Jails have been around a long time in comparison

I still see FreeBSD as being great for things like networking devices and storage controllers. You can apply a lot of the "cattle vs pets" design one level above that using VMs and orchestration tools.

> lauding their simplicity and ease of use

Spawning a linux container is much simpler and faster than spawning a freebsd jail.

I don’t know why i keep hearing about jails being better, they clearly aren’t.

If you don't want to use the base system (which docker is NOT the base system on Linux) then Bastille offers a pretty much identical workflow to docker, but built on FreeBSD jails: https://github.com/BastilleBSD/bastille

> I don’t know why i keep hearing about jails being better

Jails have a significantly better track record in terms of security.

I can delegate a ZFS dataset to a jail to let the jail manage it.

Do Linux containers have an equivalent to VNET jails yet? With VNET jails I can give the jail its own whole networking stack, so they can run their own firewall and dhcp their own address and everything.

You've been able to setup separate firewalls, network interfaces, IP addresses, etc. for probably 20 years using network namespaces. How do you think container networking is implemented? But you can also use it through other tools; for example, I use firejail to isolate a couple of proprietary desktop applications such that they cannot contact anything on my desktop (or network in general) except the internet gateway.

Is there a docker-compose analogue in Bastille? I like being able to spin up an isolated local copy of my infrastructure, run integration tests, and then tear it all down automatically. I'd like to be able to do a similar thing with jails. I wonder if there's a straightforward way to achieve something similar with VNET jails?

Not that I'm aware of. FreeBSD did recently gain support for OCI containers and therefore has podman. I see podman-compose is in the ports tree, but I haven't tried it myself.

Sorry what? It's a 5 line configuration file to create a FreeBSD jail.
