The formats inside omskstar.ru are # declare ConfigMap as a resource resources: omskstar.ru # declare ConfigMap from a ConfigMapGenerator. If you try a rolling update on a DaemonSet that was created from Kubernetes version or before, a rollout will be triggered when you first change the DaemonSet update strategy to RollingUpdate, no matter if DaemonSet template is modified or not.
If the DaemonSet template is not changed, all existing DaemonSet pods will be restarted (deleted.

Managing Deployments using Kubernetes is an interesting lab which will give you an insight into how to create deployments from Kubernetes manifest (yaml) file, update and scale deployments. You will also be practicing with kubectl (command line interface for running commands against Kubernetes clusters).
Rolling updates allow Deployments' update to take place with zero downtime by incrementally updating Pods instances with new ones. Rolling Update on a Deployment. This Rolling update created a new ReplicaSet, started spinning up pods in that new ReplicaSet and as the new pods were created, it terminated the pods in the old ReplicaSet.
