resources.requests.memory
: Set the minimum amount of worker node memory that the ibm-iks-cluster-autoscaler pod starts with. The default value is 100Mi.

maxNodeProvisionTime
: Set the maximum amount of time in minutes that a worker node can take to begin provisioning before the cluster autoscaler cancels the scale-up request. The default value is 120m.

scaleDownUnneededTime
: Set the amount of time in minutes that a worker node must be unnecessary before it can be scaled down. The default value is 10m.

scaleDownDelayAfterAdd
: Set the amount of time after scale up that scale down evaluation resumes. The default value for scaleDownDelayAfterAdd is 10 minutes. The default value is 10m.

scaleDownDelayAfterDelete
: Set the amount of time after node deletion that scale down evaluation resumes. The default value for scaleDownDelayAfterDelete is the same as the scan-interval which is 1m. The default value is 1m.

scaleDownUtilizationThreshold
: Set the worker node utilization threshold. If the worker node utilization goes under the threshold, the worker node is considered to be scaled down. Worker node utilization is calculated as the sum of the CPU and memory resources that are requested by all pods that run on the worker node, divided by the worker node resource capacity. The default value is 0.5.

scanInterval
: Set how often in minutes that the cluster autoscaler scans for workload usage that triggers scaling up or down. The default value is 1m.

expander
: Specify how the cluster autoscaler determines which worker pool to scale if you have multiple worker pools. The default value is random.

Verify that the VPE gateway for your cluster is created by opening the [Virtual private endpoint gateways for VPC dashboard](https://cloud.ibm.com/vpc-ext/network/endpointGateways) and looking for the VPE gateway in the format iks-<cluster_ID>.
4. If you still can't manage worker nodes after the cluster master is refreshed, replace the worker nodes that you can't access.



1. List all worker nodes in your cluster and note the name of the worker node that you want to replace.

oc get nodes

The name that is returned in this command is the private IP address that is assigned to your worker node. You can find more information about your worker node when you run the ibmcloud oc worker ls --cluster <cluster_name_or_ID> command and look for the worker node with the same Private IP address.
2. Replace the worker node. As part of the replace process, the pods that run on the worker node are drained and rescheduled onto remaining worker nodes in the cluster. The worker node is also cordoned, or marked as unavailable for future pod scheduling. Use the worker node ID that is returned from the ibmcloud oc worker ls --cluster <cluster_name_or_ID> command.

ibmcloud oc worker replace --cluster <cluster_name_or_ID> --worker <worker_node_ID>
3. Verify that the worker node is replaced.

ibmcloud oc worker ls --cluster <cluster_name_or_ID>









 Unable to create or delete worker nodes due to paid account or one time password error

 What’s happening 

You can't manage worker nodes for your cluster, and you receive an error message similar to one of the following examples.

Unable to connect to the IBM Cloud account. Ensure that you have a paid account.

can't authenticate the infrastructure user: Time-based One Time Password authentication is required to log in with this user.

 Why it’s happening 

Your IBM Cloud account uses its own automatically linked infrastructure through a Pay-as-you-Go account.

2. Update the worker node.

ibmcloud oc worker update -c CLUSTER --worker kube-

Example output

The replacement worker node is created in the same zone with the same flavor, but gets new public or private IP addresses. During the replacement, all pods might be rescheduled onto other worker nodes and data is deleted if not stored outside the pod. To avoid downtime, ensure that you have enough worker nodes to handle your workload while the selected worker nodes are being replaced.

3. Wait for the replacement node to be provisioned and then list your worker nodes. Note that this process might take 20 minutes or more.
