# shows how kubernetes kubeproxy can select backends based on which port of a multi-port service is being accessed
# nginx is only listening on port 80
# kuard is only listening on port 8080
# the partial-ports service exposes both 80 and 8080
# 
# kubectl -n foo run -it --rm --restart=Never --image=curlimages/curl:7.76.1 test1 -- curl partial-ports:80
# and
# kubectl -n foo run -it --rm --restart=Never --image=curlimages/curl:7.76.1 test1 -- curl partial-ports:8080
# both succeed 100% of the time
