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

For documentation that is not specific to OpenShift Dedicated, see the OpenShift Container Platform documentation.

Developer activities

Ultimately, OpenShift Dedicated is a platform for developing and deploying containerized applications. As an application developer, this documentation helps you:

  • Understand OpenShift Dedicated 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 Dedicated 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 Dedicated concepts, allowing developers to focus on developing their applications.

  • Create CI/CD Pipelines: Pipelines are serverless, cloud-native, continuous integration and continuous deployment systems that run in isolated containers. They use standard Tekton custom resources to automate deployments and are designed for decentralized teams that work on microservices-based architecture.

  • Understand Operators: Operators are the preferred method for creating on-cluster applications for OpenShift Dedicated . 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 Dedicated (and Kubernetes) applications. Defining image streams 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: Use Deployment and DeploymentConfig objects to exert fine-grained management over applications. Use the Workloads page or oc CLI to manage deployments. 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.

Cluster administrator activities

While cluster maintenance and host configuration is performed by the Red Hat Site Reliability Engineering (SRE) team, other ongoing tasks on your OpenShift Dedicated cluster can be performed by OpenShift Dedicated cluster administrators. As an OpenShift Dedicated cluster administrator, the documentation helps you:

  • Manage Dedicated Administrators: Grant or revoke permissions to dedicated admin users.

  • Work with Logging: Learn about OpenShift Logging and configure the Cluster Logging Operator.

  • Monitor clusters: Learn to use the Web UI to access monitoring dashboards.

  • Manage nodes: Learn to manage nodes, including configuring machine pools and autoscaling.
