This example assumes a local Spark installation. +See the [Spark Notebooks Example](../spark/README.md) for a more advanced Spark setup. + +## Starting the Example + +Before starting the Ceph + Polaris stack, you’ll need to configure environment variables that define network settings, credentials, and cluster IDs. + +Copy the example environment file: +```shell +mv getting-started/ceph/.env.example getting-started/ceph/.env +``` + +The services are started **in sequence**: +1. Monitor + Manager +2. OSD +3. RGW +4. Polaris + +Note: this example pulls the `apache/polaris:latest` image, but assumes the image is `1.2.0-incubating` or later. + + +### 1.
