## Using ECC Workload Certificates ## (pilot-agent environmental variables) Jacob Delgado / Aspen Mesh ## I stioCon ## ECC workload certificates - In various environments, the need for x509 certificates use ECC cryptography (using ECDSA P-256) to use this feature • Only ECDSA P-256 is supported ## pilot-agent environmental variables Disclaimer: Environmental variables and their use are considered experimental must set the ECC_SIGNATURE_ALGORITHM environmental variable on sidecar ejection to ECDSA for use by pilot-agent ☐ For gateways this environmental variable also must be set on installation/upgrade ## istioctl

Recently, cause of ram pilot OOM. At the same time, envoy return 503 and the response flag is NR. 2024/1/10 2024/1/10 2024/1/10 2024/1/10 2024/1/10 when pilot restarting, the route is ok, and return 200. Expected behavior How to avoid this scenes, when pilot OOM restart, not affect envoy route. Steps to

management services for Istio. mixc Utility to trigger direct calls to Mixer's API. pilot-agent Istio Pilot agent. ✓ istio_ca Istio Certificate Authority (CA). ✓ istio control interface per-node agent. pilot-discovery Istio Pilot. ✓ pilot-discovery Istio Pilot. sidecar-injector Kubernetes webhook for automatic Istio sidecar injection. ## Pilot-Agent——管理生命周期（PA） 启动 admin (2) get listen sockets (3) start drain (4) fetch stats (5) terminate parent ## 热重启涉及以下步骤 • Pilot-Agent只是负责启动S，其他步骤由envoy完成。 • 1. 启动另外一个S进程（Secondary process） • 2. S通知P（Primary process）关闭其管理的端口，由S接管
