Virtual Private Cloud See [Limitations](https://cloud.ibm.com/docs/vpc?topic=vpc-limitations) and [Quotas](https://cloud.ibm.com/docs/vpc?topic=vpc-quotas). 
 Worker node flavors Only certain flavors are available for worker node [virtual machines](https://cloud.ibm.com/docs/openshift?topic=openshift-planning_worker_nodesvm). Bare metal machines are not supported. 
 Worker node host access For security, you can't SSH into the worker node compute host. 
 Worker node updates You can't update or reload VPC worker nodes. Instead, you can delete the worker node and rebalance the worker pool with the ibmcloud oc worker replace command. If you replace multiple worker nodes at the same time, they are deleted and replaced concurrently, not one by one. Make sure that you have enough capacity in your cluster to reschedule your workloads before you replace worker nodes. 







 Networking 

Keep in mind that the [service](https://cloud.ibm.com/docs/openshift?topic=openshift-openshift_limitationstech_limits) limitations also apply.



VPC cluster networking limitations

 Category Description 

 App URL length DNS resolution is managed by the cluster's [virtual private endpoint (VPE)](https://cloud.ibm.com/docs/openshift?topic=openshift-vpc-subnetsvpc_basics_vpe), which can resolve URLs up to 130 characters. If you expose apps in your cluster with URLs, such as the Ingress subdomain or Red Hat OpenShift routes, ensure that the URLs are 130 characters or fewer. 
 Network speeds [VPC profile network speeds](https://cloud.ibm.com/docs/vpc?topic=vpc-profiles) refer to the speeds of the worker node interfaces. The maximum speed available to your worker nodes is 25Gbps.

4. Wait for the worker node to finish restarting. If the worker node enters a healthy state, the issue is likely caused by a workload.
5. Schedule one workload at a time onto the worker node to see which workload causes the issue. To schedule the workloads, add the following toleration.

[Migrate](https://cloud.ibm.com/docs/openshift?topic=openshift-costslicenses-on-demand-migrate) your existing worker nodes to take advantage of the new OCP licenses.





 New OCP licenses with reduced pricing, available 9 November 2020 

New OCP licenses include reduced pricing from Red Hat. a Red Hat OpenShift license is billed for every two virtual cores (or one physical cores) of the worker node flavor. Charges vary by the type of worker node that you have, for as long as you have the worker node. For more information, see the [IBM Cloud blog](https://www.ibm.com/cloud/blog/announcements/run-workloads-by-the-hour-with-red-hat-openshift-on-ibm-cloud).



* Virtual machines (VMs): The OCP licenses are billed hourly. For example, you create a worker pool with VMs, test an app for 3 days, and then delete the worker pool. You are billed for only the hours that your worker nodes were deployed.
* Physical machines (bare metal): The OCP licenses are prorated for the first month that you create the worker nodes in, and then billed monthly for the remaining lifecycle of the worker node. For example, you create a cluster with bare metal worker nodes on 15 August and delete the cluster on 14 September. You are charged a prorated monthly cost for the first month of August, but the full monthly cost for September.



When you estimate the cost of a new cluster or worker node, the OCP licenses are included as part of the worker node cost. The OCP licenses are also part of the worker node plan and listed as a sub-item of the worker nodes in your IBM Cloud bill.





 Deprecated: Old OCP licenses for existing worker nodes before 9 November 2020 or deprecated bare metal flavors 

a Red Hat OpenShift license is billed for every four virtual cores (or two physical cores) of the worker node flavor. You are charged for the entire license for each month that you have worker nodes in a deployed state. The monthly charge applies to both virtual and physical worker nodes.

3. Verify that the DNS caching agent pod is running on the worker node.

kubectl get pods -n kube-system -l k8s-app=node-local-dns -o wide

Example output

NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
node-local-dns-pvnjn 1/1 Running 0 1m 10.xxx.xx.xxx 10.xxx.xx.xxx <none> <none>



5. Repeat the previous steps for each worker node to enable DNS caching.







 Disable NodeLocal DNS cache 

You can disable the NodeLocal DNS cache for one or more worker nodes.



1. [Log in to your account. If applicable, target the appropriate resource group. Set the context for your cluster.](https://cloud.ibm.com/docs/containers?topic=containers-access_cluster)
2. Remove the ibm-cloud.kubernetes.io/node-local-dns-enabled label from the worker node. This action terminates the DNS caching agent pod on the worker node.

Run the following command to remove the label from all worker nodes in the cluster.

kubectl label node --all --overwrite "ibm-cloud.kubernetes.io/node-local-dns-enabled-"

Run the following command to remove the label from an individual worker node.

kubectl label node <node_name> "ibm-cloud.kubernetes.io/node-local-dns-enabled-"



1. Verify that the label is removed by checking that the NODE-LOCAL-DNS-ENABLED field is empty.

kubectl get nodes -L "ibm-cloud.kubernetes.io/node-local-dns-enabled"

Example output

NAME STATUS ROLES AGE VERSION NODE-LOCAL-DNS-ENABLED
oc get pv
12. Delete the PVs. Deleting your PVs will make your disks available for other workloads.

oc delete pv <pv-name>
13. Verify that your PV is removed.

oc get pv
