OVOS Docker is one of the fastest ways to get started with OVOS. However it is a newer development and some things are not working 100% (as of August 2023, this is the GUI). That said, if you don't need full GUI support using ovos-docker will get you a working OVOS system in minutes.
Note: It works fine with rootless podman, despite being named ovos-docker.
Refer to the ovos-docker/README for information on how to use it.
