Uninstalling

Uninstall

On the server, run:

sudo unbind uninstall

It asks you to confirm. Then it removes the storage system and its data, removes k3s and everything running on it, and cleans up what they left on disk.

If you added more servers, remove k3s on each of them as well:

sudo /usr/local/bin/k3s-agent-uninstall.sh

Clean up the firewall rules

Leftover network rules can get in the way of whatever you install next. Flush them:

sudo iptables -F
sudo iptables -t nat -F
sudo iptables -t mangle -F
sudo iptables -X

Or reboot the server, which has the same effect.

What is not removed

• Packages the installer added, like git, curl and the iSCSI tools.
• The swap file, if the installer created one: /swapfile and its line in /etc/fstab.
• DNS records at your DNS provider.
• The GitHub App Unbind created in your GitHub account. Delete it under GitHub > Settings > Developer settings > GitHub Apps.
• Backups in your S3 buckets.

The cleanest way to leave is still to delete the server.
