[英]Kubernetes Port Forwarding - Connection refused
轉發端口時出現以下錯誤。 任何人都可以幫忙嗎？
mjafary$ sudo kubectl port-forward sa-frontend 88:82
Forwarding from 127.0.0.1:88 -> 82
Forwarding from [::1]:88 -> 82
錯誤日志：

這是 pod 的描述。 我的期望是，當我在瀏覽器中點擊 localhost:88 時，請求應該轉發到 jafary/sentiment-analysis-frontend 容器並且應用程序頁面應該加載

正如帕特里克正確指出的那樣。 我遇到了同樣的問題，困擾了我 2 天。 所以步驟是：
kubectl port-forward pod/my-name-of-pod 8080:5000
