Dockerize

Verb · Slang & Abbreviations · Origin: 2013

Definitions

  1. To package an application and its dependencies into a Docker container. 'Can you Dockerize the service by end of day?' has replaced 'can you write deployment docs?'

    In plain English: To package an application along with everything it needs to run into a neat container, so it works the same way on any computer — no more 'but it works on my machine.'

  2. The process involves writing a Dockerfile (build instructions), building an image, and pushing it to a registry. Common pitfalls include bloated images (use multi-stage builds), running as root (add a USER directive), and baking secrets into images (use environment variables or secrets management).

    Example: 'Dockerizing the app took an hour. Getting the image size from 1.2GB to 85MB with multi-stage builds took another day.'
