## ━━━ FIRST-TIME INSTALL ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
|
|
### Prerequisites
|
|
|
|
- Repo cloned onto the target Unraid server
|
|
- `/boot/config/plugins/varaverk/varaverk.plg` exists on flash (see PLG SETUP below)
|
|
|
|
### Steps
|
|
|
|
```bash
|
|
cd Plugin/
|
|
./dev_install.sh
|
|
```
|
|
|
|
This creates:
|
|
|
|
```
|
|
/usr/local/emhttp/plugins/varaverk → Plugin/unraid/ (symlink)
|
|
```
|
|
|
|
Changes to any file under `Plugin/unraid/` take effect immediately in the browser —
|
|
no restart, no reinstall.
|
|
|
|
### Verify
|
|
|
|
Navigate to the Unraid web UI. **Varaverk** should appear in the Tasks menu.
|
|
Go to **Settings → Other Settings** — a Varaverk tile should also appear there.
|
|
|

|
## ━━━ PLG SETUP ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
|
|
The `.plg` file registers Varaverk with Unraid's plugin system. It enables the cron
|
|
mechanism (`update_cron`) and makes the plugin appear on the **Plugins** management page.
|
|
|
|
Create it once on flash — it persists across reboots:
|
|
|
|
```bash
|
|
mkdir -p /boot/config/plugins/varaverk
|
|
|
|
cat > /boot/config/plugins/varaverk.plg <<'EOF'
|
|
<?xml version='1.0' standalone='yes'?>
|
|
<!DOCTYPE PLUGIN [
|
|
<!ENTITY name "varaverk">
|
|
<!ENTITY author "gmer4lfe">
|
|
<!ENTITY version "2026.05.28">
|
|
]>
|
|
<PLUGIN name="&name;" author="&author;" version="&version;" launch="varaverk/monitor" icon="/plugins/varaverk/icons/varaverk.png">
|
|
</PLUGIN>
|
|
EOF
|
|
```
|
|
|
|
The `.plg` has no packages and no remote URLs — it is local-only and is not published
|
|
to Community Applications.
|
|
|
|
**Cron flow on every boot:**
|
|
1. `event/disks_mounted/rebuild_cron` fires
|
|
2. Copies `varaverk.plg` to `/var/log/plugins/`
|
|
3. Calls `vv_cron_rebuild()` → writes `varaverk.cron` → calls `update_cron`
|
|
4. Unraid merges `varaverk.cron` into `/etc/cron.d/root`
|
|
5. crond picks up all Varaverk jobs
|
|

|
## ━━━ SCRIPTS DIRECTORY SETTING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
|
|
`SCRIPTS_DIR` is the only plugin-level setting. It tells the plugin where to find the
|
|
Configurations directory and all scripts.
|
|
|
|
**Set it via:** Settings → Other Settings → Varaverk → Scripts directory
|
|
|
|
Default: `/boot/config/plugins/varaverk`
|
|
|
|
The value is stored in `/boot/config/plugins/varaverk/varaverk.cfg`:
|
|
|
|
```bash
|
|
SCRIPTS_DIR="/boot/config/plugins/varaverk"
|
|
```
|
|
|
|
All other configuration lives in `Configurations/master.conf` and `Configurations/host*.conf`.
|
|
|
|

|
|
|
|
## ━━━ REPO MOVE PROCEDURE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
|
|
If the repo is cloned to a new path:
|
|
|
|
1. Re-run `dev_install.sh` — removes the stale symlink and creates a new one pointing at the new path
|
|
2. Update `SCRIPTS_DIR` in Settings → Other Settings → Varaverk (or edit `varaverk.cfg` directly on flash)
|
|
|
|
The `.plg` on flash does not need to change — it has no path references.
|
|
|

|
|
## ━━━ UPDATING THE PLUGIN VERSION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
|
|
The version in `/boot/config/plugins/varaverk.plg` is cosmetic for a local plugin —
|
|
Unraid does not check it against anything remote. Update it when you want the Plugins
|
|
management page to reflect when the plugin was last changed:
|
|
|
|
```xml
|
|
<!ENTITY version "2026.05.28">
|
|
```
|
|
|

|
|
## ━━━ ADDING A NEW OS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
|
|
`dev_install.sh` is built to support multiple OS targets. To add one:
|
|
|
|
1. Create `Plugin/<os>/` with the OS-appropriate web app files
|
|
2. Add the OS marker to `detect_os()` in `dev_install.sh`:
|
|
```bash
|
|
elif [[ -f /etc/<os>-marker ]]; then echo "<os>"
|
|
```
|
|
3. Add the install target to the `case` block:
|
|
```bash
|
|
<os>)
|
|
SOURCE="$SCRIPT_DIR/<os>"
|
|
TARGET="/path/to/web/server/plugins/$PLUGIN_NAME"
|
|
;;
|
|
```
