# MinIO Multi-Tenant Deployment Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io) [![Docker Pulls](https://img.shields.io/docker/pulls/minio/minio.svg?maxAge=604800)](https://hub.docker.com/r/minio/minio/)

This topic provides commands to set up different configurations of hosts, nodes, and drives. The examples provided here can be used as a starting point for other configurations.

1. [Standalone Deployment](#standalone-deployment)

MinIO is a high performance distributed object storage server, designed for large-scale private cloud infrastructure. MinIO is designed in a cloud-native manner to scale sustainably in multi-tenant environments. Orchestration platforms like Kubernetes provide perfect cloud-native environment to deploy and scale MinIO.

## MinIO Deployment on Kubernetes

There are multiple options to deploy MinIO on Kubernetes:

MinIO is built ground up on the cloud-native premise. With features like erasure-coding, distributed and shared setup, it focuses only on storage and does it very well. While, it can be scaled by just replicating MinIO instances per tenant via an orchestration platform.

// error returned by IAM when a use a builtin IDP command when they could mean
// to use a LDAP command.
var errNoSuchUserLDAPWarn = errors.New("Specified user does not exist. If you meant a user in LDAP please use command under `mc idp ldap`")

// error returned when service account is not found
var errNoSuchServiceAccount = errors.New("Specified service account does not exist")

# MinIO Server Limits Per Tenant

For optimal production setup MinIO recommends Linux kernel version 4.x and later.

### Understanding JWT Claims

> NOTE: JWT claims are only meant for WebIdentity and ClientGrants.
> AssumeRole or LDAP users can skip the entire portion and directly visit one of the links below.

- On Operator based MinIO deployments, you need to modify the `tenant.yaml` specification and modify the `pools:` section from two entries to a single entry. After making relevant changes, proceed to execute `kubectl apply -f tenant.yaml`.

> Without a 'Complete' status any 'Active' or 'Draining' pool(s) are not allowed to be removed once configured.

	config, updatedAt, err := globalBucketMetadataSys.GetLifecycleConfig(bucket)
	if err != nil {
		writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}
	// explicitly set ExpiryUpdatedAt nil as its meant for internal consumption only
	config.ExpiryUpdatedAt = nil

	configData, err := xml.Marshal(config)
	if err != nil {
		writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}

	region := globalSite.Region
	for targetID, target := range evnot.targetList.TargetMap() {
		// httpclient target is part of ListenNotification
		// which doesn't need to be listed as part of the ARN list
		// This list is only meant for external targets, filter
		// this out pro-actively.
		if !strings.HasPrefix(targetID.ID, "httpclient+") {
			if onlyActive {
				if _, err := target.IsActive(); err != nil {
					continue
