Introducing microservices and Docker with a whiteboard and a marker pen :)

Hi team! some months ago I made a very educative and visual video explaining **microservices** and **Docker** from the perspective of being interesting, fun and useful. I just want to share the content here. I hope some of you may found it interesting and useful. Thank you and have a nice day!

Podman 3 and Docker Compose - How Does the Dockerless Compose Work?

One of the main Podman 3 features is the support of Docker Compose. You can take any of your existing docker-compose.yml and just use it with Podman. In my new short video, I am showing how I moved from Docker to Podman in a real docker-composed application:

What is Tekton and how it compares to Jenkins, Gitlab CI and other CI/CD systems

I think there is often a confusion about Tekton - it's not really a complete CI/CD system, but rather a Lego. I made a video explaining this point:

Is Tekton alive? Comparing Tekton Pipelines with Argo Workflows, ArgoCD and Jenkins

Is Tekton still alive? I’ve successfully used this tool in an Openshift environment, where it makes all the sense - there is a proper integration with the platform itself, and RedHat puts lots of effort into making a real CI/CD system out of it. But do Tekton Pipelines make sense today without a wrapper like Pipeline as Code and JenkinsX on top? And are there many companies actually using Tekton, compared to Argo and similar tools? I tried to answer all of these questions in this new mkdev video, plus did some experiments again with editing - hope it’s now even more fun and engaging to watch it, but feel free to roast me in the comments.

Argo Ecosystem: Argo CD, Argo Workflows, Argo Events, Argo Rollouts, Argo Everything

I feel like not everyone realizes, that Argo is a whole ecosystem today, with different tools covering different use cases, but all working together in a very nice combo. I made a short video explaining Argo ecosystem: https://youtu.be/ae0XJGJPLvo
