CPU cores: 8 (x86_64 processor with speed of 2.2 GHz or more)
RAM: 32GB
Disk: 500GB SSD
OS: we recommend Ubuntu 20.04.4 LTS Server (Focal Fossa), but you can also use RHEL 8.5, CentOS 7.9 or Suse Linux 15.3. If you are using CentOS or RHEL please refer to the official documentation for additional setup.
Firewall: the K3s server needs port 443/TCP to be open to access the application either via proxy or firewall by disabling ssl decryption and enabling auth bypass.
In order to download the application artifacts (Docker images and binaries), updates and configuration files, the cluster needs a public internet connection with download speed of 40 Mbps or more and upload speed of 8 Mbps or more. To speed up the initial setup process it is recommended to have a download speed of 100 Mbps or more.
...
The K3s deployment is complete when elements of all the deployments (coredns, local-path-provisioner, metrics-server, traefik and cattle-cluster-agent) show at least "1" as "AVAILABLE"
In case of errors you can inspect the logs of a pod using
kubectl logs, e.g.kubectl logs cattle-cluster-agent-d96d648d8-wjvl9 -n cattle-system

Once the above two commands are ran successfully then inform the Forcepoint/Getvisibility backend team to push the remaining packages from master server. |
