¿Qué tal gente? ¿Preparados para el cambio de hora? Pues a mi me tenéis escuchando un pupurri de música, mientras estoy montando un #Dockerfile para pasar un proyecto a este formato. Unos salen de discoteca y otros nos quedamos jugando con contenedores #Docker

Some rules to apply to your Dockerfile in order to make your Docker image more reproducible :

- do not use "latest" versions of base images
- use official images pulled from the official Docker library
- pin versions in pip/apt/npm/yum... install (no apt-update)
- clean temporary files (apt-get clean, rm -rf /var/lib/apt/lists/*, etc.)

Docker Does Not Guarantee Reproducibility

The reproducibility of software environments is a critical concern in modern software engineering, with ramifications ranging from the effectiveness of collaboration workflows to software supply chain security and scientific reproducibility. Containerization technologies like Docker address this problem by encapsulating software environments into shareable filesystem snapshots known as images. While Docker is frequently cited in the literature as a tool that enables reproducibility in theory, the extent of its guarantees and limitations in practice remains under-explored. In this work, we address this gap through two complementary approaches. First, we conduct a systematic literature review to examine how Docker is framed in scientific discourse on reproducibility and to identify documented best practices for writing Dockerfiles enabling reproducible image building. Then, we perform a large-scale empirical study of 5298 Docker builds collected from GitHub workflows. By rebuilding these images and comparing the results with their historical counterparts, we assess the real reproducibility of Docker images and evaluate the effectiveness of the best practices identified in the literature.

De manière assez convaincante bien que sur un échantillon restreint (5 articles de conférence), une étude récente montre que le fait de fournir le code source avec un #dockerfile pour en obtenir une image Docker échoue à garantir une reproductibilité des résultats en quelques mois. En chargeant les dernières versions de paquets issus de gestionnaires qui sont en soi non reproductibles, cette "recette" ne peut construire que des images qui varient assez vite avec le temps https://dl.acm.org/doi/10.1145/3736731.3746146

Кэш-монтирование или Cache mount в Docker. Использование кэш-монтирования в GitLab CI/CD

Кэш-монтирование в Docker — это мощный инструмент, который может значительно ускорить процесс сборки образов в CI/CD. Но его правильная настройка в GitLab требует понимания не только работы BuildKit, но и особенностей взаимодействия с различными конфигурациями GitLab Runner — DinD и DooD. В этой статье я расскажу об устройстве кэш-монтирования в Docker и как его использовать в GitLab CI/CD. На примере простой сборки Python-проекта покажу готовые решения для кэширования зависимостей, чтобы оптимизировать сборку Docker-образов.

I might be a few months late, but I finally found some time to publish my "magnetic_tape" crypto challenge from #NullCon #Berlin #HackIM #CTF 2025:

https://github.com/OOTS/magnetic_tape

I included the source code (was published anyway during the CTF), my own solution, my own #writeup, and some internal files (#Dockerfile, docker-compose, minimal #python #unittests).

Also: #NullCon #Goa #HackIM #CTF 2026 is happening in a few days: https://ctf.nullcon.net
Go check it out!

And the #rpm from #dockerfile builder called roci is on GitHub as well: https://github.com/dcermak/roci

Poprosiłem Copilota o zoptymalizowanie mojego Dockerfile, który służy do budowania aplikacji. Przed zmianami budował się do 2GB, po "optymalizacji" miał 2.1GB. I takie to z AI zabawy xD
