Functions

func GetSessionAWS

func GetSessionAWS() (*session.Session, error)

func GetValidLambdaRegions

func GetValidLambdaRegions() []string

func NewSSHManager

func NewSSHManager() ([]byte, error)

NewSSHManager generates an ssh key and adds to authorized_keys so Lambda can connect to the host

func SetupLambdaInfrastructure

func SetupLambdaInfrastructure(lambdaIamRole string) error

SetupLambdaInfrastructure sets up IAM role needed to run awslambdaproxy

Types

type Config

type Config struct {
	// LambdaName is a name of Lambda function
	LambdaName string
	// LambdaIamRoleName is a name of Lambda function IAM role
	LambdaIamRoleName string
	// LambdaRegions is all regions to execute Lambda functions in
	LambdaRegions []string
	// LambdaMemory is the size of memory to assign Lambda function
	LambdaMemory int
	// LambdaExecutionFrequency is the frequency at which to execute Lambda functions
	LambdaExecutionFrequency time.Duration
	// ProxyListeners defines all listeners, protocol, and auth information
	// in format like this [scheme://][user:pass@host]:port.
	// see https://github.com/ginuerzh/gost/blob/master/README_en.md#getting-started
	ProxyListeners []string
	// ProxyDebug is whether debug logging should be shown for proxy traffic
	// note this will log all visited domains
	ProxyDebug bool
	// ReverseTunnelSSHUser is the ssh user to use for the lambda reverse ssh tunnel
	ReverseTunnelSSHUser string
	// ReverseTunnelSSHPort is the ssh port to use for the lambda reverse ssh tunnel
	ReverseTunnelSSHPort string
	// Debug enables general debug logging
	Debug bool
	// Bypass is a comma separated list of ips/domains to bypass proxy
	Bypass string
}

Config is used to define the configuration for Server

type LocalProxy

type LocalProxy struct {
	// contains filtered or unexported fields
}

LocalProxy is proxy listener and where to forward

func NewLocalProxy

func NewLocalProxy(listeners []string, debugProxy bool, bypass string) (*LocalProxy, error)

NewLocalProxy starts a local proxy that will forward to proxy running in Lambda

type Server

type Server struct {
	// contains filtered or unexported fields
}

Server is the long running server component of awslambdaproxy

func New

func New(config Config) (*Server, error)

func (*Server) Run

func (s *Server) Run()
