    SUSE Course LHN201v1.5 – Longhorn Deployment and Operations

    LHN201v1.5

    Opis

    This course is for system administrators responsible for deploying and managing Longhorn across various Kubernetes cluster distributions with Rancher Manager for Rancher Prime. The course kicks off with an introduction to Longhorn and its architecture, followed by practical lessons on accessing Longhorn through a simple web browser. Students will gain hands-on experience in deploying, managing, and upgrading Longhorn on their Kubernetes clusters.
    The course delves into volume management, creating volume replicas from persistent volumes using storage classes. It emphasizes the establishment of data replication for enhanced fault tolerance and data redundancy within the existing Kubernetes cluster.
    Additionally, students will learn the ins and outs of conducting scheduled snapshots, backups, and setting up a Disaster Recovery Volume.
    This course prepares students for the SCA in Longhorn Deployment and Operations exam once released.
