Oniux seems like an "officially" supported tool similar to orjail (which hasn't received a commit in four years, but still works great as a shell script with iptables/iproute tools [1]). Orjail has also an option to run with firejail for further isolation, which seems to be still a feature that Oniux doesn't have.
