With CentOS Linux 7 reaching end of life on June 30, 2024, organizations running CentOS Linux must migrate to a new operating system to continue receiving updates, security patches, and new features. To ease your migration from CentOS Linux to Red Hat Enterprise Linux, we've created additional resources to prepare new and existing customers for a seamless migration.
Red Hat Enterprise Linux (RHEL) 7 will reach end of maintenance support on June 30, 2024, hence it is important for our existing and new customers to plan their upgrade activities to the latest versions of RHEL. Customers have indicated the importance that upgrading is not stressful or disruptive. As a result, Red Hat has developed resources, tools, and consulting offerings needed for customers to keep their systems running.
Lab access for Red Hat training courses* that include a virtual training environment or associated lab has been extended to 45 days after the end date of the class. This change is directly related to feedback from students that old lab timeframe (not defined, typically cut off within a week) was too short to further develop skills from courses. *There are a few courses the extension doesn't apply to which are outlined in the linked blog.
Red Hat customers and partners have been asking for two-factor authentication. Red Hat has delivered the ability for customer organization administrators to require two-factor authorization—a widely accepted and industry standard to provide an additional layer of security along with passwords—for all users in their organization.
All technical documentation on the Red Hat Customer Portal recently received a facelift based on customer feedback. Notable areas of improvement include improved readability, accessibility, responsiveness, and interactivity.
The Partner Enablement team has kicked off several initiatives to improve the Partner Training Portal based on responses from this year’s Partner Training Portal Annual Survey. Improvement initiatives include a new homepage design, an onboarding welcome email, and a review of content tagging. All enhancements are driven by partner feedback and will make it easier for partners to find the enablement they need.
Customers have expressed how critical it is that Red Hat understands and prioritizes their support cases based on business impact. To better understand this, customers can now indicate business impact while creating a support case, when requesting an escalation, and when updating the severity of a case. A question has also been added to the Customer Effort Score (CES) survey that allows customers to indicate whether or not they felt that the technical engineer understood the business impact of their case once closed.
Red Hat OpenShift Container Platform customers requested an action-oriented, guided experience for new users to get started with OpenShift using the web console and the CLI. As a result, a new document was created that includes definitions for common terms found in Kubernetes and OpenShift Container Platform. The documentation also contains a walkthrough of the OpenShift Container Platform web console, as well as tips for creating and building applications by using the command-line interface.
Customers were looking for additional guidance on how to extend Prometheus metrics monitoring in KIE Server in our Red Hat Process Automation Manager (RHPAM) documentation. Given that the steps for setting it up can be slightly different in OpenShift, our Red Hat product documentation team added in additional steps to our RHPAM 7.11 documents.
The release of Red Hat Satellite 6.9 has improved the upgrade process for Red Hat Enterprise Linux (RHEL). Leapp upgrades can now be applied to the clients of the Satellite infrastructure. The Red Hat Support team identified the major pain points that customers experienced with their Leapp upgrade and provided information on how to address them in the linked blog.
With multiple Red Hat Ansible Tower versions available, customers faced issues finding and selecting the correct documentation for their version. To improve ease of navigation, a drop-down version selector menu has been added to Red Hat Ansible Tower documentation. This eliminates the need for customers to manually update the version number in their URL and makes relevant resources available with the click of a finger.
With the release of Red Hat Satellite 6.9, the process of registering a client system has been simplified by incorporating the global registration template. Registration is now easier, more secure, customizable, and has fewer steps. Prior to the release, Red Hat Support worked to identify major pain points customers may have with the registration process and created additional knowledge articles to assist customers with troubleshooting. These articles will help customers resolve their issues quickly and without having to open a support ticket.
Convert2RHEL is now an officially supported component of Red Hat Enterprise Linux (RHEL). Historically, Convert2RHEL was a self-support or consulting-supported utility. The tool allows users of RHEL derivatives, like CentOS, to convert their systems to fully supported RHEL machines. This will allow customers to easily migrate to stable and secure RHEL systems, while retaining existing applications and configurations.
Customers requested more end-to-end content and better findability in Red Hat OpenShift Container Platform documentation. In the 4.7 release, the Red Hat product documentation team added planning content to direct users to their best installation path. We also improved the Amazon Web Services (AWS) guidance by adding more planning details, verifications steps, and post-installation content. To improve findability, we added a page that highlights useful content based on user job roles.
A frequent concern raised by almost all our customers and partners is the validity of vulnerability scans and back-and-forth discussions around so called "false positives" in these scan reports. The validation and remediation of security vulnerabilities is a critical business function. The Red Hat product security team worked with our partners to improve the accuracy of vulnerability scans and have established a scanner certification to help ensure that accuracy and consistency across certified partners.
Red Hat recently (re)introduced "no-cost RHEL for small production workloads" and "no-cost RHEL for customer development teams." Red Hat has had no-cost RHEL programs for a long time, but it was limited to single-machine developers. Now, that has been expanded and it can be deployed in production on up to 16 systems. It is a completely self-supported new offering and should help users affected by the CentOS stream changes.
Customers told us there were too many obstacles to be successful while trying out Red Hat OpenShift. To ensure customers are on the right track in their "try it" journey, we reassessed the best ways to get started with the product. As a result, the OpenShift Try page was created as a one-stop shop to provide a guided "getting started" experience.
A non-sighted customer using a screen reader was unable to complete his OpenShift task due to incomplete accessibility support within a dropdown component within the product. The reader activated the dropdown, sourced from PatternFly (Red Hat's open source design system), but the component didn't shift focus into its items, preventing proper data presentation. Based on that customer interaction, PatternFly and Red Hat solved this accessibility issue, fixing it in turn for OpenShift and other platforms that use the component.
Customers have asked for Customer Portal content improvements ranging from findability to presentation and more end-to-end content. In response, we’ve announced a pilot for a subset of Red Hat Enterprise Linux documentation including new functionality, such as: more portable content that can be flexibly combined into different formats and documents, enhancements to both search on the Customer Portal and external search engine optimization, content that follows end-to-end user workflows, and more. Check back as we enhance this pilot effort and enable a more flexible customer content experience overall.
The Red Hat Certification team released hosted Red Hat Certification (rhcert), an officially supported interface for Red Hat partners to offer increased visibility and access to their product certifications. The result of feedback from a varied set of partners during a journey mapping exercise, this hosted solution lowers the barrier to entry for non-testers within the partner organizations who don’t necessarily need to execute tests but only wish to monitor certifications.
Cloud-init is an important component of a number of Red Hat cloud offerings, including Red Hat OpenStack Platform, Red Hat Virtualization, and Red Hat CloudForms. While documentation on configuring and using this tool as a component of these products is available, customers often requested a more complete reference that describes settings and usage. In response to this feedback, the Red Hat Enterprise Linux documentation team created a full reference and usage guide.
Due to some changes in previous versions of the product, documentation on upgrading and updating disconnected Satellites was not as detailed compared to the use cases for connected Satellites. After hearing concerns from customers with primarily disconnected set-ups, we added detailed instructions on upgrading and updating disconnected Satellites to the product documentation.
We are pleased to announce the availability of the new Technology Partner Success Desk (T-PSD), a free service where our technology partners can ask questions pertaining to Red Hat offerings, partner programs, product certification, engagement process, and more. Whether you are an existing Red Hat Partner using our products and technologies to build and certify for, support, and/or to interoperate with our platforms or are a prospective partner, use this service to ask questions throughout your journey. We’re providing this service to simplify the Red Hat partnering experience with the goal of achieving stronger relationships.
The Red Hat Product Security implemented a feedback loop for security flaws to address customer situations where the difference between Red Hat and NVD assigned CVSS scores is large. As a result of this CVSS re-score process with NVD, our customers now have a better understanding of the impact and risks associated with security issues.
The Red Hat OpenShift User Experience Design team gathered feedback from product users about search page functions in the console user interface and used that input to launch big enhancements to the search experience. Specifically, a "supercharged" multi-resource search has been added to OpenShift 4.4 to allow users to view multiple resources at a time and apply filters across different resource types at once.
Over the course of several months, the Red Hat User Experience Design team engaged with product users to collect input on the Topology View in Red Hat OpenShift. The team used that input to make eight substantial improvements to the Topology View experience in OpenShift 4.4.

As a result of customer feedback, the Red Hat Enterprise Linux documentation team learned that changing and resetting the root password is an important use case that should be documented in greater detail. Therefore, we have improved the documentation to provide procedures for changing and resetting the root password for various types of users (root/non-root) and under different circumstances.
The search team has added two new features to reduce the number queries resulting in 0 results and help our users find answers more easily. The "Did you mean?" feature focuses on misspellings and redirects users to the intended content. Related searches provides examples of more specific queries when users enter one word or low intent keywords or phrases, leading to richer result sets.
These two reference manuals were discontinued several releases ago, but customers continued to request them and highlight how important the information was to them. We created automation to pull the information directly from the software to compile the manual content. With a little bit of manual editing, the books are more up to date and current now than they were in the past.
Past flow matrix tables for Red Hat OpenStack Platform were not as complete and comprehensive as customers wanted. A combined effort with customer partners verified the desired format and data, and then Red Hat internal teams compiled all the data for all services to successfully deliver the matrix customers have wanted.
Red Hat OpenShift Container Storage customers requested clarity regarding architecture, supported configurations, infrastructure/software requirements, and sizing/scaling recommendations prior to deploying the product. In response, we delivered a new "Planning your deployment" document for the OCS 4.2 release to resolve planning-related questions and help prevent post-deployment issues due to insufficient pre-requisite information.
This newly added document provides sought-after information on how to assess the readiness of a Red Hat Enterprise Linux (RHEL) 7 machine, in the comfort of a web user interface, in preparation for the in-place upgrade to RHEL 8.
In the OpenShift Console version 4.3, we’ve added more capabilities around viewing and editing user management resources, including dedicated pages to view Users and Groups for the cluster. Admins can now impersonate users to see the console exactly how a user with those permissions would, making it easier to test and troubleshoot.
In response to customer feedback, we’ve introduced basic text formatting options (such as bold, italics, unordered lists/bullets, H1 and H2) when composing a comment on a support case. Plain text comments are also still supported.

Customers gave feedback about the value of an integration offering eliminating the need for installation, configuration, and operational management. In response, we created a new product offering, Red Hat Managed Integration, to make it easier than ever to access integration capabilities from Red Hat. Completely removing install and configuration time, customers can start integrating their systems with confidence faster, while Red Hat manages their platform. Additionally, solution architects can now start building proofs of concept within a day for customers.
Customer Portal OneBox Changes
The OneBox is a feature for the Customer Portal’s search application that provides additional content, information, and links based on what the customer is searching. We added new templates to reflect the unique aspects of some of our products. For example, the OneBox now has a unique template for product suites and for security vulnerabilities. These custom templates display what customers have noted as the most important information.
Resolved scaling issues with Red Hat Gluster Storage
Red Hat Gluster Storage customers pushing the limits of our supported scaling were struggling. In response, we evaluated, identified, and addressed a major bottleneck. Due to architectural limitations in the way Gluster data was distributed across data centers, customers were not able to scale out their storage in Red Hat OpenShift Container Platform. We implemented a design change that resolved the issue.
Prior to the OCS 3.9 release, customers had to look for product information in either the Red Hat Gluster Storage or Red Hat OpenShift Container Platform product pages. This scenario did not provide a dedicated, scalable source of information for the growing number of OCS customers, so we created an OCS product page to simplify and centralize the product information.
The introduction of OperatorHub.io solves a critical pain point for our user base: finding services that are operationally ready for Kubernetes - or otherwise, backed by an Operator. Just as important, OperatorHub.io is of strategic value to our product plans. OperatorHub.io listed Operators are packaged so that OpenShift deployment is a single command. The registry also establishes a pool of services to certify on OpenShift with added value such as automated updates, first line Red Hat support, and container factory scanning that will only be available on OpenShift.
Red Hat is expanding its integration product portfolio with new components and capabilities for connecting applications, data, and devices across hybrid architectures.

Introducing OpenShift Operators
OpenShift 3.11 introduced a first round of Operators, providing automated operations for complex applications deployed on OpenShift. Initial operators included MongoDB, Redis, Crunchy Data for PostgreSQL, Couchbase, etcd, and Prometheus. These operators encapsulate years of hard earned operational experience from the vendors and experts behind each. In 2019, we are going to see this paradigm expand across the Kubernetes landscape, including the use of operators to automate management of OpenShift itself.
We delivered the Helm operator kit, making it easy to wrap existing Helm charts in an operator in order to deploy and manage a Kubernetes application using the Kubernetes APIs and kubectl tooling without having to write any Go code.
OpenShift Dedicated added support for Multi-AZ stretched clusters that allow for cluster deployment across multiple availability zones (AZ). This helps to maximize service availability for product systems and applications. In addition, Dedicated added support for additional EC2 instance types including memory-optimized, compute-optimized or general purpose, which can be sized to meet specific needs. Additional enhancements include Bring Your Own AWS Account, Encrypted Storage Volumes, and Greater Admin Visibility.
Both client and server for the pNFS SCSI layout are fully supported. This requires shared storage access via a SCSI device for all client nodes that wish to use the pNFS SCSI feature. It also requires an XFS filesystem on the server side.

Specific changes have been made to the in-place upgrade tool that provides additional insight around systemd when upgrading to RHEL 7. Also, the in-place upgrade tooling has been enhanced to remove networking issues associated with the upgrade to RHEL 7 and systemd/udev so that networking keeps working after upgrade to RHEL 7.
Red Hat is pleased to announce additions and updates to our suite of developer desktop tooling products, including Container Development Kit 3.4, JBoss Developer Studio 11.3, and our DevSuite 2.3 installer. These updates are a continuation of our efforts to increase developer usability, while adding new features that matter most for users of Red Hat platforms and technologies.
The newest versions of databases in Red Hat Software Collections utilize the concept of -syspath packages, which allows users to use the RPM packages as any other package (like the files are in standard paths).
Virtual Data Optimizer (VDO) is a new Linux device mapper module that adds data reduction capabilities to Red Hat Enterprise Linux. VDO uses data deduplication and compression techniques to shrink data as it is written to storage.
Red Hat Cloudforms Improvements
Last quarter, we reported that we had added numerous performance improvements in collaboration with customers to Red Hat CloudForms 4.5 and 4.6. At that time, we were awaiting erratas and releases of those versions. Now that those two versions have been released and implemented with multiple customers, we can report that the number of customer cases related to performance has dropped precipitously.
Customers reported difficulty locating product-specific information and user documentation. As a storage integration solution (Red Hat Gluster Storage + Red Hat OpenShift Container Platform), documentation was delivered on both the RHGS and OCP pages, but no central product page was available in the Customer Portal to access information specific to Container-Native Storage releases, downloads, or support policies. Red Hat resolved this by delivering a Container-Native Storage product page with the 3.9 release with product information and dedicated documentation.
The OpenShift.io customer scenarios
The Red Hat Product Experience team regularly collaborates with QE in the OpenShift.io (OSIO) workspace, taking part in coordinated “live user” tests of our hosted product. We frequently open issue trackers throughout such exercises and these go into the current release train for the product. We also collaborate with the documentation team every release cycle (in the OSIO) to ensure documentation is useful and accurate. Our hands-on experience lets us offer insights that other stakeholders won't have.
To make renewing easier, we’ve streamlined relevant information and added functionality to Red Hat Subscription Management (RHSM) enabling a faster, more consistent renewal experience. View your subscriptions eligible for renewal and click the “Renew” link to begin the process.
Network Bound Disk Encryption
Secondary LUKS volumes can be encrypted and bound to the network service called Tang through the client side framework called Clevis. The volume is encrypted, but can be automatically decrypted only when the network service is accessible. This addresses the problem of a midnight server reboot when no one is present to type the unlocking password. If the volume leaves the environment boundary and does not have access to the network server, the volume is not decryptable unless the user types a previously defined password.
Pre-upgrade validations for undercloud (section 2.3) and overcloud (section 2.4) were added to Red Hat OpenStack Platform 12 documentation. The validations were gathered from Red Hat Support's experiences with customer updates and upgrades. These were added as basic checks to help customers ensure they are ready for an update/upgrade and serve as a “smoke test” for OSP clusters for any occasion.
Customers indicated confusion within the documentation to deploy Container-Native Storage and OpenShift Container Platform. The documentation team improved the experience by adding specific workflow content in the CNS 3.6 Deployment Guide, helping customers better understand which deployment tasks are required based on their existing environment and objectives.
Customers in larger environments were experiencing high memory usage. We saw a pattern in cases and over the course of six months, collected logs from multiple customers. We addressed immediate issues by tuning the Red Hat CloudForms Appliance together with the customer. Once we found the true source of the problem, we fixed and added performance improvements, all of which are available in upcoming errata for Red Hat CloudForms 4.5 and 4.6.
This new guide was created to meet customer requests for information about optimizing the performance of JBoss EAP deployments. The content provides optimization recommendations for common JBoss EAP use cases as well as instructions for monitoring performance and diagnosing performance issues.
