Speed Up Your Development Flow With These Dockerfile Best Practices

The Dockerfile is the starting point for creating a Docker image. The file format provides a well-defined set of directives that allow you to copy files or folders, run commands, set environment variables, and do other tasks required to create a container image. It’s really important to craft your Dockerfile well to keep the resulting image secure, small, quick to build, and quick to update.

In this post, we’ll see how to write good Dockerfiles to speed up your development flow, ensure build reproducibility and that produce images that can be confidently deployed to production.
