I’ll commit today or in the coming days. Ofc it requires docker to be installed so I’ll create a “docker” profile in the build so that the build doesn’t break on agents which don’t have docker installed yet. It’ll allow you to start testing it on your local machines. >>> >>> * I have updated the design page at http://design.xwiki.org/xwiki/bin/view/Proposal/ConfigurationTesting >>> >>> Next steps: >>> >>> * Commit the work one (in the coming days) >>> * I have started trying to deploy XWiki in an embedded undertow. Still not working at this stage (but I’ve progressed). I still don’t know if this is going to work or not.
