I’m very much biased towards Podman, but from what I understand rootless Docker is a bit of an afterthought, while Podman has been developed from the ground up with rootless in mind. That should be reason enough.

The very few things Docker can do that Podman struggles a bit with are stuff that usually involves mounting the Docker socket in the container or other stupid things. Since you care about security, you wouldn’t do that anyway. Not to mention there’s also rootful Podman, when you need that level of access.

I’d recommend an RPM-based distro with Podman, the few times I’ve tried Podman on a deb distro, there’s always been something wonky. It’s been a while, though.

The official app doesn’t need to be running constantly. It only needs to connect to Meta’s servers once every 14 days.

The Mautrix-Whatsapp bridge will send a notification couple of days in advance to warn you if the main device hasn’t been active.

It might work, I haven’t tried. But I think that’s also quite complicated for most people.

I’ve also heard quite a few people getting their number banned by only running in an emulator. If it’s an older WA account, it’s probably safe, but I wouldn’t do it on a fresh number.

This is true.

I use WA via the Matrix bridge. WA requires the official mobile app (not web) to connect every 14 days, so you need to have it on a separate profile, a spare phone or do a complicated Android emulator setup… To be usable you need to allow the WA app access to your contacts, which results in Meta getting just about the same metadata from you it would via using the official app.

If I wasn’t using Matrix for other things like notifications from servers, I wouldn’t bother with this. The only upside is having only one app for messaging. The bridge system itself works really well, nothing bad to say there.

Maybe you get the possibility of routing all traffic from a container (or all the containers in that namespace/network) over the tailnet this way? With the host method, you’d need the host to use the exit node too.

Have you considered lowering the unprivileged port limit instead?

sudo sysctl -w net.ipv4.ip_unprivileged_port_start=53 | sudo tee -a /etc/sysctl.conf  

Then remove the firewall rule and bind to port 53.
