What are some specific examples of bugs that may occur that having one single source of truth via congruent containers fixes?

[@interviewpen]

Assuming you're referring to having a reproducible container on any machine... One really common issue is having the wrong version of a runtime, for example your dev environment runs python 3.10 while production runs python 3.9. Everything might work fine on your dev machine, but as soon as you deploy, you'll face bugs from having a different python version. Similar issues arise with libraries compiled for a specific operating system, or having pertinent files stored in random places on your dev machine, etc. Hope that helps!
