Types ¶
type EnvoyConfig ¶
type EnvoyConfig struct {
// contains filtered or unexported fields
}
EnvoyConfig provides a configuration builder that mirrors the upstream Envoy ConfigHelper: a base configuration is used which can be modified by a series of modifiers to create the final configuration.
func NewEnvoyConfig ¶
func NewEnvoyConfig() *EnvoyConfig
NewEnvoyConfig creates a new Envoy config builder, using a sensible default configuration that allows the provided EnvoyHandle to interact with the underlying Envoy instance.
func (*EnvoyConfig) AddCluster ¶
func (e *EnvoyConfig) AddCluster(input string) error
AddCluster adds a cluster to the list of static clusters.
func (*EnvoyConfig) AddHTTPFilter ¶
func (e *EnvoyConfig) AddHTTPFilter(input string) error
AddHTTPFilter adds a HTTP filter in front of the list of HTTP filters for the default listener.
func (*EnvoyConfig) AddRuntimeLayer ¶
func (e *EnvoyConfig) AddRuntimeLayer(input string) error
AddRuntimeLayer adds a single runtime layer to the bootstrap.
func (*EnvoyConfig) Generate ¶
func (e *EnvoyConfig) Generate() (string, error)
Generate generates the final configuration by applying all the config modifiers.
type EnvoyHandle ¶
type EnvoyHandle struct{}
EnvoyHandle is a handle to the Envoy instance under test, providing a startup check and provides utilities for interacting with the instance.
func NewEnvoyHandle ¶
func NewEnvoyHandle() (*EnvoyHandle, error)
NewEnvoyHandle creates a new handle for the Envoy under test after waiting for it to initialize.
func (*EnvoyHandle) EnsureControlPlaneConnectivity ¶
func (e *EnvoyHandle) EnsureControlPlaneConnectivity(prefix string) error
EnsureControlPlaneConnectivity polls the Envoy stats endpoint to ensure that Envoy has an active request against the control plane identified by the provided stat prefix. This is useful in ensuring that Envoy has been able to reconnect to the control plane, even after the exponential backoff that happens as Envoy is unable to connect to the control plane.
func (*EnvoyHandle) MakeSimpleCall ¶
func (e *EnvoyHandle) MakeSimpleCall() (int, error)
MakeSimpleCall issues a basic GET request to the Envoy under test, with the downstream cluster set to test-cluster.
