From c82070f045e5d636a389089b06bdde53362b5340 Mon Sep 17 00:00:00 2001 From: thc1006 <84045975+thc1006@users.noreply.github.com> Date: Wed, 1 Oct 2025 12:11:46 +0800 Subject: [PATCH 1/2] feat(backend): Add driver pod labels/annotations configuration support Fixes #12015 Add the ability to specify driver pod labels and annotations as a KFP API server configuration to support Istio STRICT mTLS and other infrastructure requirements. Changes: - Add driver configuration reader in apiserver/config - Modify Argo compiler to apply labels/annotations to driver pods - Update deployment manifests with ConfigMap support - Add Istio STRICT mTLS overlay configuration - Add E2E tests for Istio integration - Add comprehensive documentation This allows administrators to configure driver pods with custom labels and annotations at deployment time, enabling proper sidecar injection for service mesh environments without requiring SDK changes.
