# MinIO Healthcheck

MinIO server exposes three un-authenticated, healthcheck endpoints liveness probe and a cluster probe at `/minio/health/live` and `/minio/health/cluster` respectively.

## Liveness probe

This probe always responds with '200 OK'. Only fails if 'etcd' is configured and unreachable. When liveness probe fails, Kubernetes like platforms restart the container.

```
livenessProbe:
  httpGet:
    path: /minio/health/live
    port: 9000

// credentials. It is for MinIO testing purposes only.
//
// Run like:
//
// $ MINIO_ENDPOINT=http://localhost:9000 go run gen-oidc-sts-cred.go

## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a

import (
	xhttp "github.com/minio/minio/internal/http"

const (
	// MetaMultipart indicates that the object has been uploaded
	// in multiple parts - via the S3 multipart API.
	MetaMultipart = "X-Minio-Internal-Encrypted-Multipart"

	// MetaIV is the random initialization vector (IV) used for
	// the MinIO-internal key derivation.
