Developer activities

Ultimately, OpenShift is a platform for developing and deploying containerized applications. As an application developer, OpenShift Container Platform documentation will help you:

  • Understand OpenShift Container Platform 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.

  • Understand Operators: Operators are the preferred method for creating on-cluster applications for OpenShift Container Platform 4.1. 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 (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.

  • Create Operators: Operators are the preferred method for creating on-cluster applications for OpenShift Container Platform 4.1. Learn the workflow for building, testing, and deploying Operators. Then create your own Operators based on Ansible or Helm, or configure built-in Prometheus monitoring using the Operator SDK.

  • Use Template Service Broker or OpenShift Ansible Broker applications: Service brokers are a mechanism for provisioning applications outside of an OpenShift Container Platform environment.

Cluster administrator activities

Ongoing tasks on your OpenShift Container Platform 4.1 cluster include various activities for managing machines, providing services to users, and following monitoring and logging features that watch over the cluster. As a cluster administrator, this documentation will help you:
