While our Relay Guide walks you through setting up an individual relay, you might want to have a self-managed set of relays/gateways that will spin up and down without you needing to generate a token for each one. This Chef recipe will walk you through generating a reusable admin token, which you can reuse, that brings up its own relay or gateway token to register itself to your strongDM organization.
You can generate an admin token that has only one function: creating relay/gateway tokens. Do this in the Admin UI under Settings / Admin Tokens. Select Create under Relays then click the Create button. Copy the token that is printed to screen as you will need it later, and you cannot get it back.
Note: For more detailed information on creating admin tokens, check out the admin token guide.
The recipe requires a folder structure like this:
strong-dm
├── recipes
│ └── default.rb
└── templates
└── default
└── init.sh.erb
There are two files in there, which we’ll look at in turn.
default.rb
template '/usr/local/bin/sdm-init.sh' do
source 'init.sh.erb'
variables(
myip: node['ec2']['local_ipv4'],
admin_token: Chef::EncryptedDataBagItem.load('strongdm', 'admin-token')['content']
)
mode '0500'
owner 'ubuntu'
notifies :run, 'execute[sdm-init]', :immediately
action :create_if_missing
end
execute 'sdm-init' do
command '/usr/local/bin/sdm-init.sh'
action :nothing
end
Note here that you’ll need to have the admin token generated above located in a Chef encrypted data bag.

Note: This script creates a gateway. To make a relay instead, change the SDM_RELAY_TOKEN
line to ./sdm relay create
.
Of note here:
SUDO_USER
and SUDO_UID
SDM_RELAY_TOKEN
.--name <name>
flag to the sdm relay
command.Log into the Admin UI. In that section, the relay or gateway you created should appear Online, with a heartbeat.
If any errors occur or if the relay does not report “online” status, please contact support@strongdm.com for assistance.
