There are at least three unofficial container distributions of IkiWiki:
dgsb/ikiwiki (source on GitHub), based on Debian Stretch, lighttpd and an internal ssh server
ankitrgadiya/ikiwiki (source on GitHub), based on Debian stable and nginx, by ankit, last updated 2018
opinionated-ikiwiki (source on GitHub), based on Debian 13, and Apache httpd, by Jon
These can be used with a container runtime such as Docker or Podman.
