Examples with KubernetesClusterStartWorker com.cloud.kubernetes.cluster.actionworkers.KubernetesClusterStartWorker used on opensource projects

Example 1 with KubernetesClusterStartWorker

use of com.cloud.kubernetes.cluster.actionworkers.KubernetesClusterStartWorker in project cloudstack by apache.

the class KubernetesClusterManagerImpl method startKubernetesCluster.

/**
 * Start operation can be performed at two different life stages of Kubernetes cluster. First when a freshly created cluster
 * in which case there are no resources provisioned for the Kubernetes cluster. So during start all the resources
 * are provisioned from scratch. Second kind of start, happens on  Stopped Kubernetes cluster, in which all resources
 * are provisioned (like volumes, nics, networks etc). It just that VM's are not in running state. So just
 * start the VM's (which can possibly implicitly start the network also).
 * @param kubernetesClusterId
 * @param onCreate
 * @return
 * @throws CloudRuntimeException
