Types

type ClientConfig

type ClientConfig struct {
	// allowed qps of the kube client
	KubeClientQPS int
	// allowed burst of the kube client
	KubeClientBurst int
	// config path of the kube client
	ClientKubeConfigPath string
}

ClientConfig defines the configuration of a lower cluster

type VirtualK8S

type VirtualK8S struct {
	// contains filtered or unexported fields
}

VirtualK8S is the key struct to implement the tensile kubernetes

func NewVirtualK8S

func NewVirtualK8S(cfg provider.InitConfig, cc *ClientConfig,
	ignoreLabelsStr string, enableServiceAccount bool, opts *opts.Opts) (*VirtualK8S, error)

NewVirtualK8S reads a kubeconfig file and sets up a client to interact with lower cluster

func (*VirtualK8S) ConfigureNode

func (v *VirtualK8S) ConfigureNode(ctx context.Context, node *corev1.Node)

ConfigureNode enables a provider to configure the node object that will be used for Kubernetes.

func (*VirtualK8S) CreatePod

func (v *VirtualK8S) CreatePod(ctx context.Context, pod *corev1.Pod) error

CreatePod takes a Kubernetes Pod and deploys it within the provider.

func (*VirtualK8S) DeletePod

func (v *VirtualK8S) DeletePod(ctx context.Context, pod *corev1.Pod) error

DeletePod takes a Kubernetes Pod and deletes it from the provider.

func (*VirtualK8S) GetClient

func (v *VirtualK8S) GetClient() kubernetes.Interface

GetClient return the kube client of lower cluster

func (*VirtualK8S) GetContainerLogs

func (v *VirtualK8S) GetContainerLogs(ctx context.Context, namespace string,
	podName string, containerName string, opts api.ContainerLogOpts) (io.ReadCloser, error)

GetContainerLogs retrieves the logs of a container by name from the provider.

func (*VirtualK8S) GetMaster

func (v *VirtualK8S) GetMaster() kubernetes.Interface

GetMaster return the kube client of upper cluster

func (*VirtualK8S) GetNameSpaceLister

func (v *VirtualK8S) GetNameSpaceLister() v1.NamespaceLister

GetNameSpaceLister returns the namespace cache

func (*VirtualK8S) GetPod

func (v *VirtualK8S) GetPod(ctx context.Context, namespace string, name string) (*corev1.Pod, error)

GetPod retrieves a pod by name from the provider (can be cached). The Pod returned is expected to be immutable, and may be accessed concurrently outside of the calling goroutine. Therefore it is recommended to return a version after DeepCopy.

func (*VirtualK8S) GetPodStatus

func (v *VirtualK8S) GetPodStatus(ctx context.Context, namespace string, name string) (*corev1.PodStatus, error)

GetPodStatus retrieves the status of a pod by name from the provider. The PodStatus returned is expected to be immutable, and may be accessed concurrently outside of the calling goroutine. Therefore it is recommended to return a version after DeepCopy.

func (*VirtualK8S) GetPods

func (v *VirtualK8S) GetPods(_ context.Context) ([]*corev1.Pod, error)

GetPods retrieves a list of all pods running on the provider (can be cached). The Pods returned are expected to be immutable, and may be accessed concurrently outside of the calling goroutine. Therefore it is recommended to return a version after DeepCopy.

func (*VirtualK8S) GetStatsSummary

func (v *VirtualK8S) GetStatsSummary(ctx context.Context) (*statsv1alpha1.Summary, error)

GetStatsSummary summaries the cluster metrics which represented by the provider

func (*VirtualK8S) NotifyNodeStatus

func (v *VirtualK8S) NotifyNodeStatus(ctx context.Context, f func(*corev1.Node))

NotifyNodeStatus is used to asynchronously monitor the node. The passed in callback should be called any time there is a change to the node's status. This will generally trigger a call to the Kubernetes API server to update the status.

NotifyNodeStatus should not block callers.

func (*VirtualK8S) NotifyPods

func (v *VirtualK8S) NotifyPods(ctx context.Context, f func(*corev1.Pod))

NotifyPods instructs the notifier to call the passed in function when the pod status changes. It should be called when a pod's status changes.

The provided pointer to a Pod is guaranteed to be used in a read-only fashion. The provided pod's PodStatus should be up to date when this function is called.

NotifyPods will not block callers.

func (*VirtualK8S) Ping

func (v *VirtualK8S) Ping(ctx context.Context) error

Ping tries to connect to client cluster implement node.NodeProvider

func (*VirtualK8S) RunInContainer

func (v *VirtualK8S) RunInContainer(ctx context.Context, namespace string, podName string, containerName string, cmd []string, attach api.AttachIO) error

RunInContainer executes a command in a container in the pod, copying data between in/out/err and the container's stdin/stdout/stderr.

func (*VirtualK8S) UpdatePod

func (v *VirtualK8S) UpdatePod(ctx context.Context, pod *corev1.Pod) error

UpdatePod takes a Kubernetes Pod and updates it within the provider.
