Port Range Configuration

The following methods are common practices and may vary depending on the system environment. If they do not work as expected, please refer to relevant documentation and troubleshooting solutions.

Docker Deployment

sudo nano /etc/sysctl.conf
Add the following content to specify ip_local_port_range:

net.ipv4.ip_local_port_range = 20000 50000

Run sudo sysctl -p to apply the changes
Restart Docker service

K3s Deployment

sudo nano /etc/systemd/system/k3s.service
Edit the ExecStart in the following settings to specify service-node-port-range

ExecStart=/usr/local/bin/k3s \
    server \
    --kube-apiserver-arg service-node-port-range=20000-50000

sudo systemctl daemon-reload
sudo systemctl restart k3s
