Netbootxyz is a way to PXE boot various operating system installers or utilities from one place within the BIOS without the need of having to go retrieve the media to run the tool. iPXE is used to provide a user friendly menu from within the BIOS that lets you easily choose the operating system you want along with any specific types of versions or bootable flags.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling linuxserver/netbootxyz should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture Tag
x86-64 amd64-latest
arm64 arm64v8-latest
armhf arm32v7-latest

Version Tags

This image provides various versions that are available via tags. latest tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.

Tag Description
latest Web application for full self hosting
tftp TFTP server only with NETBOOT.XYZ boot files

Usage

Here are some example snippets to help you get started creating a container from this image.

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
  netbootxyz:
    image: linuxserver/netbootxyz
    container_name: netbootxyz
    environment:
      - PUID=1000
      - PGID=1000
      - MENU_VERSION=1.9.9 #optional
    volumes:
      - /path/to/config:/config
      - /path/to/assets:/assets #optional
    ports:
      - 3000:3000
      - 69:69/udp
      - 8080:80 #optional
    restart: unless-stopped

docker cli

docker run -d \
  --name=netbootxyz \
  -e PUID=1000 \
  -e PGID=1000 \
  -e MENU_VERSION=1.9.9 `#optional` \
  -p 3000:3000 \
  -p 69:69/udp \
  -p 8080:80 `#optional` \
  -v /path/to/config:/config \
  -v /path/to/assets:/assets `#optional` \
  --restart unless-stopped \
  linuxserver/netbootxyz

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> 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.

Ports (-p)

Parameter Function
3000 Web configuration interface.
69/udp TFTP Port.
80 NGINX server for hosting assets.

Environment Variables (-e)

Env Function
PUID=1000 for UserID - see below for explanation
PGID=1000 for GroupID - see below for explanation
MENU_VERSION=1.9.9 Specify a specific version of boot files you want to use from NETBOOT.XYZ (unset pulls latest)

Volume Mappings (-v)

Volume Function
/config Storage for boot menu files and web application config
/assets Storage for NETBOOT.XYZ bootable assets (live CDs and other files)

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Application Setup

To use this image you need an existing DHCP server where you can set this TFTP server as your DHCP boot destination. This image does not contain a DHCP server nor do we aim to support one in the future. This is simply a TFTP server hosting the latest IPXE kernel builds from netboot.xyz. If you are interested in their project and lack the ability to setup a DHCP server to boot this payload they also have USB stick images you can use available on their downloads page.

Microsoft Server DHCP

  • Run the DHCP program
  • Under Scope/Scope Options
  • check option 066 and enter the FQDN or IP of your TFTP boot server
  • check option 067 and enter one of the following bootfile names:
    • Default BIOS file name- netboot.xyz.kpxe
    • UEFI 32 bit file name- netboot.xyz.efi
    • UEFI 64 bit file name- netboot.xyz.efi

Anything else from a router standpoint is a crapshoot for supporting Dnsmasq options or proprietary PXE boot options, check Google for support (try your exact router model number with 'pxe boot') or look into setting up your own DHCP server in Linux.

This image also contains netboot.xyz.efi which can be used to boot using UEFI network boot. The UEFI boot and menu will have limited functionality if you choose to use it.
