Chapter 2. Installing CodeReady Workspaces on OpenShift 3 using the Operator
Operators are a method of packaging, deploying, and managing a OpenShift application which also provide the following:
- Repeatability of installation and upgrade.
- Constant health checks of every system component.
- Over-the-air (OTA) updates for OpenShift components and ISV content.
- A place to encapsulate knowledge from field engineers and spread it to all users.
This chapter describes how to install CodeReady Workspaces on OpenShift 3 using the CLI management tool and the Operator method.
2.1. Installing CodeReady Workspaces on OpenShift 3 using the Operator
This section describes how to install CodeReady Workspaces on OpenShift 3 with the CLI management tool to install via the Operator with SSL (HTTPS) enabled.
