The information was collected from the endpoint or specific CR from the storage provider (e.g., ShareManager CR from Longhorn). + +## Architecture + +The **Network FS Manager** is a Kubernetes controller developed by Go and leverages Rancher's [wrangler](https://github.com/rancher/wrangler/) framework. + +**networkfs-manager** is a single binary built by Go and could be deployed as a Kubernetes DaemonSet. You can also install it as a Helm chart. + +The **Network FS Manager** mainly focuses on the CR `Endpoint` and `ShareManager` from Longhorn. And provides its own CR `Networkfilesystem` to store the network filesystem information. + +### `Networkfilesystem` Custom Resource(CR) + +The `Networkfilesystem` CR is used to store the corresponding network filesystem information. The CR structure is as follows: + + apiVersion: harvesterhci.io/v1beta1 + kind: NetworkFilesystem + metadata: + name: pvc-76d28565-fa65-4b37-962b-62da3ee668f8 + namespace: harvester-system + spec: + desiredState: Disabled + networkFSName: pvc-76d28565-fa65-4b37-962b-62da3ee668f8 + status: + conditions: + endpoint: "" + state: Disabled + status: NotReady + mountOptions: "" + type: NFS + + +The `desiredState` is used to control the state of the network filesystem. Usually `Enabled` or `Disabled`. The `networkFSName` is the name (usually path) of the network filesystem and is used for the mount path, like the entry point. The `state` is the state that the current state compares with the `desiredState`. The `status` is the status of the network filesystem. The `mountOptions` are the recommended mount options to hint the user to mount the network filesystem. The `type` is the type of the network filesystem. Now, only support `NFS`. + +## License +Copyright (c) 2024 [Rancher Labs, Inc.](http://rancher.com) + +Licensed under the Apache License, Version 2.0 (the "License"); +you may not use this file except in compliance with the License. +You may obtain a copy of the License at + +[http://www.apache.org/licenses/LICENSE-2.0](http://www.apache.org/licenses/LICENSE-2.0) + +Unless required by applicable law or agreed to in writing, software +distributed under the License is distributed on an "AS IS" BASIS, +WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +See the License for the specific language governing permissions and +limitations under the License. \ No newline at end of file
