Testing applications with traffic control in containers DevOps и эксплуатация
Originally from France, Alban currently lives in Berlin where he is a co-founder and software engineer at Kinvolk GmbH. He is a core contributor to rkt, a container runtime for Linux. Before falling into containers, Alban worked on various projects core to modern Linux; kernel IPC and storage, dbus performance and security, etc. His current technical interests revolve around networking, security, systemd and containers at the lower-levels of the system.

Testing applications is important, as shows the rise of continuous integration and automated testing. In this talk, I will focus on one area of testing that is difficult to automate: poor network connectivity. Developers usually work within reliable networking conditions so they might not notice issues that arise in other networking conditions. I will give examples of software that would benefit from test scenarios with varying connectivity. I will explain how traffic control on Linux can help to simulate various network connectivity. Finally, I will run a demo showing how an application running in Kubernetes behaves when changing network parameters.
