You can start with an Introduction to OpenShift Online.
Ultimately, OpenShift Online is a platform for developing and deploying containerized applications. As an application developer, OpenShift Online documentation will help you:
Understand OpenShift Online development: Learn the different types of containerized applications, from simple containers to advanced Kubernetes deployments and Operators.
Work with projects: Create projects from the web console or CLI to organize and share the software you develop.
Work with applications: Use the Developer perspective in the OpenShift Online web console to easily create and deploy applications. Use the Topology view to visually interact with your applications, monitor status, connect and group components, and modify your code base.
Use the developer CLI tool (odo): The odo CLI tool lets developers create single or multi-component applications easily and automates deployment, build, and service route configurations. It abstracts complex Kubernetes and OpenShift Online concepts, allowing developers to focus on developing their applications.
Understand Operators: Operators are the preferred method for creating on-cluster applications for OpenShift Online Starter. Learn about the Operator Framework and how to deploy applications using installed Operators into your projects.
Understand image builds: Choose from different build strategies (Docker, S2I, custom, and pipeline) that can include different kinds of source materials (from places like Git repositories, local binary inputs, and external artifacts). Then, follow examples of build types from basic builds to advanced builds.
Create container images: A container image is the most basic building block in OpenShift Online (and Kubernetes) applications. Defining imagestreams lets you gather multiple versions of an image in one place as you continue its development. S2I containers let you insert your source code into a base container that is set up to run code of a particular type (such as Ruby, Node.js, or Python).
Create Deployments and DeploymentConfigs: Use Deployments and DeploymentConfigs to exert fine-grained management over applications.
Use the Workloads page or
oc CLI to manage DeploymentConfigs. Learn Rolling, Recreate, and Custom deployment strategies.
Create templates: Use existing templates or create your own templates that describe how an application is built or deployed. A template can combine images with descriptions, parameters, replicas, exposed ports and other content that defines how an application can be run or built.
