Release 3.0 release of podman comes with support for Docker Compose, improved security, and over 100 bug fixes.

This post gives some general security advice in working with .NET containers.

Report on scanning publicly available Docker Hub images for vulnerabilities. It isn’t the first analysis of this kind, but the result is the same: There are still many harmful container images out there.

The author explains a typical use case of skopeo. The tool comes in handy in every situation where you have to get container images from A to B.

A compiled list of links to public failure stories related to Kubernetes.

In competing visions of the future of Kubernetes, Paul Czarkowski, principal technologist at Pivotal, predicts that VMs will replace containers, and Joe Fernandes, a VP at Red Hat, considers that VMs usage is evolving for Kubernetes rather than replacing containers. In addition, Chris Short, Red Hat's principal product marketing manager, said that Kubernetes is close to replacing the hypervisor.

TL;DR: containers are not VMs; stop calling everything "Docker"; don't use Kubernetes for tiny projects, use Swarm instead; Kubernetes will only solve your org's problems if you are willing to go all-in, anything in between will fail the same way it failed before.

Versions of the Official Alpine Linux Docker images (since v3.3) contain a NULL password for the root user.

The vulnerability allows a malicious container to (with minimal user
interaction) overwrite the host runc binary and thus gain root-level
code execution on the host.
