Overview of this book

For IT professionals working with Red Hat OpenShift Container Platform, the key to maximizing efficiency is understanding the powerful and resilient options to maintain the software development platform with minimal effort. OpenShift Multi-Cluster Management Handbook is a deep dive into the technology, containing knowledge essential for anyone who wants to work with OpenShift. This book starts by covering the architectural concepts and definitions necessary for deploying OpenShift clusters. It then takes you through designing Red Hat OpenShift for hybrid and multi-cloud infrastructure, showing you different approaches for multiple environments (from on-premises to cloud providers). As you advance, you’ll learn container security strategies to protect pipelines, data, and infrastructure on each layer. You’ll also discover tips for critical decision making once you understand the importance of designing a comprehensive project considering all aspects of an architecture that will allow the solution to scale as your application requires. By the end of this OpenShift book, you’ll know how to design a comprehensive Red Hat OpenShift cluster architecture, deploy it, and effectively manage your enterprise-grade clusters and other critical components using tools in OpenShift Plus.

Vulnerability management

There is a general consensus that any system has vulnerabilities; some of them are known and some are not identified yet. Vulnerability management is the process of identifying and managing known vulnerabilities, which means having plans in place to remediate or mitigate the impact of the vulnerabilities. Navigate to Vulnerability Management | Dashboard to see what this feature looks like:

Figure 12.31 – Vulnerability management

Through this feature, you can walk through all the vulnerabilities detected by ACS and decide what actions to take:

  • Remediate the vulnerability either by removing the vulnerable software package from the application or updating it with a more recent version in which the vulnerability is already fixed.
  • Accept the risk.
  • Mark it as a false positive.

Vulnerabilities are detected and grouped in terms of the following:

  • Components: Software packages used by containers. This group...
