二、部署Istio
wget https://github.com/istio/istio/releases/download/1.13.3/istio-1.13.3-linux-amd64.tar.gz
tar xf istio-1.13.3-linux-amd64.tar.gz
ln -sf istio-1.13.3/bin/istioctl /usr/local/bin/
# 安装
istioctl install -y --set profile=demo
✔ Istio core installed
✔ Istiod installed
✔ Ingress gateways installed
✔ Egress gateways installed
✔ Installation complete Making this installation the default for injection and validation.
Thank you for installing Istio 1.13. Please take a few minutes to tell us about your install/upgrade experience! https://forms.gle/pzWZpAvMVBecaQ9h9
