Functions

func AreAllPodsRunning

func AreAllPodsRunning(podPrefix, namespace string) (bool, error)

AreAllPodsRunning will return true if all pods are in a Running State

func WaitOnReady

func WaitOnReady(podPrefix, namespace string, sleep, duration time.Duration) (bool, error)

WaitOnReady will block until all nodes are in ready state

Types

type Container

type Container struct {
	Image string `json:"image"`
	Ports []Port `json:"ports"`
}

Container holds information like image and ports

type List

type List struct {
	Pods []Pod `json:"items"`
}

List is a container that holds all pods returned from doing a kubectl get pods

func GetAll

func GetAll(namespace string) (*List, error)

GetAll will return all pods in a given namespace

type Metadata

type Metadata struct {
	CreatedAt time.Time         `json:"creationTimestamp"`
	Labels    map[string]string `json:"labels"`
	Name      string            `json:"name"`
	Namespace string            `json:"namespace"`
}

Metadata holds information like name, createdat, labels, and namespace

type Pod

type Pod struct {
	Metadata Metadata `json:"metadata"`
	Spec     Spec     `json:"spec"`
	Status   Status   `json:"status"`
}

Pod is used to parse data from kubectl get pods

func Get

func Get(podName, namespace string) (*Pod, error)

Get will return a pod with a given name and namespace

func GetAllByPrefix

func GetAllByPrefix(prefix, namespace string) ([]Pod, error)

GetAllByPrefix will return all pods in a given namespace that match a prefix

func (*Pod) CheckLinuxOutboundConnection

func (p *Pod) CheckLinuxOutboundConnection(sleep, duration time.Duration) (bool, error)

CheckLinuxOutboundConnection will keep retrying the check if an error is received until the timeout occurs or it passes. This helps us when DNS may not be available for some time after a pod starts.

func (*Pod) CheckWindowsOutboundConnection

func (p *Pod) CheckWindowsOutboundConnection(sleep, duration time.Duration) (bool, error)

CheckWindowsOutboundConnection will keep retrying the check if an error is received until the timeout occurs or it passes. This helps us when DNS may not be available for some time after a pod starts.

func (*Pod) Exec

func (p *Pod) Exec(cmd ...string) ([]byte, error)

Exec will execute the given command in the pod

func (*Pod) ValidateHostPort

func (p *Pod) ValidateHostPort(check string, attempts int, sleep time.Duration, master, sshKeyPath string) bool

ValidateHostPort will attempt to run curl against the POD's hostIP and hostPort

type Port

type Port struct {
	ContainerPort int `json:"containerPort"`
	HostPort      int `json:"hostPort"`
}

Port represents a container port definition

type Spec

type Spec struct {
	Containers []Container `json:"containers"`
}

Spec holds information like containers

type Status

type Status struct {
	HostIP    string    `json:"hostIP"`
	Phase     string    `json:"phase"`
	PodIP     string    `json:"podIP"`
	StartTime time.Time `json:"startTime"`
}

Status holds information like hostIP and phase
