[SOLVED] How do I use the local directory as a persistent volume in k3d?

How do I use the local directory as a persistent volume in k3d?

I am using k3d to run local Kubernetes and created a cluster using k3d.

Now I want to mount a local directory as a persistent volume.

I know in minikube you can do:

$ 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 your local directory data into Pod.

Is there any similar technique in k3d?

Solution

According to the answers to this Github question the feature you're looking for is not available yet.

Here is some idea from this link:

The simplest I guess would be to have a pretty generic mount containing all the code, e.g. in my case, I could do k3d cluster create -v "$HOME/git:/git@agent:*" to get all the repositories on my host present in all agent nodes to be used for hot-reloading.

According to this documentation one can use the following command with the adequate flag:

k3d cluster create NAME -v [SOURCE:]DEST[@NODEFILTER[;NODEFILTER...]]

This command mounts volumes into the nodes

(Format:[SOURCE:]DEST[@NODEFILTER[;NODEFILTER...]]

Example:

`k3d cluster create --agents 2 -v /my/path@agent:0,1 -v /tmp/test:/tmp/other@server:0`

Here is also an interesting article how volumes and storage work in a K3s cluster (with examples).
