我正在尝试在具有一个头节点和两个工作节点的kubeadm上使用指标服务器,但我不断收到未知的hostAliases错误

最佳答案

您的YAML文件结构似乎有误,HostAliases应该采用这样的结构

apiVersion: v1
kind: Pod
metadata:
name: hostaliases-pod
spec:
restartPolicy: Never
hostAliases:
- ip: "127.0.0.1"
hostnames:
- "foo.local"
- "bar.local"
- ip: "10.1.2.3"
hostnames:
- "foo.remote"
- "bar.remote"

注意,在hostAliases输入之后,您应该输入 - ip: "127.0.0.1"在放置将解析为该IP的主机名之后。

您的YAML是
hostAliases: 
- hostnames:
- k8s-head
ip: "192.168.205.10"
- hostnames:
- k8s-node-1
ip: "192.168.205.11"
- hostnames:
- k8s-node-2
ip: "192.168.205.12"
