Setup Kubernetes (version 1.18) cluster on AWS EC2

问题

I am trying to setup Kubernetes on AWS EC2 there are writeups from this website which is wonderful

https://itnext.io/kubernetes-part-2-a-cluster-set-up-on-aws-with-aws-cloud-provider-and-aws-loadbalancer-f02c3509f2c2

I used the following config file for "kubeadm init"

apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
apiServer:
  extraArgs:
    cloud-provider: "aws"
controllerManager:
  extraArgs:
    cloud-provider: "aws"

I got an error message saying that aws has been depreciated

I used the same file with the cloud-provider changed to "openstack"

Still I am getting errors; looks like the new version of Kubernetes I need to use another parameter "cloud-config" which has the configuration

Can anyone help me on how this needs to be done and how I can successfully configure a k8 cluster using EC2.

Referring from here You can use below config for AWS.

apiVersion: kubeadm.k8s.io/v1beta2
kind: InitConfiguration
nodeRegistration:
  kubeletExtraArgs:
    cloud-provider: "openstack"
    cloud-config: "/etc/kubernetes/cloud.conf"
---
apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: v1.13.0
apiServer:
  extraArgs:
    cloud-provider: "openstack"
    cloud-config: "/etc/kubernetes/cloud.conf"
  extraVolumes:
  - name: cloud
    hostPath: "/etc/kubernetes/cloud.conf"
    mountPath: "/etc/kubernetes/cloud.conf"
controllerManager:
  extraArgs:
    cloud-provider: "openstack"
    cloud-config: "/etc/kubernetes/cloud.conf"
  extraVolumes:
  - name: cloud
    hostPath: "/etc/kubernetes/cloud.conf"
    mountPath: "/etc/kubernetes/cloud.conf

And then you can do kubeadm init --config=kubeadm-config.yml

You could avoid all of these if you just used Kops to install kubernetes on AWS.
