From 792dbc172e7831b8ce17a0e611dd52e132b0a9cd Mon Sep 17 00:00:00 2001 From: Kenny Udovic Date: Sat, 17 Jan 2026 07:20:38 -0500 Subject: [PATCH] fix: correct vIP filtering logic from 0.1.4 The 0.1.4 fix incorrectly filtered ALL endpoints from the nodes list, which removed control plane nodes that legitimately appear in both. This broke configs like: - endpoints: [vip, cp1, cp2, cp3] - nodes: [cp1, cp2, cp3, w1, w2] The corrected logic now only filters endpoints that are NOT also in the nodes list (true vIPs/load balancers). Control plane nodes appearing in both lists are preserved. Also fixed kubeconfig and etcd APIs to not use node targeting - these only run on control plane nodes, so targeting workers returned empty results. Added log noise filtering for HTTP/gRPC libraries. --- Cargo.toml | 2 +- crates/talos-rs/src/client.rs | 264 +++++++++++++++++----- src/main.rs | 16 +- test-clusters/scripts/setup-vip-config.sh | 118 ++++++---- 4 files changed, 298 insertions(+), 102 deletions(-) diff --git a/Cargo.toml b/Cargo.toml index 1556c97..3e0a8e4 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -3,7 +3,7 @@ members = ["crates/*"] resolver = "2" [workspace.package] -version = "0.1.4" +version = "0.1.5" edition = "2024" authors = ["Ken Udovic"] license = "MIT" diff --git a/crates/talos-rs/src/client.rs b/crates/talos-rs/src/client.rs index 4a7fad7..88eb82e 100644 --- a/crates/talos-rs/src/client.rs +++ b/crates/talos-rs/src/client.rs @@ -118,24 +118,37 @@ impl TalosClient { // Only add nodes metadata if explicitly configured (not just endpoints) // When nodes is empty or same as endpoints, skip the header if !self.nodes.is_empty() { - // Filter out localhost/127.0.0.1 entries as these are endpoint proxies - // Also filter out entries that match endpoints (likely vIPs) + // Identify vIPs: endpoints that are NOT in the nodes list + // These are load balancers/VIPs that shouldn't be targeted as nodes + // Endpoints that ARE also in nodes are real nodes and should be kept + let vips: std::collections::HashSet<&str> = self + .endpoints + .iter() + .filter_map(|e| { + let endpoint_host = e.split(':').next().unwrap_or(e);
