A quite new project called runj has been created which offers an interface between FreeBSD Jails and containerd. runj is already in the Ports tree or it can be found at https://github.com/samuelkarp/runj. The Potluck container image library wants to provide complex services out of the box, like e.g. a complete postfix secondary mailserver. Many of the images are prepared to be orchestrated via nomad and nomad-pot-driver (which also is in the Ports tree).
