The everest add-on contains the following containers. You can adjust the specifications as required.
- **everest-csi-controller**: A Deployment workload. This container is responsible for creating, deleting, snapshotting, expanding, attaching, and detaching volumes. If the cluster version is 1.19 or later, the pod of the everest-csi-driver component also has an everest-localvolume-manager container by default. This container manages the creation of LVM storage pools and local PVs on the node.

- If the number of pods and PVCs is less than 2000, set the memory upper limit to 600 MiB.
- If the number of pods and PVCs is less than 5000, set the memory upper limit to 1 GiB.
- **everest-csi-driver**: A DaemonSet workload. This container is responsible for mounting and unmounting PVs and resizing file systems. If the region where the cluster is located supports node-attacher, the pod of the everest-csi-driver component also contains an everest-node-attacher container. This container is responsible for distributed EVS attaching. This configuration item is available in some regions.

The preceding three parameters are associated with each other and are constrained by the underlying storage resources in the region where the cluster is located. If you want to mount a large number of volumes (more than 500 EVS volumes per minute), you can contact the customer service personnel and configure the parameters under their guidance to prevent the everest add-on from running abnormally due to improper parameter settings.
Other parameters
- **cluster_id**: cluster ID
- **default_vpc_id**: ID of the VPC to which the data warehouse cluster belongs
- **disable_auto_mount_secret**: indicates whether the default AK/SK can be used when an object bucket or parallel file system is mounted. The default value is **false**.
- **enable_node_attacher**: indicates whether to enable the attacher on the agent to process the `VolumeAttachment <https://kubernetes.io/docs/reference/kubernetes-api/config-and-storage-resources/volume-attachment-v1/>`__.
- **flow_control**: This parameter is left blank by default.
- **over_subscription**: overcommitment ratio of the local storage pool (**local_storage**). The default value is **80**. If the size of the local storage pool is 100 GB, you can overcommit 180 GB.
- **project_id**: ID of the project to which the cluster belongs.
