Configuring pam_pwquality on Ubuntu
It's important to use strong passwords on your Linux system. Brute-force attacks regularly happen during other intrusions to the network, and strong passwords will prevent easy movement between systems. When any system has been successfully attacked there is a risk of offline brute-forcing of captured password files, and in this case reused passwords between systems will be quickly discovered.

It allows you to run containers that package up pieces of software in a way that is portable and reproducible.
