Containerfile / Dockerfile generator library
Project Description
Writing container definition files is boring and error-prone: let's use power of a programming language to generate containers!
Project purpose:
- Experiment about container creation workflow and container management/publishing/versioning
- Play with a new non-mainstream programming language and show off capabilities/ease of usage. Ideally I plan to use nim, if time permits also experiment with others
- Follow Test-Driven Development (TDD) practices
- Have fun
Advantages:
- all features of a proper language: variables, multiline strings, logic statements, loops, code reuse.
- static syntax checking, no more typos or duplicate entries
- generate many docker files from one template [testing, production, ... ]
- generate sequence [Dockerfile.suse => Dockerfile.python => Dockerfile.yourapp, ...]
- could generate command line snippets or CI build scripts with the same data
- optimize container image creation removing redundant layers
Goal for this Hackweek
Preliminary study and make a proof of concept on a github repo with some working examples
Resources
- https://github.com/jen-soft/pydocker
- https://github.com/dahernan/godockerize
- https://www.mankier.com/5/Containerfile
Further ideas
- secret scan to avoid API key/tokens leaks
- optional "runtime" checking
- extend for multi_stage, docker compose
- import existing Dockerfile
- sanitize / check for issues ("linting")
- iterate on generation by extending to YAML format: k8s manifests, github workflows ...
Looking for hackers with the skills:

We are currently generating the Dockerfiles for the BCI images via python: https://github.com/SUSE/BCI-dockerfile-generator/tree/main/src/bci_build This is probably not what you are looking for, as it's really just a wrapper around jinja2 templates, but maybe it can help you out a bit.

Help Create A Chat Control Resistant Turnkey Chatmail/Deltachat Relay Stack - Rootless Podman Compose, OpenSUSE BCI, Hardened, & SELinux by 3nd5h1771fy
Description
The Mission: Decentralized & Sovereign Messaging
FYI: If you have never heard of "Chatmail", you can visit their site here, but simply put it can be thought of as the underlying protocol/platform decentralized messengers like DeltaChat use for their communications. Do not confuse it with the honeypot looking non-opensource paid for prodect with better seo that directs you to chatmailsecure(dot)com
In an era of increasing centralized surveillance by unaccountable bad actors (aka BigTech), "Chat Control," and the erosion of digital privacy, the need for sovereign communication infrastructure is critical. Chatmail is a pioneering initiative that bridges the gap between classic email and modern instant messaging, offering metadata-minimized, end-to-end encrypted (E2EE) communication that is interoperable and open.
However, unless you are a seasoned sysadmin, the current recommended deployment method of a Chatmail relay is rigid, fragile, difficult to properly secure, and effectively takes over the entire host the "relay" is deployed on.
Why This Matters
A simple, host agnostic, reproducible deployment lowers the entry cost for anyone wanting to run a privacy‑preserving, decentralized messaging relay. In an era of perpetually resurrected chat‑control legislation threats, EU digital‑sovereignty drives, and many dangers of using big‑tech messaging platforms (Apple iMessage, WhatsApp, FB Messenger, Instagram, SMS, Google Messages, etc...) for any type of communication, providing an easy‑to‑use alternative empowers:
- Censorship resistance - No single entity controls the relay; operators can spin up new nodes quickly.
- Surveillance mitigation - End‑to‑end OpenPGP encryption ensures relay operators never see plaintext.
- Digital sovereignty - Communities can host their own infrastructure under local jurisdiction, aligning with national data‑policy goals.
By turning the Chatmail relay into a plug‑and‑play container stack, we enable broader adoption, foster a resilient messaging fabric, and give developers, activists, and hobbyists a concrete tool to defend privacy online.
Goals
As I indicated earlier, this project aims to drastically simplify the deployment of Chatmail relay. By converting this architecture into a portable, containerized stack using Podman and OpenSUSE base container images, we can allow anyone to deploy their own censorship-resistant, privacy-preserving communications node in minutes.
Our goal for Hack Week: package every component into containers built on openSUSE/MicroOS base images, initially orchestrated with a single container-compose.yml (podman-compose compatible). The stack will:
- Run on any host that supports Podman (including optimizations and enhancements for SELinux‑enabled systems).
- Allow network decoupling by refactoring configurations to move from file-system constrained Unix sockets to internal TCP networking, allowing containers achieve stricter isolation.
- Utilize Enhanced Security with SELinux by using purpose built utilities such as udica we can quickly generate custom SELinux policies for the container stack, ensuring strict confinement superior to standard/typical Docker deployments.
- Allow the use of bind or remote mounted volumes for shared data (
/var/vmail, DKIM keys, TLS certs, etc.). - Replace the local DNS server requirement with a remote DNS‑provider API for DKIM/TXT record publishing.
By delivering a turnkey, host agnostic, reproducible deployment, we lower the barrier for individuals and small communities to launch their own chatmail relays, fostering a decentralized, censorship‑resistant messaging ecosystem that can serve DeltaChat users and/or future services adopting this protocol

Technical talks at universities by agamez
Description
This project aims to empower the next generation of tech professionals by offering hands-on workshops on containerization and Kubernetes, with a strong focus on open-source technologies. By providing practical experience with these cutting-edge tools and fostering a deep understanding of open-source principles, we aim to bridge the gap between academia and industry.
For now, the scope is limited to Spanish universities, since we already have the contacts and have started some conversations.
Goals
- Technical Skill Development: equip students with the fundamental knowledge and skills to build, deploy, and manage containerized applications using open-source tools like Kubernetes.
- Open-Source Mindset: foster a passion for open-source software, encouraging students to contribute to open-source projects and collaborate with the global developer community.
- Career Readiness: prepare students for industry-relevant roles by exposing them to real-world use cases, best practices, and open-source in companies.
Resources
- Instructors: experienced open-source professionals with deep knowledge of containerization and Kubernetes.
- SUSE Expertise: leverage SUSE's expertise in open-source technologies to provide insights into industry trends and best practices.
Rewrite Distrobox in go (POC) by fabriziosestito
Description
Rewriting Distrobox in Go.
Main benefits:
- Easier to maintain and to test
- Adapter pattern for different container backends (LXC, systemd-nspawn, etc.)
Goals
- Build a minimal starting point with core commands
- Keep the CLI interface compatible: existing users shouldn't notice any difference
- Use a clean Go architecture with adapters for different container backends
- Keep dependencies minimal and binary size small
- Benchmark against the original shell script
