NAME

shoelaces - automated server bootstrapping

SYNOPSIS

shoelaces [options...]

OPTIONS

-base-url <string>

Optional parameter. Specifies the base address that will be used when generating URLs. If it’s not specified, the value of "-bind-addr" will be used.

-bind-addr <host:port>

The address where Shoelaces will listen for requests. Defaults to "localhost:8081".

-config <config>

Specifies a config file. All the following options can be specified in the config.

-data-dir <directory>

Specifies a directory with mappings, configs, templates, etc.

-debug

Enables debug mode.

-env-dir <directory>

Specifies a directory with environment overrides. Refer to the README of the project for more information about environment overrides.

-mappings-file <file>

Specifies a mappings YAML file. Defaults to "mappings.yaml". Refer to the README of the project for more information about mappings.

-static-dir <directory>

Specifies a custom web directory with static files. Defaults to "web".

-template-extension <extension>

Shoelaces template extension. Defaults to ".slc".

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:

bind-addr=localhost:8081
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.
