package deployment

import "k8s.io/kubernetes/pkg/controller/deployment"

Package deployment contains all the logic for handling Kubernetes Deployments. It implements a set of strategies (rolling, recreate) for deploying an application, the means to rollback to previous versions, proportional scaling for mitigating risk, cleanup policy, and other useful features of Deployments.

Constants ¶

const (
	// FullDeploymentResyncPeriod means we'll attempt to recompute the required replicas
	// of all deployments.
	// This recomputation happens based on contents in the local caches.
	FullDeploymentResyncPeriod = 30 * time.Second
	// We must avoid creating new replica set / counting pods until the replica set / pods store has synced.
	// If it hasn't synced, to avoid a hot loop, we'll wait this long between checks.
	StoreSyncedPollPeriod = 100 * time.Millisecond
	// MaxRetries is the number of times a deployment will be retried before it is dropped out of the queue.
	MaxRetries = 5
)

Types ¶

type DeploymentController ¶

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

DeploymentController is responsible for synchronizing Deployment objects stored in the system with actual running replica sets and pods.

func NewDeploymentController ¶

func NewDeploymentController(client clientset.Interface, resyncPeriod controller.ResyncPeriodFunc) *DeploymentController

NewDeploymentController creates a new DeploymentController.

func (*DeploymentController) Run ¶

func (dc *DeploymentController) Run(workers int, stopCh <-chan struct{})

Run begins watching and syncing.
