Question

我在minikube上安装了istio并部署了示例应用程序。

一切正常，除了我无法在微服务之间获得请求。

产品服务正在监听：9080 /产品路线。

我尝试过的网址：

“产品：9080 /产品”
“博客产品：9080 /产品”

但是他们都不行。

await axios.get('products:9080/products')
await axios.get('blog-products:9080/products')

如果我运行此命令，它将起作用，但是当我尝试在microservice-1中运行该URL时，它将不起作用。

kubectl exec -it $(kubectl get pod -l app=products -o jsonpath='{.items[0].metadata.name}') -c products -- curl products:9080/products

blog.yaml用于服务定义
