Not really. But LXD containers are built by layering commands. I use a bash script with the commands to create reproducible containers. That said, LXD is good for containerizing OS's, not single applications. So when you say "defining reproducible environments" you can get reproducible containers, but not so much environments. In that sense, it behaves more like a VM.
