Types

type Config 

type Config struct {
	// Debug raises the logging emitted from the generated OpenAPI client
	// bindings.
	// +optional
	Debug bool `json:"debug,omitempty"`

	// InsecureSkipTLSVerify skips the validity check for the server's
	// certificate. This will make your HTTPS connections insecure.
	// +optional
	InsecureSkipTLSVerify bool `json:"insecureSkipTLSVerify,omitempty"`

	// Server is the address of the HAProxy dataplane API server. This value
	// should include the scheme, host, port, and API version, ex.:
	// https://hostname:port/v1.
	Server string `json:"server"`

	// ServerName is used to verify the hostname on the returned
	// certificates unless InsecureSkipTLSVerify is given. It is also included
	// in the client's handshake to support virtual hosting unless it is
	// an IP address.
	// Defaults to the host part parsed from Server.
	// +optional
	ServerName string `json:"serverName,omitempty"`

	// Username is the username for basic authentication.
	// Defaults to "client"
	// +optional
	Username string `json:"username,omitempty"`

	// Password is the password for basic authentication.
	// Defaults to "cert"
	// +optional
	Password string `json:"password,omitempty"`

	// Timeout is the amount of time before a client request times out.
	// Values should be parseable by time.ParseDuration.
	// Defaults to 10s.
