IBM Cloud

Follow these instructions to prepare an IBM Cloud cluster for Istio. You can install Istio in IBM Cloud Public or IBM Cloud Private.

IBM Cloud Public

Install the IBM Cloud CLI, the IBM Cloud Kubernetes Service plug-in, and the Kubernetes CLI.
Create a standard Kubernetes cluster. Replace <cluster-name> with the name of the cluster you want to use in the following instructions.
To see available zones, run ibmcloud ks zones. Zones are isolated from each other, which ensures no shared single point of failure. IBM Cloud Kubernetes Service Locations describes available zones and how to specify the zone for your new cluster.
The command below does not contain the --private-vlan value and --public-vlan value options. To see available VLANs, run ibmcloud ks vlans --zone <zone-name>. If you do not have a private and public VLAN yet, they will be automatically created for you. If you already have VLANs, specify them by using the --private-vlan value and --public-vlan value options.
```
$ ibmcloud ks cluster-create --zone <zone-name> --machine-type b3c.4x16 \
  --workers 3 --name <cluster-name>
```
Retrieve your credentials for kubectl.
```
$(ibmcloud ks cluster-config <cluster-name> --export)
```
Make sure to use the kubectl CLI version that matches the Kubernetes version of your cluster.

Configure kubectl to access the IBM Cloud Private Cluster.
