A Bavarian living in France working on all-things containers.

Valentin is a principal software engineer in Red Hat's container engines team, focusing on and maintaining various open-source projects such as Buildah, Podman, Skopeo and CRI-O. He contributed to many other projects in the containers landscape such as Kubernetes, the Linux kernel, Moby, Google Cloud, container-diff and more. Prior to industry, Valentin has been working in academia researching and teaching operating systems.

Podman - create, run and secure Linux containers

I want to give a deep dive into Podman, a community-driven, open source container engine. While I only scratched the surface of Podman at Code Mesh 2019, I want to dedicate a full talk in 2020.

Why is Podman more secure than other container engines? Why can Podman better integrate into modern Linux systems? These and many more questions will be addressed in my talk along with hands-on examples showing recent developments in Podman 2.0, such as:

* A new Docker compatible REST API for remote clients
* Go and Python bindings for the new REST API
* Improved integration of Podman and systemd, and auto updates


I will explain in greater detail the attributes and challenges of a modern container engine such as Podman and how it integrates into modern Linux systems. The audience will learn some basics and advanced features of Podman (and Linux), how we can swap Docker with Podman and how we can further secure and lock down containers.


Developers, system administrators, IT managers, students, researchers. Anybody interested in containers.

Decomposing container tools - about Swiss Army Knives and containers

One-size-fits-all solutions come at a price. In this talk, I present four open-source container tools dedicated to specific use-cases:

  • CRI-O, a Kubernetes runtime
  • Podman, for managing pods and containers
  • Buildah, for building containers
  • Skopeo, for distributing container images

All tools are collaboratively developed across the industry and distributions, and are built on top of the same libraries, allowing for a seamless integration, compatibility and interoperability. Live demos demonstrate how they can cover an entire life-cycle: from local development to migrating to production.


No one-size-fits-all solutions


The main objective of the talk is to share the philosophy of the four tools. Having a more narrow focus allows for innovation in the target use-cases, and offers a less-opinionated experience for end-users and customers, offering choice and flexibility.


Everybody interested in running and building containers, locally, on a server, and in distributed environments such as Kubernetes.
