Copy link

Red Hat Offline Knowledge Portal is a lightweight, secure, offline version of the online Red Hat Customer Portal and Knowledgebase that you can use offline and at the Edge. Wherever you need it, Red Hat Offline Knowledge Portal has the information you need to install, run, and support Red Hat products.

All features and content usable offline
Red Hat Offline Knowledge Portal runs without an internet connection, so you have a similar offline and offline experience with Red Hat knowledge content.
Open Container Initiative (OCI)-compliant image for x86_64 and aarch64
The Red Hat Offline Knowledge Portal container image runs on many device architectures and container runtimes.
Single image appliance based on ubi9/httpd-24
Red Hat Offline Knowledge Portal uses a simple platform with few moving parts, so the container image is easy to use, stable, and can run for long periods without intervention.
Knowledgebase articles and solutions
Red Hat Offline Knowledge Portal has over 140,000 articles and solutions from the Red Hat Knowledgebase that you can reference offline to troubleshoot issues in your disconnected environment.
Product documentation
Red Hat Offline Knowledge Portal has more than 8,000 product documentation titles of procedures and configuration guidance that you can reference offline to learn about and use Red Hat products.
Common Vulnerabilities and Exposures (CVE) content
Red Hat Offline Knowledge Portal has CVEs published as of the date of the container image extract, so you can identify and evaluate security vulnerabilities and assess your system- and package-level risk without internet access.
Errata content
Red Hat Offline Knowledge Portal has errata advisories for security, bug fix, and enhancement updates, so you can reference the recent and historical updates that are critical to the maintenance of your Red Hat products while offline.
Security data application programming interface (API)
Red Hat Offline Knowledge Portal includes a machine-consumable JSON format for offline CVEs and errata advisories that you can integrate into your security automation and custom tools that consume security data.
Select miscellaneous Customer Portal pages
Red Hat Offline Knowledge Portal has unique informational pages beyond Knowledgebase solutions, articles, and CVEs, so you retain access to essential support resources even when you are offline.
Search and filter content

Red Hat Offline Knowledge Portal uses a Apache Solr 9.8 server for search, so you can locate the content that is most relevant to you by using one or more of the following methods:

  • Search by keyword or phrase
  • Refine search results by product or content type
  • Filter CVEs by keyword, severity, and year
  • Filter Errata by keyword, product variants, and year
Offline link quality
Because exporting online content offline is sure to break hyperlinks, the Red Hat Offline Knowledge Portal product team applies HTTP redirects and converts absolute links to relative links for included content. Red Hat Offline Knowledge Portal denotes all links external to *.redhat.com or to content not included in Red Hat Offline Knowledge Portal with strikethrough formatting, so you can quickly identify links that do not work offline.
Customer Portal path parity
For included Customer Portal content, the online URL path is the same offline in Red Hat Offline Knowledge Portal, so you can easily share links when you coordinate with Red Hat Sales, Support, and partners.
Red Hat Offline Knowledge Portal content updated frequently
Because the content of the Red Customer Portal is constantly updated, the Red Hat Offline Knowledge Portal is usually updated weekly. However, Red Hat Offline Knowledge Portal releases rely on external factors so weekly releases are not guaranteed. In addition, releases can occur from Monday through Friday.

This section lists known issues with Red Hat Offline Knowledge Portal 1.

Issue: In Google Chrome, you are unable to load http://localhost:8080 or https://localhost:8443. This is caused by a combination of the operating system settings and Google Chrome which results in the IPv6 address ::1 being selected instead of the IPV4 address 127.0.0.1. Google Chrome attempts to resolve localhost to IPv6.

Actual result:

  • Web pages on http://localhost:8080 or https://localhost:8443 do not open in Google Chrome.

  • Google Chrome displays one of the following messages:

    • "This page isn’t working"
    • "localhost didn’t send any data"
    • "ERR_EMPTY_RESPONSE"
    • "This site can’t be reached"
    • "ERR_CONNECTION_RESET"

Expected result: Web pages open as expected on http://localhost:8080 or https://localhost:8443.

Workaround: Use http://localhost4:8080 or http://127.0.0.1:8080 to force IPv4 resolution to the local address. localhost4 and localhost6 have been available as aliases for the IPv4 and IPv6 localhost addresses respectively since Red Hat Enterprise Linux 6. Use these aliases to ensure the address of the desired protocol is resolved. However, if your systems does not have the localhost4 alias defined in the /etc/hosts file, you can use 127.0.0.1:8080.
