Now that we have effective global sessions thanks to #2734, there is no
longer a need to keep the number of pods on the EPP service static.
We are also not vulnerable to random pod restarts. K8s never guarantees
perpetual pod lifetime anyway, and not having to be at its mercy is
certainly a relief.
This allows us to easily tell which tag was deployed.
Also set the gateway to use named address so they are stable, and so
that we can attach an IPv6 record to it. Auto-provisioned addresses are
IPv4 only.
We are required to respond to HTTP(S) requests on port 80/443 on the
same domain where we serve port 43 WHOIS requests. The proxy already
does this by redirecting to the web WHOIS lookup page on the marketing
website.
This PR makes it so that requests to port 80/443 can be routed to the
proxy for redirect.
TESTED=tested on crash and the redirect works.
k8s does not have a way to expose a global load balancer with TCP
endpoints, and setting up node port-based routing is a chore, even with
Terraform (which is what we did with the standalone proxy).
We will use Cloud DNS's geolocation routing policy to ensure that
clients connect to the endpoint closest to them.
For reasons unclear to me, if the stack trace is appended directly to
the message, the log entry will be lumped together with following logs
on GKE.
Also updated the GKE service account for Nomulus in the manifest so we
can use workload identity just for Nomulus, not other pods on the same
cluster.
