feat: add dnsEndpoints peer discovery source#57
Merged
Conversation
Add DNSEndpointsSource to the discover-peers handler. The controller resolves Kubernetes SeiNode label selectors to stable pod DNS names and passes them as dnsEndpoints sources. The sidecar queries each endpoint's Tendermint RPC for the node ID and builds peer addresses. - Add DNSEndpointsSource with Discover() that queries :26657/status - Add Endpoints field to PeerSourceEntry - Wire dnsEndpoints type into buildSources dispatcher - Add PeerSourceDNSEndpoints constant and client support Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- TestDNSEndpointsSource_Discover — resolves 2 endpoints with mock querier - TestDNSEndpointsSource_SkipsUnreachable — skips failed endpoint, returns reachable - TestDNSEndpointsSource_AllUnreachable_ReturnsError — fails when no endpoints reachable - TestHandler_SourcesParam_DNSEndpoints — full handler integration with config.toml write Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
defaultQueryNodeID already appends :26657 in the URL template. Passing endpoint+":26657" produced http://host:26657:26657/status. Tests updated to use bare hostnames matching the querier contract. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Add
DNSEndpointsSourceto the discover-peers handler. The controller resolves Kubernetes SeiNode label selectors to stable pod DNS names and passes them asdnsEndpointssources. The sidecar queries each endpoint's Tendermint RPC for the node ID and builds peer addresses.Named
dnsEndpoints(notkubernetesLabel) so the sidecar stays infrastructure-agnostic — it receives DNS hostnames and makes HTTP calls, no Kubernetes API access needed.Companion controller PR: sei-protocol/sei-k8s-controller#47
