4.3 网络插件故障排查
网络插件故障排查：
podman logs fgedu-cilium
level=info msg=”Starting Cilium agent…”
level=info msg=”Initializing daemon”
level=info msg=”Establishing connection to apiserver”
level=info msg=”Connected to apiserver”
level=info msg=”Initializing network”
level=info msg=”Network initialization complete”
level=info msg=”Cilium agent ready”
# 检查CNI配置
