minikube + hostPath
minikube + hostPath
提问于 2021-09-27 08:22:20
我不顾一切地试图应用一个简单的pod规范，而没有任何运气，即使有了以前的答案：Mount local directory into pod in minikube。
yaml文件：
apiVersion: v1
kind: Pod
metadata:
name: hostpath-pod
spec:
containers:
- image: httpd
name: hostpath-pod
volumeMounts:
- mountPath: /data
name: test-volume
volumes:
- name: test-volume
hostPath:
# directory location on host
path: /tmp/data/我用：minikube start --mount-string="/tmp:/tmp" --mount启动了minikube集群，/tmp/data中有3个文件
ls /tmp/data/
file2.txt file3.txt hello然而，当我做kubectl describe pods时，这就是我得到的

Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default有什么我可以尝试的吗？

- 从
minikube转变为microk8s起到了帮助作用。但是我仍然没有看到/data/里面的任何东西， - 也从
/tmp/变成了minikube中的另一个文件夹。与MacOs有关.

OP曾经说过，这个问题已经解决了：
从/tmp/转换到另一个文件夹的
在minikube中起到了帮助作用。因为某种原因，minikube不喜欢
/tmp/，所以与MacOs有关
对此问题的解释：您不能将/tmp挂载到/tmp。问题不在于macOS，而在于您的方式。我试着用几种方法重现这个问题。我用了一个码头，得到了一个非常有趣的错误：
docker: Error response from daemon: Duplicate mount point: /tmp.这个错误清楚地说明了问题的所在。如果您将目录挂载到其他地方，则所有内容都应该正常工作(这已得到确认)：
我是否正确地理解，当您将挂载点更改为另一个文件夹时，它是否有效？这是正确的。由于某种原因，minikube不喜欢
/tmp/
我知道在我的例子中，您使用的是hyperkit而不是docker，但是唯一的区别将是您在屏幕上得到的消息。就码头工人而言，这是非常清楚的。
