Brig

:speedboat: Brig is a simple way to declaratively provision and run containers for your apps and supporting services.

What?

Brig is basically Foreman and Procfiles on steroids. :muscle:

You specify your environment, processes, and services:

app 'walter'

env :development, {
  # App and Rack
  'HOST' => 'localhost',
  'PORT' => 80,
  'RACK_ENV' => 'development',

  # Puma
  'PUMA_WORKERS' => 1,
  'PUMA_MIN_THREADS' => 1,
  'PUMA_MAX_THREADS' => 1,

  # Sidekiq
  'SIDEKIQ_THREADS' => 1,

  # Redis
  'SILO_REDIS_URL' => '...',
  'SILO_REDIS_CONNECTIONS' => 1,

  # PostgreSQL
  'SILO_DATABASE_URL' => '...',
  'SILO_DATABASE_CONNECTIONS' => 1,

  # Email
  'SMTP_HOST' => '...',
  'SMTP_PORT' => '...',
  'SMTP_USER' => '...',
  'SMTP_PASSWORD' => '...',

  # Storage
  'S3_HOST' => '...',
  'S3_BUCKET' => '...',
  'S3_ACCESS_KEY' => '...',
  'S3_SECRET_ACCESS_KEY' => '...'
}

process :web, 'bundle exec puma -C config/puma.rb', expose: 80
process :worker, 'bundle exec sidekiq -C config/sidekiq.yml'

service :redis, :redis do
  databases 1
end

service :db, :postgres do
  admin 'postgres', 'postgres'
  user 'app', '1ba4e8a57ecaa892a882e37a8475e3c2'
  database 'app', encoding: :utf8 do
    owner 'app'
    grant :all, 'app'
    extensions [:hstore, :plv8]
  end
end

deploy :default, :digital_ocean do
  credentials token: ENV['DIGITALOCEAN_DEPLOY_TOKEN']

  schedule :web do
    cpus min: 4
    memory min: 2.gigabytes

    congruent :worker
    conflicts :cache, :db
  end

  schedule :worker do
    cpus min: 4
    memory min: 2.gigabytes

    congruent :web
    conflicts :cache, :db
  end

  schedule :redis do
    cpus min: 1
    memory min: 1.gigabyte

    conflicts :db
  end

  schedule :db do
    cpus min: 4
    memory min: 4.gigabytes
  end
end

It packages them all up and runs them in containers, and when you're happy you can deploy (and scale) on Amazon AWS, DigitalOcean, and Linode.

Why?

The vast majority of web applications and services don't scale insanely, so simplicity does it. Also, Docker Compose leaves me wanting.

Is it production ready?

I d'unno — roll some dice.
