rails-deploy'
```
For a Rails project that doesn't use asset compilation:
```
require 'panter-rails-deploy/without-assets'
```
For other Rack applications:
```
require 'panter-rails-deploy/without-rails'
```
Set :application and :repo_url in config/deploy.rb (note that in previous Capistrano versions it was called :repository instead)

Set up your stages in config/deploy folder (e.g. config/deploy/production.rb):

server 'my-server.example.com', roles: %w[ web app db ]
set :branch, 'master'
set :rails_env, 'staging' # 'production' by default for all stages

Using dotenv is the recommended approach to store sensitive configuration in the environment instead of code repositories.

Add a file on your servers in /home/app/app/shared/.env with your keys:
```
RAILS_SECRET_KEY_BASE: 89d20f0...
```
- You can add any other key-value pairs, they'll simply be injected into ENV
- You can use rake secret / rails secret (Rails 5) to generate a new secure key
- Rails uses SECRET_KEY_BASE by default, but adding a RAILS_ prefix is recommended since dotenv itself is framework-agnostic
If you need keys in development as well, add .env locally and add it to .gitignore
Replace your keys in config/secrets.yml and other places with references to ENV:
```
production:
secret_key_base: <%= ENV["RAILS_SECRET_KEY_BASE"] %>
```
Update config/deploy.rb to symlink the .env file during deploy:
```
append :linked_files, '.env'
```
