[Kubernetes] Changing DNS or Hosts of the POD on Kubernetes

Posted on April 2, 2022 By nim No Comments on [Kubernetes] Changing DNS or Hosts of the POD on Kubernetes

Trên máy tính thì anh em có thể dễ dang add 1 domain với IP vào file host
Vậy làm việc này với các pod trên kubernetes thì sao?

Example:

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"
  containers:
  - name: cat-hosts
    image: busybox:1.28
    command:
    - cat
    args:
    - "/etc/hosts"
