Types

type ClientConfig 

type ClientConfig struct {
	// URL gives the location of the Extension server, in standard URL form
	// (`scheme://host:port/path`).
	// Note: Exactly one of `url` or `service` must be specified.
	//
	// The scheme must be "https".
	//
	// The `host` should not refer to a service running in the cluster; use
	// the `service` field instead.
	//
	// A path is optional, and if present may be any string permissible in
	// a URL. If a path is set it will be used as prefix to the hook-specific path.
	//

	// allowed. Fragments ("#...") and query parameters ("?...") are not
	// allowed either.
	//
