Anastasia Lubennikova 92214578af Fix proxy_io_bytes_per_client metric: use branch_id identifier properly. (#4084)
It fixes the miscalculation of the metric for projects that use multiple
branches for the same endpoint.
We were under billing users with such projects. So we need to
communicate the change in Release Notes.

Proxy

Proxy binary accepts --auth-backend CLI option, which determines auth scheme and cluster routing method. Following backends are currently implemented:

  • console new SCRAM-based console API; uses SNI info to select the destination project (endpoint soon)
  • postgres uses postgres to select auth secrets of existing roles. Useful for local testing
  • link sends login link for all usernames

Using SNI-based routing on localhost

Now proxy determines project name from the subdomain, request to the round-rice-566201.somedomain.tld will be routed to the project named round-rice-566201. Unfortunately, /etc/hosts does not support domain wildcards, so I usually use *.localtest.me which resolves to 127.0.0.1. Now we can create self-signed certificate and play with proxy:

openssl req -new -x509 -days 365 -nodes -text -out server.crt -keyout server.key -subj "/CN=*.localtest.me"

start proxy

./target/debug/proxy -c server.crt -k server.key

and connect to it

PGSSLROOTCERT=./server.crt psql 'postgres://my-cluster-42.localtest.me:1234?sslmode=verify-full'
