k8s組件時區修改

一、etcd、apiserver、controller-manager、scheduler時區修改

1、修改master服務器上/etc/kubernetes/manifests/目錄下的yaml文件

[root@master ~]# ll /etc/kubernetes/manifests/
total 16
-rw------- 1 root root 2361 May 10 10:53 etcd.yaml
-rw------- 1 root root 3522 May 10 10:49 kube-apiserver.yaml
-rw------- 1 root root 2976 May 10 10:53 kube-controller-manager.yaml
-rw------- 1 root root 1562 May 10 10:52 kube-scheduler.yaml

　　

2、在yaml中掛載服務器的時區(內容如下）

volumeMounts:
  - mountPath: /etc/localtime
    name: host-time
    readOnly: true
volumes:
- hostPath: 
    path: /etc/localtime
  name: host-time

　　

3、查看修改后的kube-apiserver.yaml（其它幾個文件都一樣的修改）

[root@master ~]# cat  /etc/kubernetes/manifests/kube-apiserver.yaml |tail  -32
    volumeMounts:
    - mountPath: /etc/ssl/certs
      name: ca-certs
      readOnly: true
    - mountPath: /etc/pki
      name: etc-pki
      readOnly: true
    - mountPath: /etc/kubernetes/pki
      name: k8s-certs
      readOnly: true
    - mountPath: /etc/localtime
      name: host-time
      readOnly: true
  hostNetwork: true
  priorityClassName: system-node-critical
  volumes:
  - hostPath:
      path: /etc/ssl/certs
      type: DirectoryOrCreate
    name: ca-certs
  - hostPath:
      path: /etc/pki
      type: DirectoryOrCreate
    name: etc-pki
  - hostPath:
      path: /etc/kubernetes/pki
      type: DirectoryOrCreate
    name: k8s-certs
  - hostPath: 
      path: /etc/localtime
    name: host-time
status: {}

　　

二、修改kube-proxy的時區

1、直接edit kube-proxy的ds配置(掛載參數和上面一樣)

kubectl edit  ds -n kube-system kube-proxy 

　　

 

三、修改coredns時區

1、edit coredns配置，直接掛載服務器時區

kubectl edit deploy -n kube-system coredn
