Reducing Build Time

BUILDKIT_INLINE_CACHE=1 build-argis a neat flag that you could add to your docker build to reduce the build time upto 89%
- pythonspeed.com: Docker BuildKit: faster builds, new features, and now it’s stable Building Docker images can be slow, and Docker’s build system is also missing some critical security features, in particular the ability to use build secrets without leaking them. So over the past few years the Docker developers have been working on a new backend for building images, BuildKit.

What did I learn? While Jib creates 3 layers for Spring Boot app (dependencies, resources and classes), Paketo Buildpacks places resources and classes in the same layer.

Cloud Native Buildpacks
- buildpacks.io: Cloud Native Buildpacks 🌟 transform your application source code into images that can run on any cloud.
- altoros.com: Streamlining the Creation of Docker Images with Cloud Native Buildpacks The new Cloud Native Buildpacks framework changes the obnoxious development chore of Dockerfile writing into a simple, automated operations pipeline. When deploying apps to Kubernetes or other container-as-a-service platforms, the proliferation of nonstandard, unauditable containers built manually via Dockerfiles is a real problem. A few products have emerged to solve this problem, among them Cloud Native Buildpacks (СNB). In this blog post, we explore the capabilities of these buildpacks and explain how to use them in build pipelines to deliver standardized, auditable images as artifacts suitable for deployment.

— Francesco Ciulla (@FrancescoCiull4) May 15, 2021
Environment variables are dynamic-named values that affect how our app will behave when running.
We can define them with Docker:
- at runtime
- in the Dockerfile
- in the Compose file (2 ways)
