Functions

func DoesTargetRefDstPod

func DoesTargetRefDstPod(spec v1alpha3.TrafficTargetSpec, dstPod *corev1.Pod) bool

DoesTargetRefDstPod checks whether the TrafficTarget spec refers to the destination pod's service account

func DoesTargetRefSrcPod

func DoesTargetRefSrcPod(spec v1alpha3.TrafficTargetSpec, srcPod *corev1.Pod) bool

DoesTargetRefSrcPod checks whether the TrafficTarget spec refers to the source pod's service account

func GetChartSource

func GetChartSource(path string) ([]byte, error)

GetChartSource is a helper to convert a filepath to a chart to a base64-encoded, gzipped tarball.

func GetSidecarProxyConfig

func GetSidecarProxyConfig(clientSet kubernetes.Interface, config *rest.Config, namespace string, podName string, localPort uint16, query string) ([]byte, error)

GetSidecarProxyConfig returns the sidecar proxy config of a pod

Types

type EnvConfig

type EnvConfig struct {
	Install EnvConfigInstall `yaml:"install"`
}

EnvConfig represents the environment configuration of FSM

type EnvConfigInstall

type EnvConfigInstall struct {
	Kind         string `yaml:"kind"`
	Distribution string `yaml:"distribution"`
	Namespace    string `yaml:"namespace"`
}

EnvConfigInstall represents the environment configuration of FSM install

type EnvSettings

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

EnvSettings describes all of the cli environment settings

func New

func New() *EnvSettings

New relevant environment variables set and returns EnvSettings

func (*EnvSettings) AddFlags

func (s *EnvSettings) AddFlags(fs *pflag.FlagSet)

AddFlags binds flags to the given flagset.

func (*EnvSettings) Config

func (s *EnvSettings) Config() EnvConfig

Config returns the environment config

func (*EnvSettings) IsManaged

func (s *EnvSettings) IsManaged() bool

IsManaged returns true in a managed FSM environment (ex. managed by a cloud distributor)

func (*EnvSettings) Namespace

func (s *EnvSettings) Namespace() string

Namespace gets the namespace from the configuration

func (*EnvSettings) RESTClientGetter

func (s *EnvSettings) RESTClientGetter() genericclioptions.RESTClientGetter

RESTClientGetter gets the kubeconfig from EnvSettings

func (*EnvSettings) Verbose

func (s *EnvSettings) Verbose() bool

Verbose gets whether verbose output is enabled from the configuration

type Spinner

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

Spinner indicator to fsm install

func (*Spinner) Init

func (s *Spinner) Init(clientSet kubernetes.Interface, fsmNamespace string, vals map[string]interface{})

Init instance of Spinner with the supplied options

func (*Spinner) Run

func (s *Spinner) Run(job func() error) error

Run starts spinner indicator
