Prerequisites

MinIO Kubernetes Operator and Plugin

This procedures on this page requires a valid installation of the MinIO Kubernetes Operator and assumes the local host has a matching installation of the MinIO Kubernetes Operator. This procedure assumes the latest stable Operator and Plugin version .

See deploy-operator-kubernetes for complete documentation on deploying the MinIO Operator.

Procedure (CLI)

This procedure documents upgrading pods running on a MinIO Tenant.

1) Validate the Active MinIO Version

Use the kubectl minio tenant info command to return a summary of the MinIO Tenant, including the new Pool:

kubectl minio tenant info TENANT_NAME \
  --namespace TENANT_NAMESPACE

Replace TENANT_NAME with the name of the Tenant.
Replace TENANT_NAMESPACE with the namespace of the Tenant.

The output includes the version of the MinIO Server used by all Pods in the Tenant.

2) Upgrade the MinIO Tenant

Use the kubectl minio tenant upgrade command to upgrade the container image used by all MinIO Pods in the Tenant. MinIO upgrades all minio server processes at once. This may result in downtime until the upgrade process completes.

kubectl minio tenant upgrade TENANT_NAME                      \
        --image     minio:minio:RELEASE:YYYY-MM-DDTHH-MM-SSZ  \
        --namespace TENANT_NAMESPACE

Replace TENANT_NAME with the name of the Tenant.
Replace RELEASE:YYYY-MM-DDTHH-MM-SSZ with the specific release to use. Specify minio/minio to use the latest stable version of MinIO.
Replace TENANT_NAMESPACE with the namespace of the Tenant.

See MinIO's DockerHub Repository for a list of available release tags.
