No, the Docker container comes with only the software, I’d suggest you to use the `humann:3.0.0.a.4.plus.utility.dbs` image which also includes the mapping utilities.

You can specify the path in which the HUMAnN databases will be installed with the last `humann_databases` parameter, but what I would do is to have both the UniRef and CHOCOPhlAn databases in a local directory and mount it via volume binding and run HUMAnN with the `--nucleotide-database` and `--protein-database` parameters in order to point to the correct database location
