Your Debian Docker host should read/write storage on TrueNAS.

Choose SMB or NFS

• SMB: easiest, especially if Windows clients also use the same shares
• NFS: great Linux permissions/performance

This page shows SMB (simple) plus NFS notes.

Option A: SMB mounts

1) Install cifs-utils

sudo apt update
sudo apt install -y cifs-utils

2) Create mount points

sudo mkdir -p /mnt/nas/media
sudo mkdir -p /mnt/nas/photos
sudo mkdir -p /mnt/nas/documents
sudo mkdir -p /mnt/nas/backups

3) Create credentials file

sudo nano /etc/samba/credentials-truenas

username=smbuser
password=YOUR_PASSWORD_HERE
domain=WORKGROUP

Secure it:

sudo chmod 600 /etc/samba/credentials-truenas

4) Add fstab entries

sudo nano /etc/fstab

Example (adjust share names + IP):

//<TRUENAS-IP>/media      /mnt/nas/media      cifs  credentials=/etc/samba/credentials-truenas,uid=1000,gid=1000,iocharset=utf8,file_mode=0775,dir_mode=0775,nofail  0  0
//<TRUENAS-IP>/photos     /mnt/nas/photos     cifs  credentials=/etc/samba/credentials-truenas,uid=1000,gid=1000,iocharset=utf8,file_mode=0775,dir_mode=0775,nofail  0  0
//<TRUENAS-IP>/documents  /mnt/nas/documents  cifs  credentials=/etc/samba/credentials-truenas,uid=1000,gid=1000,iocharset=utf8,file_mode=0770,dir_mode=0770,nofail  0  0
//<TRUENAS-IP>/backups    /mnt/nas/backups    cifs  credentials=/etc/samba/credentials-truenas,uid=1000,gid=1000,iocharset=utf8,file_mode=0770,dir_mode=0770,nofail  0  0

Mount:

sudo mount -a

Verify:

df -h | grep /mnt/nas

Option B: NFS notes

If you prefer NFS:

1. Enable NFS service on TrueNAS
2. Export datasets
3. Mount with nfs4 in /etc/fstab
