Public Class Methods

credential() click to toggle source

This is the named credential from amongst the configuration file being used or :default

@note This can be set using the FOG_CREDENTIAL environment variable

@return [Symbol] The credential to use in Fog

# File lib/fog/core/credentials.rb, line 40
def self.credential
  @credential ||= (ENV["FOG_CREDENTIAL"] && ENV["FOG_CREDENTIAL"].to_sym) || :default
end

credential=(new_credential) click to toggle source

Assign a new credential to use from configuration file

@param [String, Symbol] new_credential name of new credential to use @return [Symbol] name of the new credential

# File lib/fog/core/credentials.rb, line 30
def self.credential=(new_credential)
  @credentials = nil

end

credentials_path() click to toggle source

This returns the path to the configuration file being used globally to look for sets of credentials

@note This can be set using the FOG_RC environment variable or defaults to +$HOME/.fog+
