# Mount remote storage to container using compose file
|
||||||
|
|
||||||
|
*(https://oneuptime.com/blog/post/2025-12-15-how-to-use-nas-storage-with-docker-compose/view)*
|
||||||
|
|
||||||
|
There are 3 types of remote connections possible, NFS, CIFS and iSCSI.
|
||||||
|
|
||||||
|
In addition to having the containers connect directly to the remote storage, it is also possible to simply let the host mount a remote storage location to a local mount point and then point the container to this location on the local host.
|
||||||
|
|
||||||
|
## Quick Protocol Comparison
|
||||||
|
|
||||||
|
| Protocol | Best For | Strengths | Watch-outs |
|
||||||
|
|---|---|---|---|
|
||||||
|
| NFS | Linux hosts, shared access across containers | Simple setup, low overhead, native Docker support | No built-in encryption, UID/GID mapping can be tricky |
|
||||||
|
| SMB/CIFS | Windows hosts, mixed environments, AD integration | Works everywhere, credential-based auth | Higher overhead, requires cifs-utils on host |
|
||||||
|
| iSCSI | Containers that need block access to storage | | |
|
||||||
|
| Local mount + bind | Maximum performance, simple setups | No network latency, works offline | Requires NAS mounted on host first |
|
||||||
|
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
Before starting:
|
||||||
|
|
||||||
|
- Your NAS is reachable from your Docker host (same network or routed)
|
||||||
|
- You have created a share/export on your NAS
|
||||||
|
- Your Docker host has the required client packages
|
||||||
|
|
||||||
|
## Installing Required Packages
|
||||||
|
For NFS on Debian/Ubuntu:
|
||||||
|
|
||||||
|
The NFS client package allows your Docker host to mount NFS shares. This is a one-time setup required before Docker can create NFS volumes.
|
||||||
|
```
|
||||||
|
# Update package list and install NFS client utilities
|
||||||
|
# nfs-common includes mount.nfs required for NFS volume mounts
|
||||||
|
sudo apt-get update && sudo apt-get install -y nfs-common
|
||||||
|
```
|
||||||
|
|
||||||
|
For NFS on RHEL/Rocky/AlmaLinux:
|
||||||
|
|
||||||
|
```
|
||||||
|
# Install NFS utilities for Red Hat-based distributions
|
||||||
|
# Includes rpcbind and other NFS dependencies
|
||||||
|
sudo dnf install -y nfs-utils
|
||||||
|
```
|
||||||
|
|
||||||
|
For SMB/CIFS:
|
||||||
|
|
||||||
|
CIFS utilities are required when connecting to Windows shares or NAS devices configured for SMB protocol.
|
||||||
|
|
||||||
|
```
|
||||||
|
# Debian/Ubuntu - install CIFS mount utilities
|
||||||
|
sudo apt-get install -y cifs-utils
|
||||||
|
|
||||||
|
# RHEL/Rocky - same package, different package manager
|
||||||
|
sudo dnf install -y cifs-utils
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## NFS
|
||||||
|
|
||||||
|
This Docker Compose configuration demonstrates how to declare an NFS volume using the built-in local driver with NFS options. The volume is mounted into the container just like any other Docker volume.
|
||||||
|
|
||||||
|
Example 1:
|
||||||
|
```
|
||||||
|
# docker-compose.yml
|
||||||
|
version: "3.8"
|
||||||
|
|
||||||
|
services:
|
||||||
|
app:
|
||||||
|
image: nginx:alpine
|
||||||
|
volumes:
|
||||||
|
# Mount the NFS volume to serve static files
|
||||||
|
- nfs-data:/usr/share/nginx/html
|
||||||
|
ports:
|
||||||
|
- "8080:80"
|
||||||
|
|
||||||
|
# Volume definitions - NFS configuration lives here
|
||||||
|
volumes:
|
||||||
|
nfs-data:
|
||||||
|
# Use the local driver with NFS-specific options
|
||||||
|
driver: local
|
||||||
|
driver_opts:
|
||||||
|
# Specify NFS as the filesystem type
|
||||||
|
type: nfs
|
||||||
|
# Mount options: NAS IP, NFS version, and behavior flags
|
||||||
|
# soft = return errors on timeout, nolock = disable file locking
|
||||||
|
o: addr=192.168.1.100,nfsvers=4.1,soft,nolock
|
||||||
|
# NFS export path on your NAS (note the leading colon)
|
||||||
|
device: ":/volume1/docker-data"
|
||||||
|
```
|
||||||
|
|
||||||
|
Example 2:
|
||||||
|
```
|
||||||
|
volumes:
|
||||||
|
# Database volume: use 'hard' mount for data integrity
|
||||||
|
# 'hard' = retry indefinitely on failure (prevents data corruption)
|
||||||
|
# 'intr' = allow interrupt to prevent hung processes
|
||||||
|
postgres-data:
|
||||||
|
driver: local
|
||||||
|
driver_opts:
|
||||||
|
type: nfs
|
||||||
|
o: addr=192.168.1.100,nfsvers=4.1,hard,intr
|
||||||
|
device: ":/volume1/docker/postgres"
|
||||||
|
```
|
||||||
|
|
||||||
|
### NFS Mount Options Explained
|
||||||
|
| Option | Purpose |
|
||||||
|
|---|---|
|
||||||
|
| addr= | NAS IP address |
|
||||||
|
| nfsvers=4.1 | NFS version (use 4.1 or 4.2 for best compatibility) |
|
||||||
|
| soft | Return errors on timeout instead of hanging (use hard for databases) |
|
||||||
|
| nolock | Disable file locking (faster, but don't use for databases) |
|
||||||
|
| rw | Read-write mount (default) |
|
||||||
|
| noatime | Don't update access times (better performance) |
|
||||||
|
|
||||||
|
## CIFS
|
||||||
|
For Windows environments or when your NAS only offers SMB shares.
|
||||||
|
|
||||||
|
### Basic SMB Volume
|
||||||
|
|
||||||
|
```
|
||||||
|
version: "3.8"
|
||||||
|
|
||||||
|
services:
|
||||||
|
app:
|
||||||
|
image: nginx:alpine
|
||||||
|
volumes:
|
||||||
|
- smb-data:/usr/share/nginx/html
|
||||||
|
|
||||||
|
volumes:
|
||||||
|
smb-data:
|
||||||
|
driver: local
|
||||||
|
driver_opts:
|
||||||
|
type: cifs
|
||||||
|
o: addr=192.168.1.100,username=myuser,password=mypassword,file_mode=0777,dir_mode=0777
|
||||||
|
device: "//192.168.1.100/docker-data"
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
### SMB with Credentials File (More Secure)
|
||||||
|
Storing passwords in docker-compose.yml is a bad idea. Use a credentials file instead:
|
||||||
|
|
||||||
|
```
|
||||||
|
# Create credentials file on Docker host
|
||||||
|
sudo nano /etc/docker-smb-credentials
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
username=myuser
|
||||||
|
password=mypassword
|
||||||
|
domain=WORKGROUP
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo chmod 600 /etc/docker-smb-credentials
|
||||||
|
```
|
||||||
|
|
||||||
|
```
|
||||||
|
version: "3.8"
|
||||||
|
|
||||||
|
services:
|
||||||
|
app:
|
||||||
|
image: nginx:alpine
|
||||||
|
volumes:
|
||||||
|
- smb-data:/usr/share/nginx/html
|
||||||
|
|
||||||
|
volumes:
|
||||||
|
smb-data:
|
||||||
|
driver: local
|
||||||
|
driver_opts:
|
||||||
|
type: cifs
|
||||||
|
o: addr=192.168.1.100,credentials=/etc/docker-smb-credentials,uid=1000,gid=1000,file_mode=0644,dir_mode=0755
|
||||||
|
device: "//192.168.1.100/docker-data"
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
### SMB Mount Options
|
||||||
|
|
||||||
|
| Option | Purpose |
|
||||||
|
|---|---|
|
||||||
|
| credentials= | Path to credentials file |
|
||||||
|
| uid= / gid= | Map files to specific user/group ID |
|
||||||
|
| file_mode= / dir_mode= | Set permissions for files/directories |
|
||||||
|
| vers=3.0 | SMB protocol version (try 2.1 or 3.0) |
|
||||||
|
| seal | Enable encryption (SMB 3.0+) |
|
||||||
|
|
||||||
|
