OpenShift Container Platform 4.13

Introduction to OpenShift Container Platform

Red Hat OpenShift Documentation Team


This document provides an overview of the OpenShift Container Platform features.

Chapter 1. OpenShift Container Platform 4.13 Documentation

Welcome to the official OpenShift Container Platform 4.13 documentation, where you can learn about OpenShift Container Platform and start exploring its features.

To navigate the OpenShift Container Platform 4.13 documentation, you can use one of the following methods:

  • Use the left navigation bar to browse the documentation.
  • Select the task that interests you from the contents of this Welcome page.

Start with Architecture and Security and compliance. Next, view the release notes.

1.1. Cluster installer activities

Explore the following OpenShift Container Platform installation tasks:

1.2. Developer activities

Develop and deploy containerized applications with OpenShift Container Platform. OpenShift Container Platform is a platform for developing and deploying containerized applications. OpenShift Container Platform documentation helps 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 OpenShift Container Platform web console or OpenShift CLI (oc) to organize and share the software you develop.
  • Work with applications.
  • Use the Developer perspective in the OpenShift Container Platform web console to create and deploy applications.
  • Use the Topology view to see your applications, monitor status, connect and group components, and modify your code base.
  • Connect your workloads to backing services: With the Service Binding Operator, an application developer can bind workloads with Operator-managed backing services by automatically collecting and sharing binding data with the workloads. The Service Binding Operator improves the development lifecycle with a consistent and declarative service binding method that prevents discrepancies in cluster environments.
  • Create CI/CD Pipelines: Pipelines are serverless, cloud-native, continuous integration and continuous deployment systems that run in isolated containers. Pipelines use standard Tekton custom resources to automate deployments and are designed for decentralized teams that work on microservice-based architecture.
  • Manage your infrastructure and application configurations: GitOps is a declarative way to implement continuous deployment for cloud native applications. GitOps defines infrastructure and application definitions as code. GitOps uses this code to manage multiple workspaces and clusters to simplify the creation of infrastructure and application configurations. GitOps also handles and automates complex deployments at a fast pace, which saves time during deployment and release cycles.
  • Deploy Helm charts: Helm is a software package manager that simplifies deployment of applications and services to OpenShift Container Platform clusters. Helm uses a packaging format called charts. A Helm chart is a collection of files that describes the OpenShift Container Platform resources.
  • Understand image builds: Choose from different build strategies (Docker, S2I, custom, and pipeline) that can include different kinds of source materials, such as Git repositories, local binary inputs, and external artifacts. You can 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 Container Platform and Kubernetes applications. By defining image streams, you can gather multiple versions of an image in one place as you continue to develop the image stream. With S2I containers, you can insert your source code into a base container. The base container is configured to run code of a particular type, such as Ruby, Node.js, or Python.
  • Create deployments: Use Deployment and DeploymentConfig objects to exert fine-grained management over applications. Manage deployments by using the Workloads page or OpenShift CLI (oc). 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.
  • Understand Operators: Operators are the preferred method for creating on-cluster applications for OpenShift Container Platform 4.13. Learn about the Operator Framework and how to deploy applications by using installed Operators into your projects.
  • Develop Operators: Operators are the preferred method for creating on-cluster applications for OpenShift Container Platform 4.13. Learn the workflow for building, testing, and deploying Operators. You can then create your own Operators based on Ansible or Helm, or configure built-in Prometheus monitoring by using the Operator SDK.
  • REST API reference: Learn about OpenShift Container Platform application programming interface endpoints.

1.3. Cluster administrator activities

Manage machines, provide services to users, and follow monitoring and logging reports. This documentation helps you:

1.3.1. Manage cluster components

1.3.2. Change cluster components

1.3.3. Monitor the cluster

  • Work with OpenShift Logging: Learn about OpenShift Logging and configure different OpenShift Logging types, such as Elasticsearch, Fluentd, and Kibana.
  • Red Hat OpenShift distributed tracing platform: Store and visualize large volumes of requests passing through distributed systems, across the whole stack of microservices, and under heavy loads. Use the distributed tracing platform for monitoring distributed transactions, gathering insights into your instrumented services, network profiling, performance and latency optimization, root cause analysis, and troubleshooting the interaction between components in modern cloud-native microservices-based applications.
