def initialize(connection, hash={})
  unless connection.is_a?(Docker::Connection)
    raise ArgumentError, "Expected a Docker::Connection, got: #{connection}."
  end
  normalize_hash(hash)
  @connection, @info, @id = connection, hash, hash['id']
  raise ArgumentError, "Must have id, got: #{hash}" unless @id
end

#normalize_hash(hash) ⇒ Object

The docker-api will some time return “ID” other times it will return “Id” and other times it will return “id”. This method normalize it to “id” The volumes endpoint returns Name instead of ID, added in the normalize function
