[Minio] Install MinIO on Kubernetes through minio-operator

GIờ mình cần cài minio cho argo workflows lưu log.

Reference Links:
https://docs.min.io/minio/k8s/reference/minio-kubectl-plugin.html#kubectl-minio-init
https://thenewstack.io/how-minio-brings-object-storage-service-to-kubernetes/

trước tiên bạn cần lên đây để tìm các release mới nhất:
https://github.com/minio/operator/releases

mkdir minio-operator
cd minio-operator
wget https://github.com/minio/operator/releases/download/v4.3.9/kubectl-minio_4.3.9_linux_amd64 -O kubectl-minio
chmod +x kubectl-minio
mv kubectl-minio /usr/local/bin/
kubectl minio version

kubectl create ns minio-operator
kubectl minio init --output > minio-v4.3.9.yaml

sau khi deploy thành công thì chúng ta mở UI lên

Bạn sài cmd dưới này để lấy token

kubectl minio proxy

kubectl minio tenant create argo-workflows \
--servers 1 \
--volumes 4 \
--capacity 1Gi \
--namespace argo \
--storage-class longhorn-normal

root@work-space-u20:~/minio-operator# kubectl minio tenant create argo-workflows --servers 1 --volumes 4 --capacity 1Gi --namespace argo --storage-class longhorn-normal

Tenant 'argo-workflows' created in 'argo' Namespace

  Username: admin 
  Password: d78db831-0e8b-4d05-8aa6-b763eb0eba0a 
  Note: Copy the credentials to a secure location. MinIO will not display these again.

Ở trên namespace argo nó tạo 1 đống secret

tác giả cũng có nói:
Creating a tenant results in provisioning the PV and PVCs and deploying a statefulset. Since we mentioned the maximum capacity for the tenant as 1GiB spread across four volumes, MinIO created 4 PVs, 4 PVCs, and one statefulset.
