我已经设法使用 kubernetes-version='v1.13.11' 在 minikube 上运行 KeyCloak 和 Kong。
我正在使用这个版本，因为我想最终部署到 GCP 集群。
当我尝试打开 PROXY_IP:HTTP_PORT/auth 时，我得到以下响应：
**"Kong Error An invalid response was received from the
upstream server."**
我认为我应该得到的是 KeyCloak 主页。
重现步骤：
minikube start --kubernetes-version='v1.13.11'kubectl apply -f keycloack.yamlkubectl apply -f kong-all-in-one.yamlkubectl apply -f kong-ingress.yamlexport PROXY_IP=$(minikube service kong-proxy --url --format "{{ .IP }}" | head -1)export HTTP_PORT=$(minikube service kong-proxy --url --format "{{ .Port }}" | head -1)- 访问
$PROXY_IP:$HTTP_PORT/auth
