How to live without Docker for developers - Part 2 | Native approach to build an image with Buildah

January 13, 2021

As you might already know, Kubernetes is going to drop support for Docker. Starting from version 1.20 that was recently released in December 2020 you will see a deprecation warning for Docker. Docker runtime support will be completely removed from Kubernetes in version 1.22 that will be release in late 2021. After that you will need to switch to one of the other compliant container runtimes, like containerd or CRI-O inside your clusters. Despite both containerd and CRI-O know how to pull docker images and run them and Docker Images Manifest V2 and OCI image specification are almost the same, nobody knows how long Docker images will be supported.

As developers, we need to be prepared to build either docker or OCI images in just a one click and get used to living without Docker.

Therefore I decided to create a series of videos with the common title - How to live without Docker for developers.

In the first episode I showed you how you can easily build an image using Buildah if you already have a Dockerfile. But what to do if you don’t have it? Do you need to create one? Of course - not!

In the second episode I will show you the native approach to build an image from scratch using Buildah commands. As a result, you don't need to create a Dockerfile for your application anymore.

Please check it out and subscribe to my channel to be notified when my new videos will be published.

Thank you in advance.
