Container in the data science domain
Think of Docker container as a zip file. A zip file that also includes a full-fledged software application that runs the data analysis code.
If you need to handover the data analysis in the exact computer set-up so your client or project stakeholder can run at their end and keep it on-premise, Docker Container is the way. Container is one of the end product of a data analysis.
Fighting with dependencies is can be difficult; nobody wants to sink hours into sorting out which version of which package is needed to reproduce the data analytics results. Like version control for code, a Docker image allows you to go back – allowing you to experiment fearlessly without messing up your PC .
