This guide will walk you through configuring and mounting an NFS file share to a Coder workspace. The NFS file share will be separate from the user's persistent volume (represented as /home/<user> in the workspace).

Requirements

To mount an NFS file share, you must use a container-based virtual machine (CVM) workspace with a FUSE device attached. You can enable both of these features in the admin panel by navigating to Manage > Admin > Infrastructure > Workspace container runtime.

Please review the CVM infrastructure requirements before enabling CVMs and FUSE devices.

The Coder workspace must have either nfs-utils or nfs-common installed.

The server must have either nfs-utils or nfs-kernel-server installed.

Ensure that no firewalls are blocking the client connections. By default, the NFS daemon is configured to run on a static port of 2049.

Server configuration steps

1. Create an NFS mount on the server for the clients to access:

   export NFS_MNT_PATH=/mnt/nfs_share
   # Create directory to shaare
   sudo mkdir -p $NFS_MNT_PATH
   # Assign UID & GIDs access
   sudo chown -R uid:gid $NFS_MNT_PATH
   sudo chmod 777 $NFS_MNT_PATH
   

2. Grant access to the clients by updating the /etc/exports file, which controls the directories shared with remote clients. See Red Hat's docs for more information about the configuration options.

   # Provides read/write access to clients accessing the NFS from any IP address.
   /mnt/nfs_share  *(rw,sync,no_subtree_check)
   

3. Export the NFS file share directory. You must do this every time you change /etc/exports.

   sudo exportfs -a
   sudo systemctl restart <nfs-package>
   

Client (Coder workspace) configuration steps

1. Create a directory where the NFS mount will reside:

   sudo mkdir -p /mnt/nfs_clientshare
   

2. Mount the NFS file share from the server into your workspace:

   sudo mount <server-IP>:/mnt/nfs_share /mnt/nfs_clientshare
