Types

type FrontEndService

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

FrontEndService -

func NewFrontEndService

func NewFrontEndService(ctx context.Context, c *feConfig.Config) *FrontEndService

FrontEndService -

func (*FrontEndService) CleanUp

func (fes *FrontEndService) CleanUp()

CleanUp - Basic clean-up of FrontEndService

func (*FrontEndService) Init

func (fes *FrontEndService) Init() error

func (*FrontEndService) Monitor

func (fes *FrontEndService) Monitor(ctx context.Context) error

Monitor - Check bgp prorocols' status by periodically querying birdc. - Log changes in availablity/connectivity. - Reflect external connectivity through NSP to be used by LBs to steer outbound traffic. - Withdraw VIPs in case FE is considered down, in order to not attract traffic through possible available links if any. More like VIPs must be added to BIRD only if the frontend is considered up. (Note: IPv4/IPv6 backplane not separated).

func (*FrontEndService) RemoveVIPRules

func (fes *FrontEndService) RemoveVIPRules() error

RemoveVipRules - Remove all the previously installed VIP src routing rules

func (*FrontEndService) SetNewConfig

func (fes *FrontEndService) SetNewConfig(c interface{}) error

SetNewConfig - Adjust BIRD config on the fly

func (*FrontEndService) Start

func (fes *FrontEndService) Start(ctx context.Context) <-chan error

Start - Start BIRD with the generated config

func (*FrontEndService) Stop

func (fes *FrontEndService) Stop(ctx context.Context)

Stop - Stop BIRD (attempt graceful shutdown)

func (*FrontEndService) VerifyConfig

func (fes *FrontEndService) VerifyConfig(ctx context.Context) error

VerifyConfig - Verify BIRD config file

prerequisite: BIRD must be running so that birdc could talk to it

func (*FrontEndService) WaitStart

func (fes *FrontEndService) WaitStart(ctx context.Context) error

WaitStart - Wait until BIRD started by checking birdc availability
