What is Minio?

MinIO's High Performance Object Storage is Open Source, Amazon S3 compatible, Kubernetes Native and is designed for cloud native workloads like AI.

Deploying Minio on OpenShift

1. Create PVC to persist Minio data

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: minio-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 50Gi
  volumeMode: Filesystem

2. Create Secret to secure minio credentials

kind: Secret
apiVersion: v1
metadata:
  name: minio-secret
stringData:
  minio_root_user: <your_secure_user>
  minio_root_password: <your_secure_password>

3. Create Deployment to deploy your minio instance

kind: Deployment
apiVersion: apps/v1
metadata:
  name: minio
spec:
  replicas: 1
  selector:
    matchLabels:
      app: minio
  template:
    metadata:
      labels:
        app: minio
    spec:
      containers:
        - name: minio
          env:
            - name: MINIO_ROOT_USER
              valueFrom:
                secretKeyRef:
                  name: minio-secret
                  key: minio_root_user
            - name: MINIO_ROOT_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: minio-secret
                  key: minio_root_password
          ports:
            - containerPort: 9000
              protocol: TCP
            - containerPort: 9090
              protocol: TCP
          volumeMounts:
            - name: data
              mountPath: /data
              subPath: minio
          image: >-
            quay.io/minio/minio:RELEASE.2023-06-19T19-52-50Z
          args:
            - server
            - /data
            - --console-address
            - :9090
      volumes:
        - name: data
          persistentVolumeClaim:
            claimName: minio-pvc

4. Create Service to expose minio to the cluster network

kind: Service
apiVersion: v1
metadata:
  name: minio-service
spec:
  ports:
    - name: api
      protocol: TCP
      port: 9000
      targetPort: 9000
    - name: ui
      protocol: TCP
      port: 9090
      targetPort: 9090
  type: ClusterIP
  selector:
    app: minio

5. Create Routes to expose your service/application to external traffic

kind: Route
apiVersion: route.openshift.io/v1
metadata:
  name: minio-api
spec:
  to:
    kind: Service
    name: minio-service
    weight: 100
  port:
    targetPort: api
  tls:
    termination: edge
    insecureEdgeTerminationPolicy: Redirect
---
kind: Route
apiVersion: route.openshift.io/v1
metadata:
  name: minio-ui
spec:
  to:
    kind: Service
    name: minio-service
    weight: 100
  port:
    targetPort: ui
  tls:
    termination: edge
    insecureEdgeTerminationPolicy: Redirect
