How do you go about upgrading a Kubernetes cluster based on kops/aws?

Question

Amazon Web Services

Hello everyone,

I know the question is very broad, but I would like to ask how best to upgrade cluster based on k8s 1.11.6 (etcd version 2) to k8s 1.15?

What to update first, in what order? I read that using kops edit is not the best idea! Is it possible to upgrade the master node first?

Answer 1

kops edit/update updates the cluster fine.
I would advise you to update one version at a time and each time check if something has gone wrong in the deployment configs, etc. For k8s, the api changes, and some of your customization can fly into the pipe.
k8s 1.11 already has support for etcd3 - I would start by updating etcd to the recommended 3.2.10+ and mentally prepare to edit deployments.

Answer 2

Not an answer, but I will write step by step:

1. Transferring infrastructure to ECS
   
2. Throw out k8s
   
3. We get praise for saving the company a lot of money and nerves.
   

The k8s solution at AWS was created to help companies with it move to their cloud more easily. Everything, one task. Further it is useless in AWS. In other clouds, everything is fine, they do not have normal managers
