Rancher Kubernetes Engine 2 Deployment
This course is dedicated to the deployment of Rancher Kubernetes Engine 2 (RKE2). You’ll start by learning the basics of installing RKE2, and then move on to installing a highly available RKE2 cluster. Next, we’ll dive into installing additional clusters with different configurations, including custom Kubernetes addons like Auto Deployment Service, advanced networking like the Multus CNI plugin, and CIS hardening. We will also explain how to install a cluster in an air-gapped environment. Once you have done the different cluster installations, you will be backing up and restoring an RKE2 cluster. Finally, you’ll learn how to upgrade standard and air-gapped RKE2 clusters.
COD: KUB211v1.24
CATEGORY: SUSE Rancher
Who should participate
This course is intended for SUSE Linux Enterprise administrators who have worked with previous versions; the main focus is the transition from SLE 12 to SLE 15.
Prerequisites
This course is intended for students with prior experience of SUSE Linux Enterprise Server equivalent to SLE201 SUSE Linux Enterprise Server 12 Administration, although intermediate experience with any Linux distribution will suffice.
Objectives of the Course
Participants will be introduced to the following SLE 15 innovations:
- Changes to installation and AutoYaST
- Infrastructure changes, including chrony and firewalld
- Changes to the core Linux kernel, OpenSSL and libstorage
- Developer changes: SDK, GCC7 and scripting languages
- Further changes to the operating system
- Upgrade to SLE 15 from previous versions
Participants will be taught the following concepts and skills:
- Deployment of RKE2 clusters, both standard high availability clusters and clusters with custom K8s addons, advanced networking and CIS hardening.
- Implementing RKE2 clusters in an air-gapped environment
- Backup and restore of RKE2 clusters
- Updating RKE2 clusters
