How do I edit StatefulSet in Kubernetes?
Use kubectl edit to modify the size of a Cassandra StatefulSet.
- Run the following command: kubectl edit statefulset cassandra.
- Change the number of replicas to 4, and then save the manifest. The StatefulSet now scales to run with 4 Pods.
- Get the Cassandra StatefulSet to verify your change:
How do I update StatefulSet?
You can stage an update to a StatefulSet by using the partition parameter of the RollingUpdate update strategy. A staged update will keep all of the Pods in the StatefulSet at the current version while allowing mutations to the StatefulSet’s . spec. template .
How do I restart StatefulSet in Kubernetes?
Restart Confluent Platform Cluster
- Find the name of the StatefulSet corresponding to the Confluent Platform cluster you want to restart: kubectl get statefulset –namespace
- Using the StatefulSet name, , from the previous step, roll the cluster:
What is the scope of a rolling update?
Rolling updates allow Deployments’ update to take place with zero downtime by incrementally updating Pods instances with new ones. The new Pods will be scheduled on Nodes with available resources. In the previous module we scaled our application to run multiple instances.
What is the purpose of the statefulset in OpenShift?
StatefulSet represents a set of pods with consistent identities. Identities are defined as: Network: A single stable DNS and hostname. Storage: As many VolumeClaims as requested. The StatefulSet guarantees that a given network identity will always map to the same storage identity.
What does statefulsetcondition mean in the controllerrevision?
The StatefulSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision. Represents the latest available observations of a statefulset’s current state. StatefulSetCondition describes the state of a statefulset at a certain point.
Which is the default value for statefulsetstatus?
RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType. Partition indicates the ordinal at which the StatefulSet should be partitioned. Default value is 0. StatefulSetStatus represents the current state of a StatefulSet.
Which is the specification of a statefulset?
A StatefulSetSpec is the specification of a StatefulSet. StatefulSetStatus represents the current state of a StatefulSet. A StatefulSetSpec is the specification of a StatefulSet. podManagementPolicy controls how pods are created during initial scale up, when replacing pods on nodes, or when scaling down.
