Functions ¶
func CloudVMPublicAddress ¶
CloudVMPublicAddress returns the public IP address of the Cloud VM instance it is run from, or nil if run from anywhere else. The returned address is the public address of a 1:1 NAT tunnel to this host.
func ConfigureGlobalLoggerFromFlags ¶
func ConfigureGlobalLoggerFromFlags() error
ConfigureGlobalLoggerFromFlags configures the global logger from command line flags. Should be called immediately after ParseFlags.
func HasPublicIP ¶
HasPublicIP returns true if the host has at least one public IP address.
func InitCloudVM ¶
func InitCloudVM() error
InitCloudVM initializes the CloudVM metadata.
If EnvExpectGoogleComputeEngine is set, this function returns after the initialization is done. Otherwise, the initialization is done asynchronously and future calls to CloudVMPublicAddress() will block until the initialization is complete.
Returns an error if EnvExpectGoogleComputeEngine is set and the metadata server is inaccessible.
func NewAddressChooser ¶
func NewAddressChooser(logger logging.Logger) rpc.AddressChooser
NewAddressChooser will return the public IP of process if the process is being hosted by a cloud service provider (e.g. Google Compute Engine, Amazon EC2), and if not will be the same as IPAddressChooser.
func ParseFlags ¶
ParseFlags parses all registered flags taking into account overrides from other configuration and environment variables. It must be called by the profile and flags.RuntimeFlags() must be passed to the runtime initialization function. The profile can use or modify the flags as it pleases.
func ParseFlagsAndConfigureGlobalLogger ¶
ParseFlagsAndConfigurGlobalLogger calls ParseFlags and then ConfigureGlobalLoggerFromFlags.
Types ¶
type IPAddressChooser ¶
type IPAddressChooser struct{}
IPAddressChooser returns the preferred IP address, which is, a public IPv4 address, then any non-loopback IPv4, then a public IPv6 address and finally any non-loopback/link-local IPv6
func (IPAddressChooser) ChooseAddresses ¶
