This PR introduces MinIO object storage deployment in a Kubernetes cluster.

Current setup:

  • The storage class is local-storage that requires node affinity, hence a node name and an existing path on it.
  • The MinIO service is exposed by a custom IP (i.e., ClusterIP publishing type) that is specified in service.yaml

Prerequisites

Modify the YAML config of the MinIO service

The only type of storage that is supported is local storage (at least for now).

Set up the MinIO service (after the cluster is up and running):

# create a folder in the local storage (on <MINIO_NODE_NAME> that is one of the Kubernetes nodes)
sudo mkdir -p <MINIO_PATH>

cd ./configs/storage/minio

# create a persistent volume (PV) and the corresponding PV claim
# specify the node name that would host the MinIO objects
# (use `hostname` command for the local node)
MINIO_NODE_NAME=<MINIO_NODE_NAME> MINIO_PATH=<MINIO_PATH> envsubst < pv.yaml | kubectl apply -f -
kubectl apply -f pv-claim.yaml
# create a storage app and the corresponding service
kubectl apply -f deployment.yaml
kubectl apply -f service.yaml

How to check if MinIO is ready

Check if a minio-* pod is in the Running state with kubectl get pods

Using the MinIO client

An example of how the service can be accessed, using the MinIO client ("minio" is the access key, "minio123" is the secret key):

mc alias set myminio http://10.96.0.46:9000 minio minio123
mc mb myminio/mybucket
mc cp README.md myminio/mybucket/tmp

Cleanup procedure

Note that files in the bucket are persistent in the local filesystem despite persistent volume removal.

kubectl delete deployment minio-deployment
kubectl delete pvc minio-pv-claim
kubectl delete svc minio-service
kubectl delete pv minio-pv

Looks good to me, if you've tested it and it works then I'll go ahead and benchmark vHive storage transfer next.
