Variables

var ErrInvalidLoadBalancerMethod = errors.New("Invalid method, using default")

ErrInvalidLoadBalancerMethod is thrown when the specified load balancing method is invalid.

Types

type Backend

type Backend struct {
	Servers        map[string]Server `json:"servers,omitempty"`
	CircuitBreaker *CircuitBreaker   `json:"circuitBreaker,omitempty"`
	LoadBalancer   *LoadBalancer     `json:"loadBalancer,omitempty"`

}

Backend holds backend configuration.

type CircuitBreaker

type CircuitBreaker struct {
	Expression string `json:"expression,omitempty"`
}

CircuitBreaker holds circuit breaker configuration.

type ConfigMessage

type ConfigMessage struct {
	ProviderName  string
	Configuration *Configuration
}

ConfigMessage hold configuration information exchanged between parts of traefik.

type Configuration

type Configuration struct {
	Backends  map[string]*Backend  `json:"backends,omitempty"`
	Frontends map[string]*Frontend `json:"frontends,omitempty"`
}

Configuration of a provider.

type Constraint

type Constraint struct {
	Key string
	// MustMatch is true if operator is "==" or false if operator is "!="
	MustMatch bool
	// TODO: support regex
	Regex string
}

Constraint hold a parsed constraint expresssion

func NewConstraint

func NewConstraint(exp string) (*Constraint, error)

NewConstraint receive a string and return a *Constraint, after checking syntax and parsing the constraint expression
