Kubernetes Cluster is unreachable

My app runs kubernetes cluster with 2 droplets. But now kubernetes throws 500 error and does not work. I tried to remove kubernetes and its droplets but then it gives me this error: “13 INTERNAL: dialing for agent, agent unavaiable.”

Hello,

Do you see any errors in the logs? And also if you check the status of your nodes do you get any more information rather than the 500 error?

What I could suggest is following the steps from this tutorial here and setting up an unmanaged cluster from scratch:

https://www.digitalocean.com/community/tutorials/how-to-create-a-kubernetes-cluster-using-kubeadm-on-ubuntu-20-04

Alternatively, you could give the Managed Clusters a try which would allow you to not have to worry about the server management at all:

Best,

Kubernetes is a container orchestration system that manages containers at scale. Initially developed by Google based on its experience running containers in production, Kubernetes is open source and actively developed by a community around the world. In this guide, you will set up a Kubernetes cluster from scratch using Ansible and Kubeadm, and then deploy a containerized Nginx application to it.
  • Hello, when I try to remove kubernetes cluster it gives mi these errors:
    “/graphql:1 Failed to load resource: the server responded with a status of 503 ” and “Failed to load resource: net::ERRBLOCKEDBY_CLIENT”. So I couldn’t reach cluster or remove it.
