How to set disk size for Kubernetes minions on AWS?

I'm trying to setup kubernetes on aws. I want to use t2.micro instances for minions. But the disk size is too small(8GB). How can I change the disk size for minions?

In order to set the disk size for Kubernetes minions on AWS, you will need to SSH into each individual minion and modify the /etc/kubernetes/manifests/kube-apiserver.yaml file. Within this file, you will need to find the --storage-backend flag and set its value to aws. Next, save and close the file. Finally, run the following command to apply the changes:

kubectl apply -f /etc/kubernetes/manifests/kube-apiserver.yaml

This will update the size of the respective disks for all of the minions in the Kubernetes cluster.

Setting the disk size for Kubernetes minions on AWS needs to occur before the creation of the cluster. This is because each node has its own pre-defined disk size.

Here are the steps to configure the disk size of Kubernetes minions on AWS:

Go to the AWS console and select the EC2 service.
Go to the EC2 dashboard and select “Launch Instances”.
From the list of instance types, select the one that is suitable for your application and configure the size of the instance. Make sure to add extra storage for the Kubernetes cluster.
In the “Configure Instance” step, select the “EBS-optimized” button and select the “Max I/O Optimized” option.
Select the disk size you want for the Kubernetes minions from the “Root Volume Type” drop down list.
Proceed through the other configuration steps to complete the process for adding/modifying disk size for Kubernetes minions on AWS.
