An open-source container management engine called Kubernetes is used to automatically launch, scale, and handle containerized apps. The fundamental unit of a Kubernetes program is a pod. Instead of managing containers, Kubernetes controls pods, and pods enclose containers. A number of containers, storage, IP addresses, and settings that control how containers should operate inside the pod can all be found in a pod. You can operate two closely linked containers together with sidecar containers.

Speed and efficiency are paramount during the build process. If you use a Dockerfile to build your container images from source code, you want to know about build cache. In this blog post, we’ll talk about what happens when you create a Docker image using a Dockerfile, how caching works with Docker, and how to optimize your Dockerfiles to maximize the benefits of build cache with Docker and on Koyeb.
