veFaaS supports mounting FileNAS so that you can store data in FileNAS file systems. This topic describes how to mount FileNAS.
Background information
veFaaS is seamlessly integrated with FileNAS. You can configure FileNAS for functions. FileNAS mount settings include the FileNAS filesystem, mount target, remote directory, local directory, and more. After the FileNAS configuration is successful, functions can manage the remote FileNAS filesystem by accessing the local directory mapped to the FileNAS mount target. The advantages of mounting FileNAS as storage for veFaaS functions are as follows:
- Temporary files generated by veFaaS can be persisted to FileNAS, and the size of temporary files is not limited by the local disk space of a function instance.
- Multiple functions can share a single FileNAS file system to enable file sharing.
tip
The fees incurred for storing data in FileNAS are charged by FileNAS. For details, see FileNAS billing.
Prerequisites
- VPC
- You have activated Volcano Engine VPC.
- A VPC, subnets, and security groups have been created in the region for function deployment. For details, see Creating VPCs, Creating subnets, and Creating security groups.
- NAS file storage
- You have activated Volcano Engine FileNAS.
- A FileNAS filesystem has been created in the region where the function is to be deployed. For details, see Creating filesystems.
- A mount target has been created in the VPC. For details, see Creating mount targets.
Limits
- FileNAS supports adding mount targets only in VPC. Therefore, functions must have VPC access enabled and be configured to use the same VPC network as the mount target.
- A function supports up to 10 FileNAS file systems.
- When a single function is configured to use multiple FileNAS file systems, file systems and remote directories can be duplicated, but local directories cannot be duplicated.
- If a function mounts both FileNAS and TOS, the local directories set for FileNAS and TOS mount targets cannot be duplicated.
- The default user and user group for the FileNAS directory mounted to a function are as follows and cannot be modified.
- For a non-Native function, both the UserID and the GroupID are 1000.
- For a Native function, both the UserID and the GroupID are root.
Procedure
- You can configure a FileNAS file system for a function using one of the following methods:
- During function creation
- When you create the function, in the Advanced settings section, enable VPC access and then configure FileNAS mounting. For detailed steps of creating functions, see Creating functions.
- After function creation
- Log in to the veFaaS console, and in the top navigation bar, select the region where your funtion is located.
- In the function list, click the name of the function to enter the Function settings page.
- On the function settings page, enable VPC access and configure FileNAS mounting.
- Configure the VPC and FileNAS mount parameters and save the configuration.
- ParameterDescriptionVPC accessEnable VPC access and configure the target VPC, subnet, and security groups.tipThe VPC of the function must match the VPC of the FileNAS mount target. Subnet and availability zone settings have no such restrictions. However, to achieve optimal performance, we recommend keeping the FileNAS mount target subnet and the VPC subnet for the function in the same availability zone.NAS mountingEnable FileNAS mounting and add the target FileNAS filesystems. Click the + icon to add a filesystem. Up to 10 filesystems can be added. For each FileNAS filesystem, configure the following items:
- Filesystem: Select the FileNAS filesystem to mount. Both Extreme FileNAS and Capacity FileNAS filesystems are supported.
- Mount point: Select a FileNAS mount target that matches the VPC configured for the current function.
- Remote directory: Specify the directory of the FileNAS filesystem that the function needs to access. The remote directory must start with /. If the specified directory does not exist in the remote FileNAS filesystem, veFaaS will automatically create the directory.
- Local directory: Configure the local directory in the function runtime environment. The local directory must start with /. Do not enter /tmp, /opt/bytefaas, or /opt/tiger/bytefaas/binary.
tipThe remote directory in the FileNAS filesystem maps to the local directory in the local file system. For example, if the local directory is /localPath and the remote directory is /demo, the function can access the remote directory <mount target domain>:/<fsid>/demo by accessing the local directory /localPath.

What to do next
For the storage configuration to take effect, you need to release the function. For details, see Releasing functions.
