using Nexus2 we have stored the nexus.xml with all the configuration settings in our git repo so we can always recreate our nexus from scratch. With nexus3 the structures seems changed and I can't find if there is a similar xml file that holds the repositories and other configuration settings so I could add this file to our git repo. When I have such a file I could create a docker image that contains this config so no configuration time is necessary in the future.
