Anonymization filters only apply to text files. It cannot handle non-Jenkins URLs, custom proprietary Jenkins plugin names, and exceptions quoting invalid Groovy code in a Jenkins pipeline. The active plugins, disabled plugins, failed plugins, and
Dockerfile reports are not anonymized due to several Jenkins plugins and other Java libraries using version numbers that are indistinguishable from IP addresses. These reports are in the files
docker/Dockerfile. These files should all be manually reviewed if you do not wish to disclose the names of custom proprietary plugins.
