I'm very new to kubernetes and all I want to do at this point is restart my cluster and have it run an updated dockerfile. I'm running kubernetes in google-cloud-platform by the way.

kubectl from version 1.15 should contain kubectl rollout restart
(according to this comment https://github.com/kubernetes/kubernetes/issues/33664#issuecomment-497242094)
You can use kubectl patch to trigger a redeploy for example adding a new label.
$ kubectl patch deployment your_deployment -p "{\"spec\": {\"template\": {\"metadata\": { \"labels\": { \"redeploy\": \"$(date +%s)\"}}}}}"
And now you should see a new ReplicaSet trying to deploy new pods for you!

(I also made it into a shortcut that can apply it to all deploys that match some sort of filter)
