Mount local directory into pod in minikube
I found a way.
This way you can directly mount directory to container. You do not have to mount your directory to minikube first.
We can specify the directory we want to add into container by using hostPath
in volumes
volumeMounts:
- name: crypto-config
mountPath: <PATH IN CONTAINER>
- name: channel-artifacts
mountPath: /opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts
- name: chaincode
mountPath: /opt/gopath/src/github.com/chaincode
volumes:
- name: crypto-config
hostPath:
path: <YOUR LOCAL DIR PATH>
- name: channel-artifacts
hostPath:
path: /Users/akshaysood/Blockchain/Kubernetes/Fabric/network/channel-artifacts
- name: chaincode
hostPath:
path: /Users/akshaysood/Blockchain/Kubernetes/Fabric/network/chaincode
DefaultMountDir
Minikube already mounts by default home directory to VM:
- on Mac it mounts dir of all users -
/Users
- on Linux and Windows just the home of current user -
homedir.HomeDir()
You can see how it does this, if you browse through Minikube sources.
Here is the search for the moment, but result might change over time:

The definition of the HomeDir()
is:
https://godoc.org/k8s.io/client-go/util/homedir
You can always do minikube ssh
into the Minikube VM and explore it:
$ df -hl
Filesystem Size Used Avail Use% Mounted on
...
/Users 466G 442G 25G 95% /Users
As Minikube is a single node Kubernetes cluster, you can then mount /Users/...
inside your pods.
Recommended way
minikube mount /path/to/dir/to/mount:/vm-mount-path
is the recommended way to mount directories into minikube so that they can be used in your local Kubernetes cluster. The command works on all supported platforms.
See documentation and example: https://minikube.sigs.k8s.io/docs/tasks/mount/
I tried out aerokite's solution, but found out that I had to pass --mount
as well as --mount-string "local-path:minikube-path"
to mount a directory in minikube.
minikube start --mount-string ${HOME}/go/src/github.com/nginx:/data --mount
.
Spent some time figuring this out.
You can't mount your local directory into your Pod directly.
First, you need to mount your directory $HOME/go/src/github.com/nginx
into your minikube.
$ minikube start --mount-string="$HOME/go/src/github.com/nginx:/data" --mount
Then If you mount /data
into your Pod using hostPath, you will get you local directory data into Pod.
There is another way
Host's $HOME
directory gets mounted into minikube's /hosthome
directory. Here you will get your data
$ ls -la /hosthome/go/src/github.com/nginx
So to mount this directory, you can change your Pod's hostPath
hostPath:
path: /hosthome/go/src/github.com/nginx
