For example, you can configure STS with Client Grants (KeyCloak) using the guides at [MinIO STS Quickstart Guide](https://docs.min.io/community/minio-object-store/developers/security-token-service.html) and [KeyCloak Configuration Guide](https://github.com/minio/minio/blob/master/docs/sts/keycloak.md). Once this is done, STS credentials can be generated:

```

	pluginAuthnServiceLastSuccSecondsMD      = NewCounterMD(pluginAuthnServiceLastSuccSeconds, "When plugin authentication is configured, returns time (in seconds) since the last successful request to the service")

OPA is enabled through MinIO's Access Management Plugin feature.

## Get started

### 1. Start OPA in a container

```sh
podman run -it \
    --name opa \
    --publish 8181:8181 \

### 4. Update `scrape_configs` section in prometheus.yml

To authorize every scrape request, copy and paste the generated `scrape_configs` section in the prometheus.yml and restart the Prometheus service.

### 5. Start Prometheus

Start (or) Restart Prometheus service by running

```sh
./prometheus --config.file=prometheus.yml
```
