Unraid XML Generator
Core Pattern
The key insight for Unraid Docker templates:
xml
<Container version="2">
<Name>mycontainer</Name>
<Repository>image:tag</Repository>
<Network>bridge</Network>
<!-- KEY: override ENTRYPOINT to /bin/sh -->
<ExtraParams>--entrypoint /bin/sh</ExtraParams>
<!-- KEY: pass real startup command through shell -ec -->
<PostArgs>-ec 'real startup command here'</PostArgs>
<!-- User-configurable variables -->
<Config Name="Display Name" Target="ENV_VAR" Default="..." Type="Variable" Display="always" Required="false" Mask="true">default_value</Config>
<Config Name="Port" Target="PORT" Default="8080" Mode="tcp" Type="Port" Display="always" Required="true">8080</Config>
<Config Name="Data Path" Target="/data" Default="/mnt/user/appdata/mycontainer" Mode="rw" Type="Path" Display="always" Required="true">/mnt/user/appdata/mycontainer</Config>
</Container>
Template Field Reference
| Field | Purpose |
|---|---|
<Name> | Unique container identifier |
<Repository> | Docker image with tag |
<Registry> | Registry URL (optional, informational) |
<Network> | Network mode: bridge, host, none |
<Shell> | Default shell (bash / sh) |
<ExtraParams> | Extra docker run flags (e.g. --entrypoint /bin/sh) |
<PostArgs> | Startup command passed to shell -ec |
<WebUI> | Format: http://[IP]:[PORT:nnnn]/ — shows button in Unraid UI |
<Icon> | URL to icon image |
<Category> | Unraid category string |
<Config> | User-configurable parameter |
Config Types
| Type | Example |
|---|---|
Variable | Environment variable (Target = env var name) |
Port | Port mapping (Mode="tcp"/"udp") |
Path | Volume path (Mode="rw"/"ro") |
Slider | Numeric slider (requires Min, Max, Step) |
Description | Read-only description text |
Config Display Options
| Display value | When shown |
|---|---|
always | Always visible in UI |
advanced | Hidden behind "Advanced" toggle |
hidden | Never shown (manual config) |
Masked Variables (secrets)
Set Mask="true" on Type="Variable" Config entries to:
- Hide the value from the UI (shown as
••••••) - Treat as sensitive (API keys, tokens, passwords)
PostArgs Shell Pattern
bash
# Correct way to write PostArgs in XML:
<PostArgs>-ec 'export VAR1="value1" && export VAR2="value2" && exec real_command --flag arg'</PostArgs>
# Breaking down:
# -e : exit on error
# -c : read command from string (not stdin)
# '...' : single-quoted command string
Standard Config Variables to Include
For any container:
xml
<Config Name="HTTP Proxy" Target="HTTP_PROXY" Default="" Type="Variable" Display="advanced" Required="false" Mask="false">http://192.168.8.30:7893</Config>
<Config Name="HTTPS Proxy" Target="HTTPS_PROXY" Default="" Type="Variable" Display="advanced" Required="false" Mask="false">http://192.168.8.30:7893</Config>
<Config Name="NO Proxy" Target="NO_PROXY" Default="" Type="Variable" Display="advanced" Required="false" Mask="false">localhost,127.0.0.1,192.168.0.0/16</Config>
<Config Name="TZ" Target="TZ" Default="Asia/Shanghai" Type="Variable" Display="advanced" Required="false" Mask="false">Asia/Shanghai</Config>
Script Usage
bash
python3 scripts/generate_template.py \
--name opencode \
--image ghcr.io/anomalyco/opencode:latest \
--port 4096 \
--web-port 4097 \
--output /tmp/opencode.xml
# Generate with all standard env vars:
python3 scripts/generate_template.py \
--name opencode \
--image ghcr.io/anomalyco/opencode:latest \
--port 4096 \
--web-port 4097 \
--proxy 192.168.8.30:7893 \
--tz Asia/Shanghai \
--output /tmp/opencode.xml
Common Pitfalls
- Double quotes in PostArgs → escape as
"in XML - ENTRYPOINT bypass → always use
<ExtraParams>--entrypoint /bin/sh</ExtraParams> - Shell variable substitution → use single quotes for PostArgs to prevent
$VARexpansion by XML parser - Template filename → must start with
my-and end with.xml - Path permissions → Unraid runs containers as PUID/PGID = 99/100 by default
Output
The generated XML file is placed at:
code
/boot/config/plugins/dockerMan/templates-user/my-<name>.xml
User must confirm before deploying (writing) to that path.
