StatefulSet

Quick Start

R.stateful_set :database do
  container do
    image 'postgres:alpine'

    expose_port 5432

    environment do
      add POSTGRES_USER: 'postgres', POSTGRES_PASSWORD: 'secretpassword'
    end

    mount_volume :data, '/var/lib/postgresql/data', sub_path: 'data'
  end

  volume_claim :data do
    access_mode :ReadWriteOnce
    storage_request '8Gi'
    storage_class_name 'ssd'
  end
end

StatefulSet is one of the Pod Template Owners, so all methods, like pod_template and container are available.
