Connecting to a remote dockerd on RancherOS on FreeNAS

Last summer I migrated from an old QNAP NAS to FreeNAS. I also started using docker containers with RancherOS, via the FreeNAS-provided virtual machine image. I initially installed all my containers using the RancherOS cli (ssh into the machine), but now I am moving my container configurations out of the VM cli and versioning them so that I can at any point rebuild (or upgrade) the RancherOS disk image, and be able to reload all my containers. So I want to be able to run docker commands from my localhost cli, but have them be run on the RancherOS docker daemon.
