XWiki (Helm)
About
XWiki is a free wiki software platform written in Java with a design emphasis on extensibility. As an application wiki, XWiki allows for the storing of structured data and the execution of server side script within the wiki interface. Scripting languages including Velocity, Apache Groovy, Python, Ruby and PHP can be written directly into wiki pages using wiki macros. XWiki code is licensed under the GNU Lesser General Public License and hosted on GitHub where everyone is free to fork the source code and develop changes in their own repository. While most of the active developers are funded by commercial support company XWiki SAS, XWiki SAS maintains a strict boundary between itself and the XWiki free software project. [source]
Background
Behemoth LTD was in a search for a 'knowledge base' software, a central place to collect and collaborate on documents which hold information, instructions, guide, etc. The requirement was simple, it required to be able to run on Kubernetes without too much customization, building, testing and other complex CI/CD prerequisite.
Things may change in the future, as Kubernetes become the de-facto way to run Apps, so do some homework before continuing, Awesome Selfhosted.
