My first open source contribution

I created a quick start guide for the Hell Let Loose RCON tool. This was my first open source contribution and I'm a little bit proud. You can read it here or down below.

Digital Ocean HLL RCON

Quick start guide to host the HLL RCON tool on Digital Ocean.

Create Account

Go to digitalocean.com/registration and create a new account if you don't already have one. Do create a virtual machine you need to deposit your credit card.

Create Droplet

A virtual machine is called a Droplet on Digital Ocean. Let's create one. To do this simply create a new project and click on the green "Create" button in the top navigation bar and select Droplet.

  • Choose an image => Marketplace => Docker
  • Choose a plan => Basic => $10/month
  • Choose a datacenter region => select your region
  • Select additional options (optional) => Monitoring
  • Authentication => select Password (Not recommended, only for testing purposes. I highly recommend SSH keys. If you can follow the instructions to create a key, do it. Here is a good blog post how to keep your Droplet secure with SSH and firwall protection)
  • Add backups (optional) => yes/no
  • Here is an exaple how it could look like.
  • Click on the green "Create Droplet" button.
  • Now you have to wait two minutes.

Connect to Droplet

Hover over the IP from the newly created Droplet and copy it. Open your Shell to connect via SSH to it. SHH should be installed on newer Windows systems, so you can start PowerShell.

With SSH key:

ssh root@46.101.167.179 -i /path/to/ssh/key

Without SSH key:

ssh root@46.101.167.179

If you connect to it the first time, you will be prompted with the following warning:

The authenticity of host '46.101.167.179 (46.101.167.179)' can't be established.
ECDSA key fingerprint is SHA256:bUanIdnWoKWKsroqxsfKNnROJKvimV0V3fzMTMwmzPU.
Are you sure you want to continue connecting (yes/no)?

Write yes and press enter.

If everything worked it should look like this:

Update your Droplet

Write apt update and press enter. Write apt upgrade -y and press enter. If you get ask if you want to update your packages to the maintainer version, select no.

Install the RCON tool

Write cd ~/ && git clone https://github.com/MarechJ/hll_rcon_tool.git && cd hll_rcon_tool and press enter.

Write pwd to print the current working directory. You have to be in the /root/hll_rcon_tool directory, otherwise the Docker commands will not work.

root@docker-ubuntu-s-1vcpu-2gb-fra1-01:~/hll_rcon_tool# pwd
/root/hll_rcon_tool

If you don't know how to navigate in this directory, watch a basic Linux commands video on YouTube or ask me on Discord: shargeforce#6702

Edit the .env file your your server credentials, Discord webhooks and Steam API key if you have one. For more information visit github.com/MarechJ/hllrcontool

Make changes to your .env file with nano .env and enter. If you don't know how to use nano, watch a basic Linux commands video on YouTube or ask me again on Discord: shargeforce#6702

Start the RCON tool

Write docker-compose up -d and press enter. Make sure your current working directory is /root/hll_rcon_tool. Double check with pwd. Now you have to wait a few seconds.

If everything worked it should look like this:

Creating hll_rcon_tool_postgres_1 ... done
Creating hll_rcon_tool_redis_1    ... done
Creating hll_rcon_tool_supervisor_1_1 ... done
Creating hll_rcon_tool_backend_1_1    ... done
Creating hll_rcon_tool_frontend_1_1   ... done
Creating hll_rcon_tool_supervisor_2_1 ... done
Creating hll_rcon_tool_backend_2_1    ... done
Creating hll_rcon_tool_frontend_2_1   ... done
Creating hll_rcon_tool_supervisor_3_1 ... done
Creating hll_rcon_tool_backend_3_1    ... done
Creating hll_rcon_tool_frontend_3_1   ... done
root@docker-ubuntu-s-1vcpu-2gb-fra1-01:~/hll_rcon_tool#

Now you can head over to your browser and go to: http://droplet_IP:8010/
