}

type CompositeQueueType

type CompositeQueueType = string

const (

NOTE: when adding new fields, do not mark them as "omitempty" if it's desirable to read the value from env variables. Config that uses the flytestdlib Config module to generate commandline and load config files. This configuration is the base configuration to start propeller

func GetConfig

func GetConfig() *Config

Extracts the Configuration from the global config module in flytestdlib and returns the corresponding type-casted object. TODO What if the type is incorrect?

func (Config) GetPFlagSet

func (cfg Config) GetPFlagSet(prefix string) *pflag.FlagSet

GetPFlagSet will return strongly types pflags for all fields in Config and its nested types. The format of the flags is json-name.json-sub-name... etc.

type KubeClientConfig

type KubeClientConfig struct {
	// QPS indicates the maximum QPS to the master from this client.
	// If it's zero, the created RESTClient will use DefaultQPS: 5
	QPS float32 `json:"qps" pflag:",Max QPS to the master for requests to KubeAPI. 0 defaults to 5."`
	// Maximum burst for throttle.
	// If it's zero, the created RESTClient will use DefaultBurst: 10.
	Burst int `json:"burst" pflag:",Max burst rate for throttle. 0 defaults to 10"`
	// The maximum length of time to wait before giving up on a server request. A value of zero means no timeout.
	Timeout config.Duration `json:"timeout" pflag:",Max duration allowed for every request to KubeAPI before giving up. 0 implies no timeout."`
}

type LeaderElectionConfig

type LeaderElectionConfig struct {
	// Enable or disable leader election.
	Enabled bool `json:"enabled" pflag:",Enables/Disables leader election."`

	// Determines the name of the configmap that leader election will use for holding the leader lock.
	LockConfigMap types.NamespacedName `json:"lock-config-map" pflag:",ConfigMap namespace/name to use for resource lock."`

	// Duration that non-leader candidates will wait to force acquire leadership. This is measured against time of last
	// observed ack
	LeaseDuration config.Duration `` /* 164-byte string literal not displayed */

	// RenewDeadline is the duration that the acting master will retry refreshing leadership before giving up.
	RenewDeadline config.Duration `json:"renew-deadline" pflag:"\"10s\",Duration that the acting master will retry refreshing leadership before giving up."`

	// RetryPeriod is the duration the LeaderElector clients should wait between tries of actions.
	RetryPeriod config.Duration `json:"retry-period" pflag:"\"2s\",Duration the LeaderElector clients should wait between tries of actions."`
}

Contains leader election configuration.

type WorkqueueConfig

type WorkqueueConfig struct {
	// Refer to https://github.com/kubernetes/client-go/tree/master/util/workqueue
	Type      WorkqueueType   `json:"type" pflag:"\"default\",Type of RateLimiter to use for the WorkQueue"`
	BaseDelay config.Duration `json:"base-delay" pflag:"\"10s\",base backoff delay for failure"`
	MaxDelay  config.Duration `json:"max-delay" pflag:"\"10s\",Max backoff delay for failure"`

	Capacity  int             `json:"capacity" pflag:"100,Bucket capacity as number of items"`
}

prototypical configuration to configure a workqueue. We may want to generalize this in a package like k8sutils

type WorkqueueType

type WorkqueueType = string

const (
	WorkqueueTypeDefault                       WorkqueueType = "default"
	WorkqueueTypeBucketRateLimiter             WorkqueueType = "bucket"
	WorkqueueTypeExponentialFailureRateLimiter WorkqueueType = "expfailure"
	WorkqueueTypeMaxOfRateLimiter              WorkqueueType = "maxof"
)
