In a typical modern infrastructure deployment, application, database, key-store, etc. already live in containers and are managed by orchestration platforms. MinIO brings robust, scalable, AWS S3 compatible object storage to the lot.

package cmd

import (
	"net/http"

	"github.com/minio/mux"
)

const (
	healthCheckPath            = "/health"
	healthCheckLivenessPath    = "/live"
	healthCheckReadinessPath   = "/ready"
	healthCheckClusterPath     = "/cluster"
	healthCheckClusterReadPath = "/cluster/read"
	healthCheckPathPrefix      = minioReservedBucketPath + healthCheckPath
)

MinIO server has two healthcheck related un-authenticated endpoints, a liveness probe to indicate if server is responding, cluster probe to check if server can be taken down for maintenance.

- Liveness probe available at `/minio/health/live`
- Cluster probe available at `/minio/health/cluster`

Read more on how to use these endpoints in [MinIO healthcheck guide](https://github.com/minio/minio/blob/master/docs/metrics/healthcheck/README.md).

## Prometheus Probe

Further, the temp. S3 credentials will never out-live the client certificate. For example, if the `MINIO_IDENTITY_TLS_STS_EXPIRY` is 7 days but the certificate itself is only valid for the next 3 days, then MinIO will return S3 credentials that are valid for 3 days only.

## Caveat

## 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
    scheme: HTTP
  initialDelaySeconds: 120

MinIO on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation. Upgrading the Chart ---------- You can use Helm to update MinIO version in a live release. Assuming your release is named as `my-release`, get the values using the command: ```bash helm get values my-release > old_values.yaml ``` Then change the field `image.tag` in `old_values.yaml` file with MinIO image tag you want to use.
