curl - 无法从主机建立与 minikube 集群的连接

Question

我正在远程裸机实例上关注这个裂变教程。当我运行 curl $FISSION_URL ( http://192.168.42.152:31313 ) 时，它不会返回。我运行了以下命令：

1. 须藤 lsof -i | grep 192.168.42.152。

ntpd 2860 ntp 32u IPv4 55241 0t0 UDP 192.168.42.1:ntp

dnsmasq 3392 libvirt-dnsmasq 5u IPv4 33870 0t0 UDP 192.168.42.1：域

dnsmasq 3392 libvirt-dnsmasq 6u IPv4 33871 0t0 TCP 192.168.42.1:domain (LISTEN)

2. 卷曲-vvv $FISSION_URL。

我不确定我应该如何进行调试。我相信主机能够与来宾（minikube IP）连接但无法检索数据。谁能指导我如何解决这个问题？

Answer 1

启动 minikube 实例并运行文档中给出的命令后

kubectl create -f http://fission.io/fission.yaml
kubectl create -f http://fission.io/fission-nodeport.yaml

然后运行以下设置 kubernetes 上下文

kubectl config set-context minikube --namespace fission

现在要获取刚刚运行的当前部署的状态，请发布以下命令的输出：

kubectl get pods -o wide
kubectl get svc -o wide
kubectl get events 

---

对我来说它正在工作：

$ export FISSION_URL=http://$(minikube ip):31313
$ curl $FISSION_URL
{"message": "Fission API", "version": "0.1.0"}

我的状态如下所示：

$ kubectl get pods -o wide
NAME                           READY     STATUS    RESTARTS   AGE       IP           NODE

poolmgr-3531518326-nsxmr       1/1       Running   3          16m       172.17.0.5   minikube

和

$ kubectl get svc -o wide
NAME         CLUSTER-IP   EXTERNAL-IP   PORT(S)        AGE       SELECTOR
controller   10.0.0.191   <nodes>       80:31313/TCP   15m       svc=controller

poolmgr      10.0.0.252   <none>        80/TCP         16m       svc=poolmgr
router       10.0.0.108   <nodes>       80:31314/TCP   15m       svc=router
