The key within the token secret has changed.

Great project. We found this out of necessity as noted in the README. One issue we encountered though with recent versions of the agent is the key within the token secret is gateway-key and not value:

-OUTPUT=$(kubectl --namespace $NAMESPACE create secret generic ${TOKEN_SECRET} --from-literal value="GatewayKey ${TOKEN}" --dry-run=client -o yaml 2>&1 | kubectl --namespace $NAMESPACE apply -f - 2>&1) || {
+OUTPUT=$(kubectl --namespace $NAMESPACE create secret generic ${TOKEN_SECRET} --from-literal gateway-key="GatewayKey ${TOKEN}" --dry-run=client -o yaml 2>&1 | kubectl --namespace $NAMESPACE apply -f - 2>&1) || {

Making the above change and the script worked for us.
