Are you tired of cluttering your OS with unnecessary dependencies and dev tools for side projects that you might only use once? Do you want a simple way to keep all your project assets together? If so, you should try using systemd-nspawn to create lightweight Linux containers for your projects.
First, create a minimal Debian install using the debootstrap command:
sudo debootstrap stable `pwd`/os/
or (in my particular use case, I'm working with Debian unstable)
sudo debootstrap unstable `pwd`/os/
This will create a container that is only 240 megabytes in size.
Next, start the container using the following command:
sudo systemd-nspawn -D `pwd`/os -M MACHINENAME
Once the container is started, you can set up an account by running the following commands:
# set up account useradd -m user passwd user
To set up software, run the following commands:
# this may be necessary on debian stable apt install ca-certificates # set up software apt update apt install nano vim curl # etc
With these simple steps, you can easily create lightweight Linux containers for your development and experimentation projects using systemd-nspawn.
