Docker
Since this project utilizes Docker technologies extensively, it is necessary to provide documentation on Docker.
Before reading books on Docker, one can start reading some of the following articles:

Some Utilities to run Docker
"See this docker container? I wish I could run another one just like it,
but I'll be damned if I'm going to type all those command-line switches manually!"
Docker Installation Mysteries
There are two main packages for Docker installation, docker.io and containerd.io. If your network doesn't resolve certain repository site, you might not be able to install the software properly, and you might not be given the signals about why. In my case, I used a VPN service to pretend my computer is situated in the USA, and some problems are resolved. The particular case in point is here:
echo "[TASK 5] Install containerd runtime"
apt update -qq >/dev/null 2>&1
apt install -qq -y containerd apt-transport-https >/dev/null 2>&1
mkdir /etc/containerd
containerd config default > /etc/containerd/config.toml
systemctl restart containerd
systemctl enable containerd >/dev/null 2>&1
Install software from local repository
One way to avoid software download problems is to install a local instance of software repository. Relevant information can be found here: Set up Local Repository for Ubuntu.
