local-volume-provisioner

Static provisioner of local volumes

Download this Image

The image is available on cgr.dev:

docker pull cgr.dev/chainguard/local-volume-provisioner:latest

Usage

To be able to test the local volume provisioner, you need to have a Kubernetes cluster running. You can use k3d to create a local cluster.

Create a local cluster

k3d create cluster

Deploy the local volume provisioner

# creates the necessary StorageClass
kubectl apply -f kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/sig-storage-local-static-provisioner/master/deployment/kubernetes/example/default_example_storageclass.yaml

# creates the local volume provisioner
kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/sig-storage-local-static-provisioner/master/deployment/kubernetes/example/default_example_provisioner_generated.yaml

# changes the provisioner image to the one you want to test
kubectl set image daemonset/local-volume-provisioner provisioner="cgr.dev/chainguard/local-volume-provisioner:latest"

Please ensure that the local volume provisioner is running before moving to the next step:

kubectl rollout status daemonset/local-volume-provisioner --timeout=120s

So, if everything is running, you should shell/exec into the nodes and do the following:

# Get server and worker node names from k3d, filtering by role
node_names=$(k3d node list -o json | jq -r '.[] | select(.role == "server" or .role == "agent") | .name')

# Loop over each node name and execute the commands
for node in $node_names; do
    echo "Configuring node: $node"

    # Create directory
    docker exec $node mkdir -p /mnt/fast-disks/vol1

    # Mount tmpfs
    docker exec $node mount -t tmpfs vol1 /mnt/fast-disks/vol1

    echo "Configuration complete for node: $node"
done

Once you have the local disks mounted, you should see the PVs created:

kubectl get pv

That's it! You have the local volume provisioner running and managing the local disks on your cluster.
