Installing dependencies

While Balancer operates independently without relying on third-party services, it does require certain open-source software to be installed on the host machine running the instance. Ensuring these dependencies are properly set up is essential for a smooth deployment.

Before proceeding, run the following command to update the packages used by the OS:

sudo apt update -y && sudo apt upgrade -y && sudo apt-get update -y && sudo apt-get upgrade -y

Tip: you can paste into the terminal by pressing Ctrl+Shift and then V.


Installing Docker

  1. Set up Docker's apt repository:

    # Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

  2. Install the Docker Packages:

    sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

  3. Verify that the installation is successful by running the hello-world image:

    sudo docker run hello-world

Installing nvm

The nvm bash script can be installed as follows:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

If the above command fails, run this one:

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

Once nvm's installation is complete, install and activate the version required by Balancer (Node.js ^22.11.0 & npm ^10.9.0):

nvm install 22.11.0 && nvm use 22.11.0

If you get the error nvm: command not found or see no feedback on the terminal, reboot the machine by running the following command: reboot now.

Finally, verify the installation was successful:

node --version && npm --version
# v22.11.0
# 10.9.0
