The initial two-VM run against a real Proxmox host found three real
bugs in the obmp-docker stack, plus one design issue in this test:
Fixed in obmp-docker (deploy-refinement branch):
- 745f066 deploy.sh: probe sudo with `sudo -n true` instead of
`sudo -v` / `sudo -n -v`; the latter demands a credential
timestamp that NOPASSWD never produces, so both fail on
cloud-init / CI even with NOPASSWD:ALL configured.
- 6df67a7 .env.example: quote GNMI_ADDRESSES with single quotes so
docker compose's .env parser doesn't choke on the mid-line
comma in the double-quoted list form.
Fixed here:
- bmpgen cloud-init: add `port = 1179` under [global.config] to
avoid gobgpd's 179 listener bind failing under Ubuntu 24.04 +
Docker even with --network host and default NET_BIND_SERVICE cap.
We don't accept BGP peers on bmpgen so the port value doesn't
matter as long as it's unprivileged.
- run-test.sh: fix column name for bgp_peers.state -- the opstate
enum uses lowercase 'up', not uppercase 'UP'.
Verified against the live run: 6/6 assertions pass, ip_rib landed
251,760 routes from the store VM's own gobgp connecting to Bromirski's
public full-table feed via --profile test.

# VM B -- GoBGP standing in for a real BGP router. Cloud-init installs

# only after the store VM boots and its qemu-guest-agent reports). That
|
|
# reference creates an implicit dependency, so bmpgen's snippet upload +
|

# VM creation both wait until the store's address is known.
