Slow Broadband Customers

Some customers who experience very slow broadband may require some adjustments in the way they retrieve images. This entails adding two additional settings to their K3S installation. These settings will reduce the frequency of image redownloads from every 2 minutes to every 30 minutes and will also restrict parallel image downloads. These changes will benefit customers with slow broadband connections.

To apply these changes, you need to open the file with sudo permissions and add the following lines exactly as shown in the example:

sudo vim /etc/system/systemd/k3s.service

Add the lines inside the file [check example below at end of the document]:

ExecStart=/usr/local/bin/k3s \
  server \
  --kubelet-arg=runtime-request-timeout=30m0s \
  --kubelet-arg=serialize-image-pulls=true

Save the file and then execute the following commands:

systemctl daemon-reload
systemctl restart k3s.service
systemctl status k3s.service
