Buildah might be a bit more popular than runc. We know about 10 links to it since March 2021 and only 8 links to runc. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
In my experience, not using docker to build docker images is a good idea. E.g. buildah[0] with chroot isolation can build images in a GitLab pipeline, where docker would fail. It can still use the same Dockerfile though. If you want to get rid of your Dockerfiles anyway, nix can also build docker images[1] with all the added benefits of nix (reproducibility, efficient building and caching, automatic layering,... - Source: Hacker News / 6 months ago
Buildah: This lightweight, open-source command-line tool for building and managing container images. It is an efficient alternative to Docker. With Buildah, you can build images in various ways, including using a Dockerfile, a podmanfile or by running commands in a container. Buildah is a flexible, secure and powerful tool for building container images. - Source: dev.to / 11 months ago
When I saw the title I thought it was going to be about `buildah` [1][2] Which allows you to create images using the command line to build them up step-by-step. [1] https://buildah.io/. - Source: Hacker News / over 1 year ago
Buildah is a "tool that facilitates building OCI images" of Containers. If it is not installed, podman system migrate will print out the warning:. - Source: dev.to / over 1 year ago
Technically, nothing stops you from building containers without running Docker's Linux VM. After all it's just a file as any other with a known format. I'm not sure though if it's worth the trouble. There are tools for building images other than Docker but I never used any of those and don't know if they are standalone or are wrappers around Docker. Buildah is one of them.

It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C) As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun), which is written in C as an alternative to runc, which is written in Go( - Source: Hacker News / 8 months ago
Yeah, runtimeClass lets you specify which CRI plugin you want based on what you have available. Here's an example from the containerd documentation - you could have one node that can run containers under standard runc, gvisor, kata containers, or WASM. Without runtimeClass, you'd need either some form of custom solution or four differently configured nodes to run those different runtimes. That's how krustlet did... Source: over 1 year ago
Your Docker Container can only run Linux. That's because Docker takes advantage of runC which uses the Linux kernel. You can't run Windows inside of Docker. But of course you can run Docker on a Windows host machine. If you are running a .NET project, you won't be able to use Docker. On the other hand, if you're running .NET Core then you're in luck! - Source: dev.to / over 1 year ago
This is what Podman, an open-source daemonless and rootless container engine, was developed with in mind. Podman runs using the runC container runtime process, directly on the Linux kernel, and launches containers and pods as child processes. In addition, it was developed for the Docker developer, with most commands and syntax seamlessly mirroring Docker's. Buildah, an image builder, and Skopeo, the image utility... - Source: dev.to / almost 2 years ago
If you are curious about how exactly Docker does this I urge to have a look at the following links on layered file system and the library runc and also this great wikipedia overview of Docker. - Source: dev.to / almost 2 years ago

Docker Hub - Docker Hub is a cloud-based registry service
containerd - An industry-standard container runtime with an emphasis on simplicity, robustness and portability
Apache Thrift - An interface definition language and communication protocol for creating cross-language services.
Crane - Crane is a docker image builder to approach light-weight ML users who want to expand a container image with custom apt/conda/pip packages without writing any Dockerfile.
