Description
Description
Install of a kURL cluster does not set IPv6 forwarding.
Reproduction Steps
On an IPv6 node run curl https://kurl.sh/f7deea4 | sudo bash
Expected Behavior
IPv6 forwarding on IPv6 node(s) should be set to 1 during install.
Additional Information
Setting can be set in the kubernetes_sysctl_config function inside kURL script
if ! cat /etc/sysctl.conf | grep "^net.ipv6.conf.all.forwarding" | tail -n1 | grep -Eq "^net.ipv6.conf.all.forwarding\s*=\s*1"; then
echo "net.ipv6.conf.all.forwarding = 1" >> /etc/sysctl.conf
fi
