Follow these steps to be accepted as a provider within the Virtual Kubelet repo.

  1. Replicate the life-cycle of a pod for example creation and deletion of a pod and how that maps to your service.
  2. Create a new provider folder with a descriptive name and the necessary code.
  3. When committing your code add a, helm chart, dockerfile and specify a maintainer of the provider.
  4. Within the PR itself add a justification for why the provider should be accepted, as well as customer use cases if applicable.

Some providers are translations of Virtual Kubelet to allow others to adapt their service or applications that are written in other languages.

type InitConfig added in v0.11.0

type InitConfig struct {
	ConfigPath        string
	NodeName          string
	OperatingSystem   string
	InternalIP        string
	DaemonPort        int32
	KubeClusterDomain string
	ResourceManager   *manager.ResourceManager

InitConfig is the config passed to initialize a registered provider.

type InitFunc added in v0.11.0

type InitFunc func(InitConfig) (Provider, error)

type OperatingSystems

type OperatingSystems map[string]bool

func (OperatingSystems) Names

func (o OperatingSystems) Names() []string

type PodMetricsProvider added in v0.6.2

type PodMetricsProvider interface {
	GetStatsSummary(context.Context) (*stats.Summary, error)

PodMetricsProvider is an optional interface that providers can implement to expose pod stats

type Provider added in v0.6.2

type Provider interface {

	// GetContainerLogs retrieves the logs of a container by name from the provider.
	GetContainerLogs(ctx context.Context, namespace, podName, containerName string, opts api.ContainerLogOpts) (io.ReadCloser, error)

	// RunInContainer executes a command in a container in the pod, copying data
	// between in/out/err and the container's stdin/stdout/stderr.
	RunInContainer(ctx context.Context, namespace, podName, containerName string, cmd []string, attach api.AttachIO) error

	// ConfigureNode enables a provider to configure the node object that
	// will be used for Kubernetes.
	ConfigureNode(context.Context, *v1.Node)

Provider contains the methods required to implement a virtual-kubelet provider.

Errors produced by these methods should implement an interface from package in order for the core logic to be able to understand the type of failure.

type Store added in v0.11.0

type Store struct {
	// contains filtered or unexported fields

Store is used for registering/fetching providers

func NewStore added in v0.11.0

func (*Store) Get added in v0.11.0

func (s *Store) Get(name string) InitFunc

Get gets the registered init func for the given name The returned function may be nil if the given name is not registered.

func (*Store) List added in v0.11.0

func (s *Store) List() []string

List lists all the registered providers

func (*Store) Register added in v0.11.0
