Chapter 3. Getting support


To resolve issues with your OpenShift Container Platform cluster, you can search the Red Hat Knowledgebase, submit a support case, and use remote health monitoring tools.

3.1. Getting support

Red Hat offers several support channels to help you troubleshoot issues and get the most from OpenShift Container Platform.

From the Red Hat Customer Portal, you can:

  • Search or browse through the Red Hat Knowledgebase of articles and solutions about Red Hat products.
  • Submit a support case to Red Hat Support.
  • Access other product documentation.

To identify issues with your cluster, you can use Red Hat Lightspeed in OpenShift Cluster Manager. Red Hat Lightspeed provides details about issues and, if available, information about how to solve a problem.

To suggest improvements or report errors, give specific details such as the section name and OpenShift Container Platform version.

3.2. About the Red Hat Knowledgebase

The Red Hat Knowledgebase helps you get the most from Red Hat products and technologies.

It includes articles, product documentation, and videos that outline best practices for installing, configuring, and using Red Hat products. You can also search for solutions to known issues. Each solution has a root cause description and steps to fix the problem.
