Follow these instructions to prepare a cluster for Istio using the Huawei Cloud Container Engine. You can deploy a Kubernetes cluster to Huawei Cloud quickly and easily in the Cloud Container Engine Console, which fully supports Istio.

Following the Huawei Cloud Instructions to prepare a cluster before manually installing Istio, proceed as follows:

Log in to the CCE console. Choose Dashboard > Buy Cluster to open the Buy Hybrid Cluster page. An alternative way to open that page is to choose Resource Management > Clusters in the navigation pane and click Buy next to Hybrid Cluster.
On the Configure Cluster page, configure cluster parameters. In this example, a majority of parameters retain default values. After the cluster configuration is complete, click Next: Create Node to go to the node creation page.
Istio release has some requirements for the Kubernetes version, select the version according to Istio’s support policy.
The image below shows the GUI where you create and configure the cluster:
Configure Cluster
On the node creation page, configure the following parameters
Istio adds some additional resource consumption, from our experience, reserve at least 4 vCPU and 8 GB memory to begin playing.
The image below shows the GUI where you create and configure the node:
Configure Node
Configure kubectl
Now you can install Istio on CCE cluster according to install guide.
Configure ELB to expose Istio ingress gateway if needed.
- Create Elastic Load Balancer
- Bind the ELB instance to istio-ingressgateway service
  Set the ELB instance ID and loadBalancerIP to istio-ingressgateway.
