SetUpCiliumInIpvlanMode starts cilium-agent in the ipvlan mode

func (*SSHMeta) SetUpCiliumWithOptions 

func (s *SSHMeta) SetUpCiliumWithOptions(template string) error

SetUpCiliumWithOptions sets up Cilium as a systemd service with a given set of options. It returns an error if any of the operations needed to start Cilium fail.

func (*SSHMeta) SetUpCiliumWithSockops 

func (s *SSHMeta) SetUpCiliumWithSockops() error

func (*SSHMeta) String 

func (s *SSHMeta) String() string

func (*SSHMeta) ValidateNoErrorsInLogs 

func (s *SSHMeta) ValidateNoErrorsInLogs(duration time.Duration)

ValidateNoErrorsInLogs checks in cilium logs since the given duration (By default `CurrentGinkgoTestDescription().Duration`) do not contain `panic`, `deadlocks` or `segmentation faults` messages . In case of any of these messages, it'll mark the test as failed.

func (*SSHMeta) WaitEndpointRegenerated 

func (s *SSHMeta) WaitEndpointRegenerated(id string) bool

WaitEndpointRegenerated attempts up until MaxRetries are exceeded for the endpoint with the specified ID to be in "ready" state. Returns false if no such endpoint corresponds to the given id or if MaxRetries are exceeded.

func (*SSHMeta) WaitEndpointsDeleted 

func (s *SSHMeta) WaitEndpointsDeleted() bool

WaitEndpointsDeleted waits up until timeout reached for all endpoints to be deleted. Returns true if all endpoints have been deleted before HelperTimeout is exceeded, false otherwise.

func (*SSHMeta) WaitEndpointsReady 

func (s *SSHMeta) WaitEndpointsReady() bool

WaitEndpointsReady waits up until timeout reached for all endpoints to not be in any regenerating or waiting-for-identity state. Returns true if all endpoints regenerate before HelperTimeout is exceeded, false otherwise.

func (*SSHMeta) WaitUntilReady 

func (s *SSHMeta) WaitUntilReady(timeout time.Duration) error

WaitUntilReady waits until the output of `cilium status` returns with code zero. Returns an error if the output of `cilium status` returns a nonzero return code after the specified timeout duration has elapsed.

type SSHMetaError
