Overview

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

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(dInformer informers.DeploymentInformer, rsInformer informers.ReplicaSetInformer, podInformer informers.PodInformer, client clientset.Interface) *DeploymentController

NewDeploymentController creates a new DeploymentController.

func (*DeploymentController) Run

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

Run begins watching and syncing.
