1 points · Open discussionContainers are bloated. We built a runtime tool to remove bloat and CVEs
4 points · Open discussionWe are a bunch of academics who have worked on debloating tools for containers and we just released our code with an MIT license to Github: https://github.com/negativa-ai/BLAFS
A full description of the work is here: https://arxiv.org/abs/2305.04641
We have tested the tool on many containers. For the top 20 pulled docker containers, the savings are up to 95% with all the containers working. We have done the same tests with slim-toolkit and it was only able to debloat 8 out of 20. We are looking at making this more automated for users.
Now, we only support docker, but we are working on podman and lXCs. We are also working on a version that guarantees generality (i.e., we give you 100% guarantees that your container will always work) with zero requirements to profile.
Please do try it and let us know what you think! All feedback is welcome!
In Containers are bloated. We built a runtime tool to remove bloat and CVEsShow HN: We have just released our first Debloating tool for Containers
We have been working on tools for safe debloating of software for a few years now at the university. BLAFS is one of our first tools to release for file debloating, a bloat-aware filesystem for container debloating. It detects the files used by the container, and the debloats the container removing the unused files. The debloated containers are fully functional and can run the same workload as the original containers, but with a much smaller size and faster deployment.
