"Continuous Delivery for a multi-tenant distributed System via GitlabCI and Helm"

By way of an experience report, we will present the transformation of a system with more than 50 microservices into a multi-tenant solution.
Originally intended for a single customer, many new software architecture and workflow requirements emerged.
We will introduce the service and feature categorization that we created in order to meet the challenges of a multi-tenant structure.
The main part of the talk will focus on the changes that took place in our infrastructure and build- and deploypipelines.
We pay particular attention to how GitlabCI, Helms Dependency Management and Chartmuseum interact with another and are used in an automated, seamless transition between development, stage, and production across multiple tenant environments, all of which require different sets of services.
