#k8s 修改时区
##第一种是把主机的时区文件挂载到pod内
<code>vi time-pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: nginx-tz
namespace: default
labels:
app: my-pod
spec:
containers:
- name: my-tz
image: harbor.mvmyun.com/dev/nginx
ports:
- containerPort: 80
volumeMounts:
- name: timezone
mountPath: /etc/localtime
readOnly: true
imagePullSecrets:
- name: regcred
volumes:
- name: timezone
hostPath:
path: /usr/share/zoneinfo/Asia/Shanghai/<code>
#第二种是使用PodPreset来预设
<code>vim /etc/kubernetes/manifests/kube-apiserver.yaml
- --enable-admission-plugins=NodeRestriction,DefaultStorageClass,PodPreset
- --runtime-config=settings.k8s.io/v1alpha1=true/<code>
<code>vim podpreset.yaml
apiVersion: settings.k8s.io/v1alpha1
kind: PodPreset
metadata:
name: tz-env
spec:
selector:
matchLabels: #matchLabels 为空 表示应用所有容器
env:
- name: TZ
value: Asia/Shanghai/<code>
#查看已创建的podpresets
kubectl get podpresets
####注意： PodPreset是针对ns的 不是全局！
#在dockerfile中修改
Alpine
<code>RUN apk --no-cache add tzdata && \\
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \\
echo "Asia/Shanghai" > /etc/timezone /<code>
--no-cache参数不缓存文件，有助于减少最终体积。
Ubuntu
<code>RUN echo "Asia/Shanghai" > /etc/timezone && \\
dpkg-reconfigure -f noninteractive tzdata/<code>
CentOS
<code>RUN echo "Asia/shanghai" > /etc/timezone;/<code>
