type Config ¶
type Config struct {
// DevMode controls if we are in a development mode which
// avoids persistent storage.
DevMode bool
// StateDir is where we store our state
StateDir string
// AllocDir is where we store data for allocations
AllocDir string
// LogOutput is the destination for logs
LogOutput io.Writer
// Region is the clients region
Region string
// Network interface to be used in network fingerprinting
NetworkInterface string
// Network speed is the default speed of network interfaces if they can not
// be determined dynamically.
NetworkSpeed int
// CpuCompute is the default total CPU compute if they can not be determined
// dynamically. It should be given as Cores * MHz (2 Cores * 2 Ghz = 4000)
CpuCompute int
// MaxKillTimeout allows capping the user-specifiable KillTimeout. If the
// task's KillTimeout is greater than the MaxKillTimeout, MaxKillTimeout is
// used.
MaxKillTimeout time.Duration
// Servers is a list of known server addresses. These are as "host:port"
Servers []string
// RPCHandler can be provided to avoid network traffic if the
// server is running locally.
RPCHandler RPCHandler
// Node provides the base node
Node *structs.Node
// ClientMaxPort is the upper range of the ports that the client uses for
// communicating with plugin subsystems over loopback
ClientMaxPort uint

}
Config is used to parameterize and configure the behavior of the client
func DefaultConfig ¶ added in v0.4.0
func DefaultConfig() *Config
DefaultConfig returns the default configuration
func (*Config) ReadBoolDefault ¶ added in v0.2.0
ReadBoolDefault tries to parse the specified option as a boolean. If there is an error in parsing, the default option is returned.
func (*Config) ReadDefault ¶
ReadDefault returns the specified configuration value, or the specified default value if none is set.
func (*Config) ReadDuration ¶ added in v0.5.5
ReadDuration parses the specified option as a duration.
func (*Config) ReadDurationDefault ¶ added in v0.5.5
ReadDurationDefault tries to parse the specified option as a duration. If there is an error in parsing, the default option is returned.
func (*Config) ReadIntDefault ¶ added in v0.5.5
ReadIntDefault tries to parse the specified option as a int. If there is an error in parsing, the default option is returned.
func (*Config) ReadStringListToMap ¶ added in v0.2.1
ReadStringListToMap tries to parse the specified option as a comma separated list. If there is an error in parsing, an empty list is returned.
func (*Config) ReadStringListToMapDefault ¶ added in v0.3.2
ReadStringListToMap tries to parse the specified option as a comma separated list. If there is an error in parsing, an empty list is returned.
func (*Config) TLSConfiguration ¶ added in v0.5.0
TLSConfig returns a TLSUtil Config based on the client configuration
type RPCHandler ¶
RPCHandler can be provided to the Client if there is a local server to avoid going over the network. If not provided, the Client will maintain a connection pool to the servers
