We have a cluster with a single node, and it was set up using the docker command
sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher
The server has 4Tb but now, with more than 512Gb available the node has disk pressure, and all our apps have stopped. I’ve read about setting the --low-diskspace-threshold-mb in kubelet, but I don’t know how to do that.
@Alex_Griffiths no, I didn’t. After several problems with rancher and kubernetes I decided to stop using it in our architecture. We had very serious issues and our production environment got down all of the sudden several times, and sometimes for hours. Way too many issues, not worth it.
