Can I stop my kubeconfig file from expiring every 7 days?

Same question, looks like a showstopper for us - can’t use DO Kubernetes until this is resolved

Relevant: https://www.digitalocean.com/docs/kubernetes/overview/#known-issues

The certificate authority, client certificate, and client key data in the kubeconfig.yaml file are rotated weekly. If you run into errors like the server doesn’t have a resource type “<resource>”, Unauthorized, or Unknown resource type: nodes, try downloading a new cluster configuration file. The certificates will be valid for one week from the time of the download.

I talked to support about this, and it seems that they classified this as an actual Issue their engineers are working on. Also this apperantely is probably one of many blockers for Kubernetes Services getting out of LTD.

so here is what i did - a simple script to grant the default service account cluster-admin role. i am not guaranteeing this is secure or anything - use at your own risk. let’s see if markdown works fora code block here in the comments.

#!/bin/bash


NAMESPACE=default
SA_NAME=default
CRB_NAME=sa-admin
CONTEXT=digitalocean # this is not the default I edited my kubeconfig after download

cat > /tmp/clusterrolebinding.yaml <<EOF
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: ${CRB_NAME}
subjects:
  - kind: ServiceAccount
    name: ${SA_NAME}
    namespace: ${NAMESPACE}
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
EOF

kubectl create -f /tmp/clusterrolebinding.yaml

SECRET_ID=$(kubectl get secrets --namespace $NAMESPACE | awk "/$SA_NAME/"'{print $1}')
TOKEN=$(kubectl get secrets $SECRET_ID -n $NAMESPACE -o json | jq '.data.token' | tr -d '"' | base64 -D)

kubectl config set-credentials $SA_NAME --token=$TOKEN
kubectl config set-context ${CONTEXT} --user ${SA_NAME} --namespace ${NAMESPACE}

so I had the same question and what I am going to try is to create a service account, assign it cluster-admin rbac rights, then update the kubeconfig using this service account’s token. i’ll post again here if it all works.
