cloudpi4 is a wired Raspberry Pi 4 on the Anchor network, folly's network for lab hosts. It is a test DNS resolver and an iperf3 server. nix/hosts/cloudpi4.nix configures it.
What it runs#
- CoreDNS with the resolver config of capsule and spore, from
nix/services/coredns-sinkhole.nix. DHCP does not offer cloudpi4 as a DNS server, so it answers only clients configured to use it. See Lab DNS and time. - An iperf3 server for netbench
- A node exporter, which
clusters/folly/monitoring/local-node-exporters.yamldeclares as a Prometheus target on folly

- HostsEvery host in the homelab, with its role, site, hardware, OS and status, and how to reach it.
- Ingress and DNSThe Gateways, DNS records, certificates, tunnels and lab resolvers that give cluster services a name and a path from the LAN, tailnet or internet.
