Deploying MicroShift on Red Hat Device Edge

Objective

This course teaches how to deploy and configure MicroShift on Red Hat Device Edge targets, using either traditional RHEL or RHEL for Edge, to support Kubernetes applications.

It is part of a Red Hat Device Learning path, which currently includes three courses in two different tracks:

For customers using RHEL for Edge and RPM-OSTree based edge images:
- Building Red Hat Device Edge Images (prerequisite course)
- Deploying MicroShift on Red Hat Device Edge (this course)
For customers using RHEL image mode:
- Deploying MicroShift on RHEL Image Mode

Red Hat employees must enroll using its LMS entry to get completion credits, and Red Hat Partners must enroll using its Partner Portal entry.

Audience

Operations-focused customer roles, who design and implement device edge images, but are not usually in-person at edge sites:

System Administrators (IT - Information Technology, and OT - Operations Technology)
Site Reliability Engineers (SREs)
Platform Engineers
DevOps Engineers

Red Hat and Partner roles that perform demonstrations, PoC and PoV of Red Hat Device Edge as part of a sales motion, such as Solutions Architects

Red Hat and Partner roles that support Red Hat Device Edge on customers, such as Services Consultants and Customer Support Engineers.

Prerequisites

Attend RHDE-1: Building Red Hat Device Edge Images or having equivalent experience with RHEL for Edge.
Familiarity with RHEL system administration, to the level of Red Hat Certified System Administrator (RHCSA) or equivalent knowledge.
Familiarity with OpenShift administration, to the level of Red Hat Certified OpenShift Administrator or equivalent knowledge.
Familiarity with Ansible playbooks and the Ansible Automation Platform is useful but not required.
Familiarity with web server administration, such as Apache Web Server or NGinx, is useful but not required.
Familiarity with database server administration, such as MySQL or MariaDB, is useful but not required.

Classroom Environment

You can perform all activities in this course using the virtual classroom lab from HOL014: Red Hat Device Edge Quick Course Series, which is shared by all Red Hat Device Edge quick courses and will be updated as required by future related courses.

Use the following links to access the virtual classroom lab on Red Hat Online Learning (ROLE):

HOL014 for Red Hat employees.
HOL014 for Red Hat partners and customers with a Red Hat Learning Subscription.

After you enter HOL014 on ROLE, follow the instructions there to create a new course classroom lab and access its virtual machines. If you already created a HOL014 classroom for another Red Hat Device Edge quick course, you can continue using the same classroom lab.

Beware that ROLE classrooms have timers after which classroom labs are stopped and deleted, to conserve compute resources. If you plan to use the same classroom lab for multiple Red Hat Device Edge quick courses, do not wait too long to continue. You do not need to use the same classroom for multiple courses: each course provides step-by-step instructions to start from either a new classroom lab or to continue from an existing classroom lab.

You will follow this quick course by alternating between two browser windows: one to navigate quick course materials, such as this page; and another to access the virtual classroom lab, to perform hands-on activities.

If you can provision your own RHEL servers or VMs, it should be possible to configure all that is required for the hands-on activities by using a free subscription from the Red Hat Developer Program, which gives access to RHEL installation media, RHEL package repositories, OpenShift package repositories, and OpenShift container images in Red Hat registries.

About Red Hat Online Learning (ROLE) and Red Hat Learning Subscription

The Red Hat Online Learning (ROLE) web site provides Red Hat Training and Certification course materials and their virtual classrooms labs. You must be enrolled in a Red Hat Training course or subscription to have access to ROLE.

The Red Hat Device Edge Quick Courses Series use ROLE for its virtual classroom labs only, and hosts courses materials outside of ROLE, as GitHub pages.

A basic Red Hat Learning Subscription offers access to a number Red Hat Training courses and virtual classroom lab time. Higher subscription tiers offer additional benefits such as Red Hat Certification Exam vouchers.

Other Sources of Information About MicroShift

The main source is the product documentation for MicroShift in Red Hat’s documentation portal.

We also recommend that you use the product documentation for Red Hat OpenShift Container Platform for general Kubernetes topics, OpenShift extension APIs, and add-on operators which may be supported in MicroShift.

The Red Hat Build of MicroShift is supported as part of Red Hat Device Edge, check its overview document for pointers to MicroShift, RHEL for Edge, and other components of Red Hat Device Edge, in particular the documentation about Composing, installing, and managing RHEL for Edge images.

It is not expected that you need to use the open source upstream of MicroShift and its community documentation for day to day use of the Red Hat Build of MicroShift.

Special thanks to Gregory Giguashvili and Vladislav Walek for all their support while writing this course and testing its hands-on activities.

Many thanks to Daniel Froehlich for his support in reviewing the course design, its outline, work-in-progress contents, and answering my newbie questions, and also to Eric Lavarde for reviews and feedback during course development.
