Scale your stateful workloads to your evolving container workload requirements.
Before you begin
To run commands against a user cluster, ensure you have the following resources:
Locate the user cluster name, or ask your Platform Administrator what the cluster name is.
Sign in and generate the kubeconfig file for the user cluster if you don't have one.
Use the kubeconfig path of the user cluster to replace
USER_CLUSTER_KUBECONFIG
in these instructions.
To get the required permissions to scale stateful workloads, ask your Organization IAM Admin to grant you the Namespace Admin role.
Scale a StatefulSet
resource
Leverage the scaling functionality of Kubernetes to appropriately scale the
amount of pods running in your StatefulSet
resource.
Manually scale the pods of a StatefulSet
resource
To manually scale your StatefulSet
resource, run:
kubectl --kubeconfig USER_CLUSTER_KUBECONFIG \
scale statefulset STATEFULSET_NAME \
--replicas NUMBER_OF_REPLICAS
Replace the following:
USER_CLUSTER_KUBECONFIG
: the kubeconfig file for the user cluster.STATEFULSET_NAME
: the name of theStatefulSet
object in which to scale.NUMBER_OF_REPLICAS
: the desired number of replicatedPod
objects in theStatefulSet
object.
Scale the pods by making an in-place update
To scale the pods of a StatefulSet
resource directly in the manifest file,
run:
kubectl --kubeconfig USER_CLUSTER_KUBECONFIG \
patch statefulsets STATEFULSET_NAME \
-p '{"spec":{"replicas":NUMBER_OF_REPLICAS}}'
Replace the following:
USER_CLUSTER_KUBECONFIG
: the kubeconfig file for the user cluster.STATEFULSET_NAME
: the name of theStatefulSet
object in which to scale.NUMBER_OF_REPLICAS
: the desired number of replicatedPod
objects in theStatefulSet
object.
