Best Practices for Building Containers


This article describes a set of best practices for building containers. These practices cover a wide range of goals, from shortening the build time, to creating smaller and more resilient images, with the aim of making containers easier to build (for example, with Cloud Build), and easier to run in Kubernetes Engine. These best practices are not of equal importance. For example, you might successfully run a production workload without some of them, but others are fundamental. In particular, the importance of the security-related best practices is subjective. Whether you implement them depends on your environment and constraints. To get the most out of this article, you need some knowledge of Docker and Kubernetes. Some best practices discussed here also apply to Windows containers, but most assume that you are working with Linux containers.
