1) Install the MinIO Kubernetes Plugin

The MinIO Kubernetes Plugin provides a command for initializing the MinIO Operator.

2) Initialize the MinIO Kubernetes Operator

Run the kubectl minio init command to initialize the MinIO Operator:

kubectl minio init

The command initializes the MinIO Operator with the following default settings:

  • Deploy the Operator into the minio-operator namespace. Specify the kubectl minio init --namespace argument to deploy the operator into a different namespace.
  • Use cluster.local as the cluster domain when configuring the DNS hostname of the operator. Specify the kubectl minio init --cluster-domain argument to set a different cluster domain <tasks/administer-cluster/dns-custom-nameservers/> value.

The Operator deploys with certain default settings and resource requests. To modify these settings, do the following:

  1. Append the kubectl minio init -o > operator.yaml to save the YAML configuration to file
  2. Modify settings as-needed to fit your deployment
  3. Run kubectl apply -f operator.yaml to apply the customized Operator deployment.

Important

Document all arguments used when initializing the MinIO Operator.

3) Validate the Operator Installation

To verify the installation, run the following command:

kubectl get all --namespace minio-operator

If you initialized the Operator with a custom namespace, replace minio-operator with that namespace.

The output resembles the following:
