Rails Running in a Subdirectory

16 Feb 2020 » rails, nginx, production

I am only familiar with deploying a rails application at the root url. Running in a subdirectory really just messes with everything.

Routes, assets, and javascript really breaks.

Application Side of the House

config.ru

# This file is used by Rack-based servers to start the application.

require_relative 'config/environment'

run Rack::URLMap.new('/commandcenter' => Rails.application)

config/environments/production.rb

Rails.application.configure do
    config.relative_url_root = "/commandcenter"
    host = 'localhost:3000'
    if !ENV['HOST'].nil?
        host = ENV['HOST']
    end
    config.action_controller.asset_host = host
    config.action_mailer.default_url_options = { :host => "https://commandcenter.ourcompose.com" } 
    if !ENV['HOST'].nil?
        config.action_mailer.default_url_options = { :host => ENV['HOST'] }
    end
    config.action_mailer.delivery_method = :smtp
    config.action_mailer.smtp_settings = {
        :address => Rails.application.credentials.smtp[:url],
        :port => Rails.application.credentials.smtp[:port],
        :user_name => Rails.application.credentials.smtp[:user],
        :password => Rails.application.credentials.smtp[:password],
        :authentication => :plain,
        enable_starttls_auto: true
    }
end

NGINX Side

location /commandcenter/ {
    proxy_headers_hash_max_size 512;
    proxy_headers_hash_bucket_size 64;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    add_header Front-End-Https on;
    proxy_pass   http://commandcenter/commandcenter/;
}
