Asteroid

Asteroid is a tool designed to help you manage your Wireguard server.

It supports :

• Viewing the configuration to check peers/IP relation
• Adding a new peer
• Removing a peer
• Generating Client config file

Installation

Via source

First you need to clone the repo:

$ git clone https://github.com/dailymotion/asteroid.git

Once you have it in your folder, just build it with:

go build -o asteroid ./cmd/asteroid

This will create a binary that can be run with ./asteroid

Via Docker

First you need to clone the repo:

$ git clone https://github.com/dailymotion/asteroid.git

Once you have it in your folder, just build it with:

docker build -t asteroid .

To finish, run it with:

docker run --rm -v path_to_your_ssh_key:/home/asteroid/.ssh/ssh_key_name -v path_to_your_asteroid_config.yaml:/home/asteroid/.asteroid.yaml asteroid

Configuration

To configure Asteroid, you just have to copy the expample config file located in pkg/config/asteroid_example.yaml into your user root folder (~/ or /home/username) as .asteroid.yaml and change the values inside

cp pkg/config/asteroid_example.yaml ~/.asteroid.yaml

Use cases

Viewing the configuration

If you want to check how much peers you have on your server and be able to pinpoint which ip they relate to, use the view flag

$ asteroid view
$ docker run --rm -v path_to_your_ssh_key:/home/asteroid/.ssh/ssh_key_name asteroid view
+----------------------------------------------+------------+
|                     PEER                     |  LOCAL IP  |
+----------------------------------------------+------------+
| eXaMPL3Ave8q+Da!L!m0ti0niXc//M0EGOY6K9C11nw= | 172.16.0.2 |
| eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C12nw= | 172.16.0.4 |
| eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C13nw= | 172.16.0.5 |
| eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C14nw= | 172.16.0.6 |
+----------------------------------------------+------------+

Adding a peer

As one of the perk of asteroid is to let you add new peer, you just have to prepare the peer public key and it's Wireguard IP

$ asteroid add -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw=" -address "172.16.0.x/xx"
$ docker run --rm -v path_to_your_ssh_key:/home/asteroid/.ssh/ssh_key_name asteroid add -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw=" -address "172.16.0.x/xx"
  
  Peer: eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw= has been added !

Deleting a peer

If you need for any reasons to remove a peer from the server, a simple way to do it will be with the delete command:

$ asteroid delete -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw="
$ docker run --rm -v path_to_your_ssh_key:/home/asteroid/.ssh/ssh_key_name asteroid delete -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw="
 
  Peer: eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw= has been deleted !

Generating a stdout of the client Wireguard config

If you need, for the peer added to generate a Wireguard stdout, you can do it with the flag -generateStdout

$ asteroid add -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw=" -address "172.16.0.x/xx" -generateStdout
$ docker run --rm -v path_to_your_ssh_key:/home/asteroid/.ssh/ssh_key_name asteroidadd -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw=" -address "172.16.0.x/xx" -generateStdout
 
   Peer: eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw= has been added !
   
   Client config output
   ---------------
   [Interface]
   PrivateKey = eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw= 
   Address = xx.xx.xx.xx/32
   DNS = 9.9.9.9
  
   [Peer]
   PubblicKey = eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw= 
   AllowedIPs = 0.0.0.0/0
   EndPoint = public_ip_of_your_wireguard:51820

Generating client config file

If you need, for the peer added to generate its Wireguard config, you can do it with the flag -generateFile
It's possible to change it's name via the asteroid.yaml config file

$ asteroid add -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw=" -address "172.16.0.x/xx" -generateFile
$ docker run --rm -v path_to_your_ssh_key:/home/asteroid/.ssh/ssh_key_name asteroidadd -key "eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw=" -address "172.16.0.x/xx" -generateFile
 
  Peer: eXaMPL3Ave8q+kmNVmiw4KdKiXc//M0EGOY6K9C11nw= has been added !
  The wireguard config for the client has been created with the name: wg0.conf

Help

If you need any help with the command and their respective arguments, just use help:
