Containerization and microservices architecture have become foundational in modern software development and operations. Gartner predicts that by 2026, over 90% of global organizations will be running containerized applications in production, up from less than 40% in 2021. This shift brings both opportunities and complexity for enterprise IT.
In this deployment guide, we will be effortlessly installing the core Rancher Stack, including Rancher Kubernetes, Rancher Multi-Cluster Manger, Longhorn, and NeuVector. In about 15 minutes, we will have a three-node Kubernetes Cluster (RKE2), with lifecycle management (Rancher Manager), persistent storage (Longhorn), and cluster security (NeuVector).
As a new engineer at Rancher Federal (Suse Rancher Government Solutions) I wanted to setup Keycloak with TLS Passthrough on my shinny new RKE2 cluster. For the uninitiated TLS Passthrough is a way for the ingress or proxy to all TLS to passthrough. Meaning the pod itself will terminate TLS and not the ingress/proxy. RKE2 is fantastic that it ships with Nginx Ingress. There are a few other options out there on the market for ingress. Another favorite is Traeifk. But for this cluster I wanted to use the built in pieces. Nginx it is!
To the uninitiated, Kubernetes does a fairly simple thing: it provides the scaffolding to effortlessly run applications with very complex architectures. Rancher has built on top of this scaffolding, making it easy not only to deploy and manage Kubernetes clusters but also applications. With Kubernetes, a lot of established paradigms of software development are evolving, oftentimes forcing many structural changes for the organizations. Things that many IT and procurement departments started to take for granted with the adoption of Infrastructure as a Service (IaaS), like cost allocation, get a new meaning and new complexity with Kubernetes.
