A large part of modern security practices around container images is crafting minimal runtime environments.
To put it plainly, developers are asking: “how little can we put into the container, and make it still do the thing we want it to do?” The process of building such minimal containers is a fascinating exploration of the way directory entry software components work and fit together.
In this talk, Marcin Konowalczyk explores how Rust toolchain works, how we build our hardened Rust images at Canonical, and what lies beyond.
About Marcin
By training Marcin Konowalczyk is a chemist, but by passion he is a Software Engineer. During his academic years, he found a niche in programming custom machines and data analysis pipelines. He has never had a good head for complex maths, so writing little programs and simulations turned out to be his way into understanding more theoretical subjects.
Following his interest in programming, he has gone on to work as a Data Scientist, and then as Systems/Data Engineer. His main programming languages are Python and Go, but he has engaged in a few fights with the (in)famous borrow checker. On a hobbyist front, he is particularly interested in programming language design and computational art. His favourite algorithm is the unconstrained optimization using a simplex method.
