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
