Functions

func NewFakeFirewallsProvider

func NewFakeFirewallsProvider(onXPN bool, fwReadOnly bool) *fakeFirewallsProvider

NewFakeFirewallsProvider creates a fake for firewall rules.

Types

type Firewall

type Firewall interface {
	CreateFirewall(f *compute.Firewall) error
	GetFirewall(name string) (*compute.Firewall, error)
	DeleteFirewall(name string) error
	UpdateFirewall(f *compute.Firewall) error
	GetNodeTags(nodeNames []string) ([]string, error)
	NetworkProjectID() string
	NetworkURL() string

	// OnXPN returns true if the GCE NetworkProjectID != ProjectID.
	OnXPN() bool
}

Firewall interfaces with the GCE firewall api. This interface is a little different from the rest because it dovetails into the same firewall methods used by the TCPLoadBalancer.

type FirewallController

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

FirewallController synchronizes the firewall rule for all ingresses.

func NewFirewallController

func NewFirewallController(
	ctx *context.ControllerContext,
	portRanges []string) *FirewallController

NewFirewallController returns a new firewall controller.

func (*FirewallController) Run

func (fwc *FirewallController) Run()

func (*FirewallController) ToSvcPorts

func (fwc *FirewallController) ToSvcPorts(ings *extensions.IngressList) []utils.ServicePort

ToSvcPorts is a helper method over translator.TranslateIngress to process a list of ingresses. TODO(rramkumar): This is a copy of code in controller.go. Extract this into something shared.

type FirewallRules

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

FirewallRules manages firewall rules.

func (*FirewallRules) GC

func (fr *FirewallRules) GC() error

GC deletes the firewall rule.

func (*FirewallRules) GetFirewall

func (fr *FirewallRules) GetFirewall(name string) (*compute.Firewall, error)

GetFirewall just returns the firewall object corresponding to the given name. TODO: Currently only used in testing. Modify so we don't leak compute objects out of this interface by returning just the (src, ports, error).

func (*FirewallRules) Sync

func (fr *FirewallRules) Sync(nodeNames []string, additionalPorts ...string) error

Sync sync firewall rules with the cloud.

type FirewallXPNError

type FirewallXPNError struct {
	Internal error
	Message  string
}

func (*FirewallXPNError) Error

func (f *FirewallXPNError) Error() string

type SingleFirewallPool

type SingleFirewallPool interface {
	Sync(nodeNames []string, additionalPorts ...string) error
	GC() error
}

SingleFirewallPool syncs the firewall rule for L7 traffic.

func NewFirewallPool

func NewFirewallPool(cloud Firewall, namer *utils.Namer, l7SrcRanges []string, nodePortRanges []string) SingleFirewallPool

NewFirewallPool creates a new firewall rule manager. cloud: the cloud object implementing Firewall. namer: cluster namer.
