Boots

This service handles DHCP, PXE, tftp, and iPXE for provisions in the Tinkerbell project. For more information about the Tinkerbell project, see: tinkerbell.org.

Running Boots

As boots runs a DHCP server, it's often asked if it is safe to run without any network isolation; the answer is yes. While boots does run a DHCP server, it only allocates an IP address when it recognizes the mac address of the requesting device.

Local Setup

Running the Tests

# run the tests
make test

Build/Run Boots

# make the binary
make boots
# run boots
./cmd/boots/boots -h

USAGE
  Run Boots server for provisioning

FLAGS
  -dhcp-addr              IP and port to listen on for DHCP. (default "172.17.0.3:67")
  -http-addr              local IP and port to listen on for the serving iPXE binaries and files via HTTP. (default "172.17.0.3:80")
  -ipxe-enable-http       enable serving iPXE binaries via HTTP. (default "true")
  -ipxe-enable-tftp       enable serving iPXE binaries via TFTP. (default "true")
  -ipxe-remote-http-addr  remote IP and port where iPXE binaries are served via HTTP. Overrides -http-addr for iPXE binaries only.
  -ipxe-remote-tftp-addr  remote IP where iPXE binaries are served via TFTP. Overrides -tftp-addr.
  -ipxe-tftp-addr         local IP and port to listen on for serving iPXE binaries via TFTP (port must be 69). (default "0.0.0.0:69")
  -ipxe-tftp-timeout      local iPXE TFTP server requests timeout. (default "5s")
  -log-level              log level. (default "info")
  -syslog-addr            IP and port to listen on for syslog messages. (default "172.17.0.3:514")

You can use NixOS shell, which will have Go and others

nix-shell

Developing with Standalone Mode

The quickest way to get started is docker-compose up. This will start boots in standalone mode using the example JSON in the test/ directory. It also starts a client container that runs some tests.

docker-compose build # build containers
docker-compose up    # start the network & services
# it's fine to hit control-C twice for fast shutdown
docker-compose down  # stop the network & clean up Docker processes

Alternatively you can run boots standalone manually. It requires a few environment variables for configuration.

test/standalone-hardware.json should be safe enough for most developers to use on the command line locally without getting a call from your network administrator. That said, you might want to contact them before running a DHCP server on their network. Best to isolate it in Docker or a VM if you're not sure.
