DefaultTimeoutOptions default timeout/connection options for the proxy.

Functions

func SecureSocksProxyEnabledOnDS

func SecureSocksProxyEnabledOnDS(jsonData map[string]interface{}) bool

SecureSocksProxyEnabledOnDS checks the datasource json data for `enableSecureSocksProxy` to determine if the secure socks proxy should be enabled on it

Types

type AuthOptions

type AuthOptions struct {
	Username string
	Password string
}

AuthOptions socks5 username and password options. Every datasource can have separate credentials to the proxy.

type Client

type Client interface {
	SecureSocksProxyEnabled() bool
	ConfigureSecureSocksHTTPProxy(transport *http.Transport) error
	NewSecureSocksProxyContextDialer() (proxy.Dialer, error)
}

Client is the main Proxy Client interface.

func New

func New(opts *Options) Client

New creates a new proxy client from a given config.

type ClientCfg

type ClientCfg struct {
	ClientCert    string
	ClientKey     string
	RootCA        string
	ProxyAddress  string
	ServerName    string
	AllowInsecure bool
}

ClientCfg contains the information needed to allow datasource connections to be proxied to a secure socks proxy.

type Options

type Options struct {
	Enabled   bool
	Auth      *AuthOptions
	Timeouts  *TimeoutOptions
	ClientCfg *ClientCfg
}

Options defines per datasource options for creating the proxy dialer.

type TimeoutOptions

type TimeoutOptions struct {
	Timeout   time.Duration
	KeepAlive time.Duration
}

TimeoutOptions timeout/connection options.
