About
As Kubernetes gains adoption, teams are finding they must deploy and manage multiple clusters to facilitate features like geo-redundancy, scale, and fault isolation for their applications. With Submariner, your applications and services can span multiple cloud providers, data centers, and regions. The Broker must be deployed on a single Kubernetes cluster. This cluster’s API server must be reachable by all Kubernetes clusters connected by Submariner. It can be a dedicated cluster, or one of the connected clusters. Once Submariner is deployed on a cluster with the proper credentials to the Broker it will exchange Cluster and Endpoint objects with other clusters (via push/pull/watching), and start forming connections and routes to other clusters. Worker node IPs on all connected clusters must be outside of the Pod/Service CIDR ranges.

About
SudoRank is a hands-on practice platform where DevOps engineers, SREs, and sysadmins fix real broken systems on live Linux VMs and Kubernetes clusters. Not simulations, not containers.
750 challenges across 15 tracks: Linux, sysadmin, storage, scripting, networking, web servers, VPNs, Docker, Kubernetes, Terraform/Ansible, CI/CD, GitOps, server hardening, incident response, and offensive security.
Each challenge presents a broken environment with root access. Fix it however you want. Auto-grading checks actual system state, not the method.
Features: real multi-node K8s clusters, AI tutor that reads your terminal in real-time, progressive hints, interview prep, incident simulations, session recording, badges, and leaderboards.
Free: 8 tracks, 281 challenges. Pro ($8/mo): 13 tracks, 652 challenges. Pro+ ($15/mo): all 750 challenges plus unlimited AI tutor.
