CoreOS rkt / Container Linux (project ended) vs. Podman.io

It is very well suited for local testing where one knows what is being worked on and knows all the dependencies of the software project. On the other hand, it would be less appropriate in situations where a simple chroot can do the trick without the overhead of running a Go application.

While it always depends on your use case, I believe security concerns of need for root user is a concern, so it is worth considering daemonless container service over Docker, which works just as good and has support for docker compose. Another good reason is the licensing for enterprise usage, which podman has no restrictions for. It’s also a great choice for OpenShift integration, which is seamless and works well with Rancher as well.

• Running a secure container without messing up with low-level details
• Very clear and straightforward approach to building a container
• A way to go for new projects thinking of containers
• Comprehensive and well-written documentation compatible with UNIX keep it simple way of thinking

• It’s daemonless, so somewhat more secure.
• It works exceptionally well and is compatible with Docker compose
• Podman Desktop actually makes individual usage also pretty easy.
• It can be used as Docker alternative with almost no additional steps

• Market share, it's often very difficult to find new talent who use CoreOS rkt.
• Lack of wow features, CoreOS rkt doesn't necessarily offer any immediate advantages over other container solutions.

• Podman desktop is getting more stable with each version, but does need more UX friendliness as well.
• Official support for development tools and IDEs is missing for most tools
• It works well with Kubernetes, but I wouldn’t mind additional improvements

We evaluated CoreOS rkt and Docker when selecting software solutions for my department. We ended up using CoreOS rkt because of how well it fits with CoreOS and the choice of gRPC for the API. We provide a managed service that runs CoreOS on a bare metal server, CoreOS rkt was a logical choice for compatibility. We also found that developers were having better scusess interacting with gRPC than other container engines REST protocols. It was a close race but eventually there were just enough small benefits to push CoreOS rkt in front of the competition.

Podman is Daemonless, lightweight and doesn’t charge us for commercial usage, so it’s a relief for startups. Minikube and Rancher are a bit more complex for our use cases; so we keep things simple, fast and secure with Podman that can easily be managed with Podman Desktop and other works with our docker-compose based projects without issues.

Incentivized

• Developers spend less time configuring and more time coding.
• Less time training developers as CoreOS rkt lets them use whatever hardware and operating system they want.
• Reduced our IT costs, solutions are containerized using CoreOS rkt meaning they can write one solution with many developers in mind.

Incentivized

• We definitely feel more secure.
• We do not suffer from memory or cpu overuses as it uses fedora coreOS which is lightweight
• We do not have to worry about license payments for our basic usages.
• It’s open source so quick fixes imminent with maximum transparency.
