Constants

const (
	// MaxDisruptedPodSize is the max size of PodDisruptionBudgetStatus.DisruptedPods. API server eviction
	// subresource handler will refuse to evict pods covered by the corresponding PDB
	// if the size of the map exceeds this value. It means a large number of
	// evictions have been approved by the API server but not noticed by the PDB controller yet.
	// This situation should self-correct because the PDB controller removes
	// entries from the map automatically after the PDB DeletionTimeout regardless.
	MaxDisruptedPodSize = 2000
)

Variables

var EvictionsRetry = wait.Backoff{
	Steps:    20,
	Duration: 500 * time.Millisecond,
	Factor:   1.0,
	Jitter:   0.1,
}

EvictionsRetry is the retry for a conflict where multiple clients are making changes to the same resource.

Types

type BindingREST

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

BindingREST implements the REST endpoint for binding pods to nodes when etcd is in use.

func (*BindingREST) Create

func (r *BindingREST) Create(ctx api.Context, obj runtime.Object) (out runtime.Object, err error)

Create ensures a pod is bound to a specific host.

func (*BindingREST) New

func (r *BindingREST) New() runtime.Object

New creates a new binding resource

type EvictionREST

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

EvictionREST implements the REST endpoint for evicting pods from nodes when etcd is in use.

func (*EvictionREST) Create

func (r *EvictionREST) Create(ctx api.Context, obj runtime.Object) (runtime.Object, error)

Create attempts to create a new eviction. That is, it tries to evict a pod.

func (*EvictionREST) New

func (r *EvictionREST) New() runtime.Object

New creates a new eviction resource

type PodStorage

type PodStorage struct {
	Pod         *REST
	Binding     *BindingREST
	Eviction    *EvictionREST
	Status      *StatusREST
	Log         *podrest.LogREST
	Proxy       *podrest.ProxyREST
	Exec        *podrest.ExecREST
	Attach      *podrest.AttachREST
	PortForward *podrest.PortForwardREST
}

PodStorage includes storage for pods and all sub resources

func NewStorage

func NewStorage(opts generic.RESTOptions, k client.ConnectionInfoGetter, proxyTransport http.RoundTripper, podDisruptionBudgetClient policyclient.PodDisruptionBudgetsGetter) PodStorage

NewStorage returns a RESTStorage object that will work against pods.

type REST

type REST struct {
	*registry.Store
	// contains filtered or unexported fields
}

REST implements a RESTStorage for pods against etcd

func (*REST) ResourceLocation

func (r *REST) ResourceLocation(ctx api.Context, name string) (*url.URL, http.RoundTripper, error)

ResourceLocation returns a pods location from its HostIP

type StatusREST

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

StatusREST implements the REST endpoint for changing the status of a pod.

func (*StatusREST) Get

func (r *StatusREST) Get(ctx api.Context, name string) (runtime.Object, error)

Get retrieves the object from the storage. It is required to support Patch.

func (*StatusREST) New

func (r *StatusREST) New() runtime.Object

New creates a new pod resource

func (*StatusREST) Update

func (r *StatusREST) Update(ctx api.Context, name string, objInfo rest.UpdatedObjectInfo) (runtime.Object, bool, error)

Update alters the status subset of an object.
