Question

我有两个容器（Nginx和Busybox）在同一命名空间的不同容器中运行。每当我尝试从busybox pod到Nginx进行ping或wget时，我都无法做到这一点，并且我无法理解为什么会发生这种情况，因为我应该能够从Pod与另一个进行通信。

Ngnix Pod说明

apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    run: nginx
  name: nginx
spec:
  containers:
  - image: nginx
    name: nginx
    ports:
    - containerPort: 80
    resources: {}
  dnsPolicy: ClusterFirst
  restartPolicy: Never
status: {}

BusyBox Pod说明

apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    run: busybox
  name: busybox
spec:
  containers:
  - image: busybox
    name: busybox
    resources: {}
  dnsPolicy: ClusterFirst
  restartPolicy: Never
status: {}

终端放置：

wget -O- 172.XX.XX.XXX:XX
Connecting to 172.XX.XX.XXX:XX (172.XX.XX.XXX:XX)
wget: can't connect to remote host (172.XX.XX.XXX): Connection timed out

在登录时我得到了

2019/07/12 18:47:30 [error] 7#0: *1177 "/usr/local/nginx/html/nginx_status/index.html" is not found (2: No such file or directory), client: 127.0.0.1, server: localhost, request: "GET /nginx_status/ HTTP/1.1", host: "localhost"

Answer 1

您提到的nginx日志中的404错误看起来像来自客户端客户端说的localhost一样来自nginx主机。它与您的连接超时错误无关。

您如何找到Pod的群集IP？通常，您可以使用以下命令获取IP地址：

kubectl get pods -o wide

检查wget命令中使用的IP是否正确。

通过busybox pod进行ping操作时，无法从nginx pod获得响应
