我全新安装了在 MacOS Mojave 上运行的 minishift (v1.32.0+009893b)。
我用 4 个 CPU 和 8GB RAM 开始 minishift：
minishift start --cpus 4 --memory 8GB我已按照说明准备此处描述的 Openshift (minishift) 环境：https ://istio.io/docs/setup/kubernetes/prepare/platform-setup/openshift/
我已经按照文档安装了 Istio，没有任何错误：https ://istio.io/docs/setup/kubernetes/install/kubernetes/
