Functions ¶
func MutatePVC ¶
func MutatePVC(ctx context.Context, review *kwhmodel.AdmissionReview, obj metav1.Object) (*kwhmutating.MutatorResult, error)
func MutatePod ¶
func MutatePod(ctx context.Context, review *kwhmodel.AdmissionReview, obj metav1.Object) (*kwhmutating.MutatorResult, error)
MutatePod is used to modify Pods requests before they arrive to the Virtual Kubelet Framework. This is because the frameworks drops pods whose containers involve "valueFrom = .status.podIP" semantics. Ref: https://github.com/Azure/AKS/issues/2427#issuecomment-1010354262
func NodeConditions ¶
func NodeConditions(_ context.Context) []corev1.NodeCondition
NodeConditions creates a slice of node conditions representing a kubelet in perfect health. These four conditions are the ones which virtual-kubelet sets as Unknown when a Ping fails.
Types ¶
type InitConfig ¶
type InitConfig struct {
InternalIP string
DaemonPort int32
BuildVersion string
FSPollingInterval time.Duration
RestConfig *rest.Config
}
InitConfig is the config passed to initialize a registered provider.
type VirtualK8S ¶
type VirtualK8S struct {
InitConfig
Logger logr.Logger
// contains filtered or unexported fields
}
VirtualK8S implements the virtual-kubelet provider interface and stores pods in memory.
func NewVirtualK8S ¶
func NewVirtualK8S(config InitConfig) (*VirtualK8S, error)
NewVirtualK8S reads a kubeconfig file and sets up a client to interact with Slurm cluster. It is designed to restore missing state after a restart.
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) DeletePod ¶
DeletePod takes a Kubernetes Pod and deletes it from the provider. Once a pod is deleted, the provider is expected to call the NotifyPods callback with a terminal pod status where all the containers are in a terminal state, as well as the pod. DeletePod may be called multiple times for the same pod.
func (*VirtualK8S) GetContainerLogs ¶
func (v *VirtualK8S) GetContainerLogs(ctx context.Context, namespace, podName, containerName string, opts vkapi.ContainerLogOpts) (io.ReadCloser, error)
GetContainerLogs retrieves the logs of a container by name from the provider.
func (*VirtualK8S) GetPod ¶
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 the calling goroutine. Therefore, it is recommended to return a version after DeepCopy.
func (*VirtualK8S) GetPodStatus ¶
func (v *VirtualK8S) GetPodStatus(ctx context.Context, namespace, 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 the calling goroutine. Therefore, it is recommended to return a version after DeepCopy.
func (*VirtualK8S) GetPods ¶
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 the calling goroutine. Therefore, it is recommended to return a version after DeepCopy.
func (*VirtualK8S) GetStatsSummary ¶
func (v *VirtualK8S) GetStatsSummary(context.Context) (*statsv1alpha1.Summary, error)
func (*VirtualK8S) NewVirtualNode ¶
func (v *VirtualK8S) NewVirtualNode(ctx context.Context, nodename string, taint *corev1.Taint) *corev1.Node
NewVirtualNode builds a kubernetes node object from a provider This is a temporary solution until node stuff actually split off from the provider interface itself.
func (*VirtualK8S) NodeAddresses ¶
func (v *VirtualK8S) NodeAddresses(_ context.Context) []corev1.NodeAddress
func (*VirtualK8S) NodeDaemonEndpoints ¶
func (v *VirtualK8S) NodeDaemonEndpoints(_ context.Context) corev1.NodeDaemonEndpoints
func (*VirtualK8S) NodeSystemInfo ¶
func (v *VirtualK8S) NodeSystemInfo(_ context.Context) corev1.NodeSystemInfo
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 must not block the caller since it is only used to register the callback. The callback passed into `NotifyPods` may block when called.
func (*VirtualK8S) RunInContainer ¶
func (v *VirtualK8S) RunInContainer(ctx context.Context, namespace, podName, containerName string, cmd []string, attach vkapi.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.
