Crossplane @ Mastering GitOps.pdf
Mastering GitOps 2022, April, Mario-Leander Reimer (@LeanderReimer, Principal Software Architect bei QAware). == Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! == Crossplane or: kubectl apply -f cloud-Infrastructure-as-code.yaml Developing cloud-native applications easily and efficiently presents significant challenges for many teams. This is because, in addition to implementing domain-specific features and microservices, developers are now often jointly responsible for building the required cloud services with Infrastructure as Code à la Terraform. Unfortunately, the associated high cognitive load quickly leads to overload and suboptimal solutions. Crossplane is an open source add-on for Kubernetes that addresses this problem. Using Crossplane, one can declaratively build cloud infrastructure for all popular cloud providers without writing a line of code. In addition, there is the ability to create highly specific self-service APIs and abstractions that can then be applied very easily by feature teams. This talk will demonstrate the practical use of Crossplane with its features in AWS and GCP, as well as the seamless integration with a GitOps approach.

- 10. Crossplane in a Nutshell ■ https://crossplane.io ■ Open Source Kubernetes Add-on. Universal Control Plane for Cloud Infrastructure. ■ Plattform Teams können mittels Crossplane die Cloud Infrastruktur Dienste unterstützter Provider zusammenstellen und über High-Level Self-Service APIs bereitstellen. ■ Cloud Infrastruktur Dienste können von Anwendungs-Teams deklarativ definiert werden ■ Provider bündeln eine Menge an Managed Resources und den dazugehörigen Controller. Alle gängigen Cloud Provider werden unterstützt, e.g. AWS, GCP, Azure, Alibaba, … ■ Managed Resources sind granulare, hochgenaue Crossplane-Repräsentationen einer Ressource in einem externen System. ■ Composite Resource Definitionen oder XRDs ermöglichen die Definitionen neuer Abstraktionen für zusammengesetzte Managed Resources. ■ Configurations und Packages erlauben die einfache Definition, Verteilung und Aktualisierung von XRDs und deren Abhängigkeiten.
