## Boot
LinuxKit on Packet boots the `kernel+initrd` output from moby
via
[iPXE](https://help.packet.net/technical/infrastructure/custom-ipxe). iPXE
booting requires a HTTP server on which you can store your images. At
the moment there is no builtin support for this, although we are
working on this too.
booting requires a HTTP server on which you can store your images. The
`-base-url` option specifies the URL to the HTTP server.
A simple way to host files is via a simple local http server written in Go, e.g.:
If you don't have a public HTTP server at hand, you can use the
`-serve` option. This will create a local HTTP server which can either
be run on another Packet machine or be made accessible with tools
like [ngrok](https://ngrok.com/).
```Go
package main
import (
"log"
"net/http"
)
func main() {
// Simple static webserver:
log.Fatal(http.ListenAndServe(":8080", http.FileServer(http.Dir("."))))
}
```
and then `go run` this in the directory with the `kernel+initrd`.
The web server must be accessible from Packet. You can either run the
server on another Packet machine, or use tools
like [ngrok](https://ngrok.com/) to make it accessible via a reverse
proxy.
You then specify the location of your http server using the
`-base-url` command line option. For example, to boot the
toplevel [linuxkit.yml](../linuxkit.yml) example:
For example, to boot the toplevel [linuxkit.yml](../linuxkit.yml)
example with a local HTTP server:
```sh
moby build linuxkit.yml
# run the web server
# run 'ngrok http 8080' in another window

**Note**: It may take several minutes to deploy a new server. If you
