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.
This post inspired me to try podman, after it pulled all the images it needed my Proxmox VM died, VM won’t boot cause disk is now full. It’s currently 10pm, tonight’s going to suck.
eh, booting into single user mod should work fine, uninstall podman and init 5
Okay so I’ve done some digging and got my VM to boot up! This is not Podman’s fault, I got lazy setting up Proxmox and never really learned LVM volume storage, while internally on the VM it shows 90Gb used of 325Gb Proxmox is claiming 377Gb is used on the LVM-Thin partition.
I’m backing up my files as we speak, thinking of purging it all and starting over.
Edit: before I do the sacrificial purge This seems promising.
Don’t do that. You’ll learn nothing.
So I happened to follow the advice from that Proxmox post, enabled the “Discard” option for the disk and ran
sudo fstrim /within the VM, now the Proxmox LVM-Thin partition is sitting at a comfortable 135Gb out of 377Gb.Think I’m going to use this
fstrimcommand on my main desktop to free up space.I think linux does fstrim oob.
edit: I meant to say linux distros are set up to do that automatically.
