Singularity Container VS Buildah

I highly recommend checking out Singularity for your computational software. Running your software within containers allows you a lot of freedom, although it does create some complexity in regards to MPI based parallelization. Source: almost 2 years ago

Use a singularity image to contain what you want to deploy and give access on the jump host to the image. Permissions flow from existing OS permissions. https://sylabs.io/singularity/. Source: over 2 years ago

Singularity This is a HPC focused container system that has large industry support. You can use this to package finicky software that only runs on specific linux distributions or only allows for RPM/Deb installations. It is also another mechanism for users to bring their own software and it integrates fairly well with both Slurm and HTCondor. Source: over 2 years ago

> and it was then when they came up with a pretty cool name for their new OS — Singularity. Or, it was then when they (intentionally?) ripped off the name of an existing, open source, OS-related project. https://sylabs.io/singularity/. - Source: Hacker News / over 2 years ago

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. Source: over 1 year ago
