How Can I Copy File to Minikube Pod - docker

Question

I want to copy a text file to a pod on minikube. But I get the timeout error.
scp -r /Users/joe/Downloads/Archive/data.txt docker#192.168.49.2:/home/docker
I got the ip address (192.168.49.2) with:
minikube ip
Eventually I would like that the file appear on the persistentVolumeClaim/persistentVolume (that will be great!!)
The yaml for the PersistentVolume is:
kind: PersistentVolume
apiVersion: v1
metadata:
name: my-pv
spec:
storageClassName: local-storage
capacity:
storage: 1Gi
accessModes:
- ReadWriteOnce
hostPath:
path: "/mnt/data"
The yaml for the PersistentVolumeClaim is:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: my-pvc
spec:
storageClassName: local-storage
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 512Mi
The yaml for the pod is:
kind: Pod
apiVersion: v1
metadata:
name: my-pvc-pod
spec:
containers:
- name: busybox
image: busybox
command: ["/bin/sh", "-c", "while true; do sleep 3600; done"]
volumeMounts:
- mountPath: "/mnt/storage"
name: my-storage
volumes:
- name: my-storage
persistentVolumeClaim:
claimName: my-pvc

Eventually I would like that the file appear on the persistentVolumeClaim/persistentVolume.
You can achieve that with mounting the host directory into the guest using minikube mount command:
minikube mount <source directory>:<target directory>
Whereas the the <source directory> is the host directory and <target directory> is the guest/minikube directory.
And then use that <target directory> and create pv with hostPath:
apiVersion: v1
kind: PersistentVolume
metadata:
name: task-pv-volume
spec:
storageClassName: manual
capacity:
storage: 10Gi
accessModes:
- ReadWriteOnce
hostPath:
path: "<target-directory"
Depending also driver, some of them have built-in host folder sharing. You can check them here.
If you need to mount only part of the volume, in your case a single file, you can use subPath to specify the part that must be mounted. This answer explains it well.
