Docker docs:
Docker routes container traffic in the nat table, which means that packets are diverted before it reaches the INPUT and OUTPUT chains that ufw uses. Packets are routed before the firewall rules can be applied, effectively ignoring your firewall configuration.
It’s been about a day since this issue and now I’ve been keeping a close eye on my local-lvm, it fills fast, like, ridiculously fast and I’ve been having to run
sudo fstrim /inside the VM just to keep it maintained. I’m finding it weird I’m now just noticing this as this server has been running for months!For now I edited my
/etc/bash.bashrcso whenever I ssh in it’ll automatically runsudo fstrim /, there is something I’m likely missing but this works as a temporary solution.
