openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=*"

gcloud beta compute ssl-certificates create l7-xlb-cert \
--certificate=tls.crt \
--private-key=tls.key \
--region=us-west4

gcloud beta compute target-https-proxies create l7-xlb-proxy-https \
--url-map=regional-l7-xlb-map-https \
--region=us-west4 \
--ssl-certificates=l7-xlb-cert

gcloud beta compute forwarding-rules create l7-xlb-forwarding-rule-https \
--load-balancing-scheme=EXTERNAL_MANAGED \
