Quickstart

This section helps you to quickly install Edge on a Lightweight Kubernetes (K3s) cluster with default options. For detailed instructions, see Installing Edge on Kubernetes.

1. Verify that your hardware meets the requirements specified in Prerequisites.

2. Run the command below to install K3s.

   USER_NAME=$(whoami)
   USER_HOME=$(eval echo ~${USER_NAME})
   sudo sh -c '
      touch /etc/sysctl.d/90-kubelet.conf  && \
      sed -i "/^vm\.panic_on_oom=/d; /^vm\.overcommit_memory=/d; /^kernel\.panic=/d; /^kernel\.panic_on_oops=/d" /etc/sysctl.d/90-kubelet.conf && \
      printf "vm.panic_on_oom=0\nvm.overcommit_memory=1\nkernel.panic=10\nkernel.panic_on_oops=1\n" | tee -a /etc/sysctl.d/90-kubelet.conf && \
   
      sysctl -p /etc/sysctl.d/90-kubelet.conf && \
   
      curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.25.13+k3s1 sh -s - \
         --write-kubeconfig-mode 644 \
         --disable=traefik \
         --protect-kernel-defaults true \
         --kube-apiserver-arg=admission-control=ValidatingAdmissionWebhook,MutatingAdmissionWebhook && \
   
      mkdir -p '"$USER_HOME"'/.kube && \
      cp /etc/rancher/k3s/k3s.yaml '"$USER_HOME"'/.kube/config && \
      chown '"$USER_NAME:"' '"$USER_HOME"'/.kube/config && \
      chmod 600 '"$USER_HOME"'/.kube/config && \
   
      printf "\e[32mSuccessfully installed k3s!\e[0m\n" && \
   
      k3s crictl pull rancher/klipper-lb:v0.4.4 && \
      k3s crictl pull rancher/mirrored-metrics-server:v0.6.3 && \
      k3s crictl pull rancher/local-path-provisioner:v0.0.24
   '
   

3. Run the command below to install Helm v3.

   curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash
   

4. Run the command below to install the Edge operator and provide the registry credentials when prompted.

   curl -sfL https://cumulocity.com/docs/files/edge-k8s/c8yedge-operator-install.sh -O && bash ./c8yedge-operator-install.sh
   

5. Run the command below to apply Edge CR (c8yedge-sample.yaml) for installing Edge version 1018.0.1 named c8yedge with the domain myown.iot.com.

   kubectl apply -f https://cumulocity.com/docs/files/edge-k8s/c8yedge-sample.yaml
