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

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling 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 Available Tag
x86-64 amd64-<version tag>
arm64 arm64v8-<version tag>

Version Tags

This image provides various versions that are available via tags. Please read the descriptions carefully and exercise caution when using unstable or development tags.

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

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 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.

Router Setup Examples


Services -> DHCP Server

Set both the option for "TFTP Server" and the options under the Advanced "Network Booting" section.n * check enable * Next server- IP used for TFTP Server * Default BIOS file name- * UEFI 32 bit file name- * UEFI 64 bit file name-


Services -> DHCP Server

Under the Advanced "Network Booting" section. * check enable * Next server- IP of docker host * Default BIOS file name- * UEFI 32 bit file name- * UEFI 64 bit file name-

Unifi Security Gateway (with the controller)

Networks -> LAN (or the network you want to boot from) -> ADVANCED DHCP OPTIONS * tick Enable network boot * Server- YOURSERVERIP * Filename- Advanced full support * For USG variants force provisioning a json containing the same config used for EdgeOS (shown below) will fully support netboot. * For UDM variants, creating a valid dnsmasq config and placing in /run/dnsmasq.conf.d will load the config, but will not survive reboots or firmware updates source.

Various locations to set Additional/Custom DNSMASQ options in UI or config files Set the following lines:

Ensure you restart the DNSMASQ service after the changes.

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-
  • UEFI 32 bit file name-
  • UEFI 64 bit file name-

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 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.


To help you get started creating a container from this image you can either use docker-compose or the docker cli.

    container_name: netbootxyz
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
      - MENU_VERSION=1.9.9 #optional
      - PORT_RANGE=30000:30010 #optional
      - SUBFOLDER=/ #optional
      - NGINX_PORT=80 #optional
      - WEB_APP_PORT=3000 #optional
      - /path/to/config:/config
      - /path/to/assets:/assets #optional
      - 3000:3000
      - 69:69/udp
      - 8080:80 #optional
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=netbootxyz \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -e MENU_VERSION=1.9.9 `#optional` \
  -e PORT_RANGE=30000:30010 `#optional` \
  -e SUBFOLDER=/ `#optional` \
  -e NGINX_PORT=80 `#optional` \
  -e WEB_APP_PORT=3000 `#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 \


Containers 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
TZ=Etc/UTC specify a timezone to use, see this list.
MENU_VERSION=1.9.9 Specify a specific version of boot files you want to use from NETBOOT.XYZ (unset pulls latest)
PORT_RANGE=30000:30010 Specify the port range tftp will use for data transfers (see Wikipedia)
SUBFOLDER=/ Specify a sobfolder if running this behind a reverse proxy (IE /proxy/)
NGINX_PORT=80 Specify a different internal port for the asset server
WEB_APP_PORT=3000 Specify a different internal port for the configuration UI

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)

Miscellaneous Options

Parameter Function

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__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable 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 your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

  • Shell access whilst the container is running:

    docker exec -it netbootxyz /bin/bash
  • To monitor the logs of the container in realtime:

    docker logs -f netbootxyz
  • Container version number:

    docker inspect -f '{{ index .Config.Labels "build_version" }}' netbootxyz
  • Image version number:

    docker inspect -f '{{ index .Config.Labels "build_version" }}'

Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant, we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

  • Update images:

    • All images:

      docker-compose pull
    • Single image:

      docker-compose pull netbootxyz
  • Update containers:

    • All containers:

      docker-compose up -d
    • Single container:

      docker-compose up -d netbootxyz
  • You can also remove the old dangling images:

    docker image prune

Via Docker Run

  • Update the image:

    docker pull
  • Stop the running container:

    docker stop netbootxyz
  • Delete the container:

    docker rm netbootxyz
  • Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)

  • You can also remove the old dangling images:

    docker image prune

Image Update Notifications - Diun (Docker Image Update Notifier)


We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone
cd docker-netbootxyz
docker build \
  --no-cache \
  --pull \
  -t .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
