Extending TTL of session on the Kubernetes dashboard

The kubernetes dashboard ttl for authentication is a bit too short. To extend it run...

kubectl edit deployment kubernetes-dashboard -n kube-system

In some versions, the kubernetes-dashboard deployment is in the kubernetes-dashboard namespace.

Go down to the part that has...

      containers:
      - args:
        - --auto-generate-certificates
        - --namespace=kube-system

And add this in...
        - --token-ttl=86400

Where 86400 is the TTL (in seconds) you want to have.

Save the file, it auto-applies. Can take up to 30 minutes to see and able to use again though
