MinIO Operator

MinIO is a Kubernetes-native high performance object store with an S3-compatible API. The MinIO Kubernetes Operator supports deploying MinIO Tenants onto private and public cloud infrastructures ("Hybrid" Cloud).

Procedure

1) Verify installation the MinIO Operator

Run the following command to verify the status of the Operator:

kubectl get pods -n minio-operator

The output resembles the following:

NAME                              READY   STATUS    RESTARTS   AGE
console-6b6cf8946c-9cj25          1/1     Running   0          99s
minio-operator-69fd675557-lsrqg   1/1     Running   0          99s

The console-* pod runs the MinIO Operator Console, a graphical user interface for creating and managing MinIO Tenants.

The minio-operator-* pod runs the MinIO Operator itself.

2) Access the Operator Console

Get the service-account token to access the UI:

kubectl -n minio-operator  get secret $(kubectl -n minio-operator get serviceaccount console-sa -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode

Run the following command to create a local proxy to the MinIO Operator Console:

kubectl -n minio-operator port-forward svc/console 9090

Open your browser to http://localhost:9090 and use the JWT token to log in to the Operator Console.

Click + Create Tenant to open the Tenant Creation workflow.

3) Build the Tenant Configuration

The Operator Console Create New Tenant walkthrough builds out a MinIO Tenant. The following list describes the basic configuration sections.

Name - Specify the Name, Namespace, and Storage Class for the new Tenant.

The Storage Class must correspond to a Storage Class that corresponds to Local Persistent Volumes that can support the MinIO Tenant.

The Namespace must correspond to an existing Namespace that does not contain any other MinIO Tenant.

Enable Advanced Mode to access additional advanced configuration options.
Tenant Size - Specify the Number of Servers, Number of Drives per Server, and Total Size of the Tenant.

The Resource Allocation section summarizes the Tenant configuration based on the inputs above.

Additional configuration inputs may be visible if Advanced Mode was enabled in the previous step.
Preview Configuration - summarizes the details of the new Tenant.

After configuring the Tenant to your requirements, click Create to create the new tenant.

The Operator Console displays credentials for connecting to the MinIO Tenant. You must download and secure these credentials at this stage. You cannot trivially retrieve these credentials later.

You can monitor Tenant creation from the Operator Console.
