# DESCRIPTION

Shoelaces serves over HTTP iPXE boot scripts, cloud-init configuration, and
any other configuration files to baremetal or virtual machines booting
using iPXE. It also does a few other things to make easier managing server
deployments:

- Has a simple but nice UI to show the current configuration, and history
  of servers that booted.
- Uses Go templates to handle complex configurations.
- Allows specifying the boot entry point for a given server based on its IP
  address or DNS PTR record.
- Supports the notion of environments for Development and Production
  environment configurations, while trying to minimize template
  duplication.
- Puts unknown servers into iPXE script boot retry loop, while at the same
  time showing them in the UI allowing the user to select a specific boot
  configuration.

Shoelaces is better when used along a DHCP server. Refer to the
*CONFIGURATION* section for examples on how to configure a DHCP server for
hooking it with Shoelaces.

# CONFIGURATION

Shoelaces searches for a config file whenever the *-config* flag is
specified.

Here is example config file:

```
port=8081
domain=localhost
data-dir=/etc/shoelaces/data-dir/
template-extension=.slc
mappings-file=mappings.yaml
debug=true
```

*dhcpd*(8) can be hooked with Shoelaces by adding the following snippet in
*dhcpd.conf*(5):

```
# dhcp.conf
next-server <your-tftp-server>;
if exists user-class and option user-class = "iPXE" {
  filename "http://<shoelaces-server>/poll/1/${netX/mac:hexhyp}";
} else {
  filename "undionly.kpxe";
}
```

Similarly, *dnsmasq*(8) can be configured for working with Shoelaces with
the following snippet:

```
dhcp-match=set:ipxe,175 # iPXE sends a 175 option.
dhcp-boot=tag:!ipxe,undionly.kpxe
dhcp-boot=http://<shoelaces-server>/poll/1/${netX/mac:hexhyp}
```

A TFTP server such as *tftpd*(8) must be configured to serve the IPXE ROM,
*undionly.kpxe*.
