# docker-netbootxyz

## Overview
The [netboot.xyz docker image](https://github.com/netbootxyz/docker-netbootxyz) allows you to easily set up a local instance of netboot.xyz. The container is a small helper application written in node.js. It provides a simple web interface for editing menus on the fly, retrieving the latest menu release of netboot.xyz, and enables mirroring the downloadable assets from Github to your location machine for faster booting of assets.
It is a great tool for developing and testing custom changes to the menus. If you have a machine without an optical drive that cannot boot from USB then having a local netboot server provides a way to install an OS. If you are looking to get started with netboot.xyz and don't want to manage iPXE menus, you should use the boot media instead of setting up a container.
The container is built upon Alpine Linux and contains several components:
* netboot.xyz [webapp](https://github.com/netbootxyz/webapp)
* Nginx for hosting local assets from the container
* tftp-hpa
* syslog for providing tftp activity logs
Services are managed in the container by [supervisord](http://supervisord.org/).
The container runs fine under ARM-based hosts as well as x86-64.
## Usage
The netboot.xyz docker image requires an existing DHCP server to be setup and running in order to boot from it. The image does not contain a DHCP server service. Please see the DHCP configuration setup near the end of this document for ideas on how to enable your environment to talk to the container. In most cases, you will need to specify the next-server and boot file name in the DHCP configuration. Your DHCP server will need to be assigned a static IP.
### Installing docker
To install docker under Debian and Ubuntu run:
```shell
sudo apt install docker.io
```
### Download the docker image
#### From Github Container Registry
```shell
docker pull ghcr.io/netbootxyz/netbootxyz
```
#### From Docker Hub
```shell
docker pull netbootxyz/netbootxyz
```
The following snippets are examples of starting up the container.
### docker-cli
```shell
docker run -d \
--name=netbootxyz \
-e MENU_VERSION=2.0.76 `# optional` \
-e NGINX_PORT=80 `# optional` \
-e WEB_APP_PORT=3000 `# optional` \
-p 3000:3000 `# sets web configuration interface port, destination should match ${WEB_APP_PORT} variable above.` \
-p 69:69/udp `# sets tftp port` \
-p 8080:80 `# optional, destination should match ${NGINX_PORT} variable above.` \
-v /local/path/to/config:/config `# optional` \
-v /local/path/to/assets:/assets `# optional` \
--restart unless-stopped \
ghcr.io/netbootxyz/netbootxyz
```
#### Updating the image with docker-cli
```shell
docker pull ghcr.io/netbootxyz/netbootxyz # pull the latest image down
docker stop netbootxyz # stop the existing container
docker rm netbootxyz # remove the image
docker run -d ... # previously ran start command
```
Start the container with the same parameters used above. If the same folders are used your settings will remain. If you want to start fresh, you can remove the paths and start over.
### docker-compose
1. Copy [docker-compose.yml.example](https://github.com/netbootxyz/docker-netbootxyz/blob/master/docker-compose.yml.example) to docker-compose.yml
1. Edit as needed
1. Run `docker compose up -d netbootxyz` to start containers in the background
#### Updating the image with docker compose
```shell
docker compose pull netbootxyz # pull the latest image down
docker compose up -d netbootxyz # start containers in the background
```
### Accessing the container services
Once the container is started, the netboot.xyz web application can be accessed by the web configuration interface at `http://localhost:3000` or via the specified port.
Downloaded web assets will be available at `http://localhost:8080` or the specified port. If you have specified the assets volume, the assets will be available at `http://localhost:8080`.
If you wish to start over from scratch, you can remove the local configuration folders and upon restart of the container, it will load the default configurations.
### Local Mirror Access
If you want to pull the Live Images images down from your own mirror, modify the boot.cfg file and override the default `live_endpoint` setting from `https://github.com/netbootxyz` and set it to your deployment IP or domain, e.g. `http://192.168.0.50:8080`. It will then redirect asset download to the local location you set for assets on port `8080` and you can download the assets by using the local assets menu down to your local server. This can result in a much faster boot and load time.
## Parameters
Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `:` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.
| Parameter | Function |
| :----: | --- |
| `-p 3000` | Web configuration interface. |
| `-p 69/udp` | TFTP Port. |
| `-p 80` | NGINX server for hosting assets. |
| `-e WEB_APP_PORT=3000` | Specify a different port for the web configuration interface to listen on. |
| `-e NGINX_PORT=80` | Specify a different port for NGINX service to listen on. |
| `-e MENU_VERSION=2.0.76` | Specify a specific version of boot files you want to use from netboot.xyz (unset pulls latest) |
| `-e TFTPD_OPTS='--tftp-single-port'` | Specify arguments for the TFTP server (this example makes TFTP send all data over port 69) |
| `-v /config` | Storage for boot menu files and web application config |
| `-v /assets` | Storage for netboot.xyz bootable assets (live CDs and other files) |
## DHCP Configurations
This image requires the usage of a DHCP server in order to function properly. If you have an existing DHCP server, usually you will need to make some small adjustments to make your DHCP server forward requests to the netboot.xyz container. You will need to typically set your `next-server` and `boot-file-name` parameters in the DHCP configuration. This tells DHCP to forward requests to the TFTP server and then select a boot file from the TFTP server.
### Examples
These are a few configuration examples for setting up a DHCP server. The main configuration you will need to change are `next-server` and `filename/boot-file-name`. `Next-server` tells your client to check for a host running tftp and retrieve a boot file from there. Because the docker image is hosting a tftp server, the boot files are pulled from it and then it will attempt to load the iPXE configs directly from the host. You can then modify and adjust them to your needs. See [booting from TFTP](https://netboot.xyz/docs/booting/tftp/) for more information.
#### isc-dhcp-server
To install the DHCP server under Debian and Ubuntu run:
```shell
sudo apt install isc-dhcp-server
```
You must edit two files to configure `isc-dhcp-server`. Edit `/etc/default/isc-dhcp-server` and configure at least one of the INTERFACES variables with the name of the interface you want to run the DHCP server on:
```shell
INTERFACESv4="eth0"
```
You'll also need a `/etc/dhcp/dhcpd.conf` looking something like this:
```shell
option arch code 93 = unsigned integer 16;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.34 192.168.0.254; # Change this range as appropriate for your network
next-server 192.168.0.33; # Change this to the address of your DHCP server
option subnet-mask 255.255.255.0;
option routers 192.168.0.1; # Change this to the address of your router
option broadcast-address 192.168.0.255;
option domain-name "mynetwork.lan"; # This is optional
option domain-name-servers 1.1.1.1;
if exists user-class and ( option user-class = "iPXE" ) {
filename "http://boot.netboot.xyz/menu.ipxe";
} elsif option arch = encode-int ( 16, 16 ) {
filename "http://boot.netboot.xyz/ipxe/netboot.xyz.efi";
option vendor-class-identifier "HTTPClient";
} elsif option arch = 00:07 {
filename "netboot.xyz.efi";
} else {
filename "netboot.xyz.kpxe";
}
}
```
Now you can try starting the DHCP server:
```shell
sudo systemctl start isc-dhcp-server
```
To make the dhcp server start automatically on boot:
```shell
sudo systemctl enable isc-dhcp-server
```
## netboot.xyz boot file types
The following bootfile names can be set as the boot file in the DHCP configuration. They are baked into the Docker image:
