During Summer Hackdays 2022, I worked on a project called “Zeebe chaos” (zbchaos), a fault injection command-line interface (CLI) tool. This allows us engineers to more easily run chaos experiments against Zeebe, build up confidence in the system’s capabilities, and discover potential weaknesses. Requirements To understand this blog post, it is useful to have a certain understanding of Kubernetes and Zeebe itself. Summer Hackdays: Hackdays are a regular event at Camunda, where people from different departments (engineering, consulting, DevRel, etc.) work together on new ideas, pet projects, and more. Check out previous Summer Hackdays here: Summer Hackdays 2020 Summer Hackdays 2019 Zeebe chaos CLI Working on the Zeebe project is not only about engineering a distributed system or a process...

Dive into the detailed learnings and experiences from our journey to find a sufficient way to write automated tests for Helm charts.

Introduction On the new version of the Camunda Engine Platform (7.7) the user passwords, which are stored in the database, are by default hashed with a SHA-2 family algorithm. Before the passwords are hashed, they are concated with an individual random generated salt for each user, to prevent dictionary and rainbow table attacks. For someone who needs a more secure hashing algorithm Camunda introduce a new API, which allows to customize and exchange the default hashing algorithm. In this blog post I will present this customization and will use argon2 as hashing algorithm. Argon2 is a password-hashing function 1, which is considered as state of the art and also won the Password Hashing Competition at the end of 2015 2....
