#31659 new defect

new onionoo hosts

Reviewer: Sponsor:


Right now we have two onionoo backends (that run the java stuff) and also serve users, and two additional frontend-only hosts (that only serve users and ask the backends if they don't have a cached answer). So we have 4 hosts in total, two of which serve a double role.

To make the setup easier to monitor, scale, and maintain we should split these roles. For communications between frontends and backends we'll switch to using ipsec rather than the stunnels.

As a first step, we'll set up a new backend-only host (on Debian 10/buster) and Iain will set up the service there.

Onionoo on oo-hetzner-03 and on omeiense use about 40gb (each) of disk space and about 8-9GB of ram.

irl, the host should be ready for you.

I suggest you use systemd user services instead of @reboot cronjobs. lingering is already enabled for both roles.

Please let us know when we can proceed.

Adding to the Metrics roadmap, but probably for next week's sprint at the earliest.
