# UDM / UDMPro Boot Script

## Features

1. Allows you to run a shell script at S95 anytime your UDM starts / reboots

## Compatibility

1. Should work on any UDM/UDMPro after 2.4.x


* [build_deb.sh](build_deb.sh) can be used to build the package by yourself.
    * [dpkg-build-files](dpkg-build-files) contains the sources that debuild uses to build the package if you want to build it yourself / change it
    * by default it uses docker or podman to build the debian package
    * use ```./build_deb.sh build``` to not use a container
    * the resulting package will be in [packages/](packages/)

* Built on Ubuntu-20.04 on Windows 10/WSL2

## Install

You can execute in UDM/Pro/SE and UDR with:

```bash
curl -fsL "https://raw.githubusercontent.com/unifi-utilities/unifios-utilities/HEAD/on-boot-script/remote_install.sh" | /bin/sh
```

This is a force to install script so will uninstall any previous version and install on_boot keeping your on boot files.

This will also install CNI Plugins & CNI Bridge scripts. If you are using UDMSE/UDR remember that you must install podman manually because there is no podman.

## Manually Install Steps

1. Get into the unifios shell on your udm

    ```bash
    unifi-os shell
    ```

2. Download [udm-boot-2x_1.0.1_all.deb](packages/udm-boot_1.0.0-2x_all.deb) and install it and go back to the UDM.

    ```bash
    curl -L [[https://udm-boot.boostchicken.dev](https://unifi.boostchicken.io/udm-boot-2x_1.0.0_all.deb)](https://unifi.boostchicken.io/udm-boot-2x_1.0.0_all.deb) -o udm-boot-2x_1.0.0_all.deb
    dpkg -i udm-boot-2x_1.0.0_all.deb
    systemctl enable udm-boot
    exit
    ```

3. Copy any shell scripts you want to run to /mnt/data/on_boot.d on your UDM (not the unifi-os shell) and make sure they are executable and have the correct shebang (#!/bin/sh). Additionally, scripts need to have a `.sh` extention in their filename.

    Examples:
    * Start a DNS Container [10-dns.sh](../dns-common/on_boot.d/10-dns.sh)
    * Start wpa_supplicant [on_boot.d/10-wpa_supplicant.sh](examples/udm-files/on_boot.d/10-wpa_supplicant.sh)
    * Add a persistent ssh key for the root user [on_boot.d/15-add-root-ssh-keys.sh](examples/udm-files/on_boot.d/15-add-root-ssh-keys.sh)
