Install highly available KubeSphere on HUAWEI CLOUD

As the scenarios of multi-cloud and multi-cluster become more and more abundant, the demand for deploying KubeSphere in the environments of various cloud vendors has also increased. Because cloud resource usage rules and menu navigation bars of various cloud vendors are different, users will spend a lot of time troubleshooting. In order to reduce the error rate of the deployment process, this tutorial uses the HUAWEI CLOUD platform to deploy a set of highly available KubeSphere, hoping to help you improve your deployment experience.

1. Pre-deployment preparation

The resources of the required environment can meet the following conditions:

Huawei Cloud Products	quantity	use	Remark
ECS cloud server	6	master、node
VPC	1	Availability zone
ELB	2	Load balancing
Security group	1	Import and export control
Public IP	7	Internet access

2. Cloud platform resource initialization

1. Create a VPC

Go to HUAWEI CLOUD Control, select "Virtual Private Cloud" in the list on the left, and select "Create Virtual Private Cloud" to create a VPC. The configuration is as shown in the figure below:

2. Create a security group

Create a security group, set the inbound rules and associated examples as follows:

3. Create an instance

In the network configuration, the network selects the VPC and subnet created in the first step. In the security group, select the security group created in the previous step.

4. Create a load balancer (create two inside and outside)

Intranet ELB:

Extranet ELB:

If the cluster needs to be configured with public network access, you need to configure a public network IP for the external network load balancer. Add a back-end listener for all nodes. The listening port is 80 (the test uses port 30880. Here, port 80 also needs to be in the security group. open).

The following configuration file config.yaml needs to configure the address (VIP) assigned by the intranet SLB created earlier

 controlPlaneEndpoint:
         domain: lb.kubesphere.local
         address: "192.168.0.205"
         port: "6443"

Deploy the KubeSphere platform

1. Download KK

$ curl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -

2. Add execution permissions

$ chmod +x kk

3. Use kubekey to deploy

$ ./kk create config --with-kubesphere v3.1.1 --with-kubernetes v1.17.9 -f master-HA.yaml

4. Cluster configuration adjustment
