MinIO ​

Let's see how to run MinIO (code) in a Kubernetes cluster.

Repository ​

We'll use the the official Helm chart:

bash
helm repo add minio https://charts.min.io/
helm repo update

Configuration ​

Create the values.yaml file to override default parameters.

yaml
resources:
  requests:
    memory: 512Mi
replicas: 1
mode: standalone
persistence:
  enabled: false
# access key length should be at least 3 character long
rootUser: admin
# secret key length should be at least 8 character long
rootPassword: pasWd8char
yaml
persistence:
  enabled: true
  size: 10Gi
yaml
ingress:
  enabled: true
  ingressClassName: nginx
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
  hosts:
    - minio.somedomain
  tls:
    - secretName: minio-tls
      hosts:
        - minio.somedomain
consoleIngress:
  enabled: true
  ingressClassName: nginx
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
  hosts:
    - minio-console.somedomain
  tls:
    - secretName: minio-console-tls
      hosts:
        - minio-console.somedomain

Deployment ​

Install the application:

bash
helm upgrade --install minio minio/minio -f values.yaml --namespace minio --create-namespace

Clean-up ​

Uninstall the application and delete the namespace:

bash
helm uninstall minio -n minio
kubectl delete ns minio
