K3s Installation

Installation

All the commands in this runbook were tested against a VM with Canonical, Ubuntu, 20.04 LTS, amd64 as root.

1. Install K3s and wait for the pods to become ready:

   curl -sfL https://assets.master.k3s.getvisibility.com/k3s/k3s.sh | INSTALL_K3S_VERSION="v1.26.10+k3s1" K3S_KUBECONFIG_MODE="644" sh -s - server --node-name=local-01
   
   kubectl get deploy -n kube-system --output name | xargs -n1 -t kubectl rollout status -n kube-system

2. Install Helm 3:

   wget --quiet https://raw.githubusercontent.com/helm/helm/master/scripts/get -O /tmp/get_helm.sh \
   && chmod 0755 /tmp/get_helm.sh \
   && /tmp/get_helm.sh -v v3.8.2

3. Configure GetVisibility private Docker image registry (replace $USERNAME and $PASSWORD with the Docker credentials provided):

   kubectl create secret docker-registry gv-docker-registry \
     --docker-server=https://images.master.k3s.getvisibility.com \
     --docker-username=$USERNAME \
     --docker-password=$PASSWORD \
     --docker-email=no@email.com

4. Configure GetVisibility private Helm repository (replace $USERNAME and $PASSWORD with the Helm credentials provided):

   helm repo add gv_stable https://charts.master.k3s.getvisibility.com/stable --username $USERNAME --password $PASSWORD
   
   helm repo update

5. Install chart GetVisibility Essentials and wait for the pods to become ready.
   For Synergy (32 GB RAM machines):

   helm upgrade --install gv-essentials gv_stable/gv-essentials --wait \
   --timeout=10m0s --kubeconfig /etc/rancher/k3s/k3s.yaml \
   --set eck-operator.enabled=true --set eck-operator.settings.cpu=1 \
   --set eck-operator.settings.memory=1 --set eck-operator.settings.storage=40 \
   --set updateclusterid.enabled=false
   
   kubectl get deploy --output name | xargs -n1 -t kubectl rollout status

   For Focus and Enterprice (48+ GB RAM machines):

   helm upgrade --install gv-essentials gv_stable/gv-essentials --wait \
   --timeout=10m0s --kubeconfig /etc/rancher/k3s/k3s.yaml \
   --set eck-operator.enabled=true --set eck-operator.settings.cpu=8 \
   --set eck-operator.settings.memory=20 --set eck-operator.settings.storage=160 \
   --set updateclusterid.enabled=false
   
   kubectl get deploy --output name | xargs -n1 -t kubectl rollout status

6. Depending on the theme you want to use, run one of the commands below to install the chart GV Platform (don’t forget to replace $PRODUCT with either synergy or focus or enterprise):

   1. GetVisibility theme:

      helm upgrade --install gv-platform gv_stable/gv-platform --wait \
      --timeout=10m0s --kubeconfig /etc/rancher/k3s/k3s.yaml \
      --set-string clusterLabels.environment=prod \
      --set-string clusterLabels.cluster_reseller=getvisibility \
      --set-string clusterLabels.cluster_name=mycluster \
      --set-string clusterLabels.product=$PRODUCT

   2. Forcepoint theme:

      helm upgrade --install gv-platform gv_stable/gv-platform --wait \
      --timeout=10m0s --kubeconfig /etc/rancher/k3s/k3s.yaml \
      --set-string clusterLabels.environment=prod \
      --set-string clusterLabels.cluster_reseller=forcepoint \
      --set-string clusterLabels.cluster_name=mycluster \
      --set-string clusterLabels.product=$PRODUCT

Upgrade

GV Essentials

In order to upgrade the essential services (e.g. Postgres, Kafka, MongoDB, Consul) run helm repo update and then the same command you used in step 5.

Synergy/Focus/Enterprise

In order to upgrade Synergy/Focus/Enterprise run helm repo update and then the same command you used in step 6.

Monitoring

You can optionally also install monitoring tools to collect metrics and logs of all services that are running inside the cluster:

1. Install the CRDs:

   $ helm upgrade --install rancher-monitoring-crd gv_stable/rancher-monitoring-crd --wait \
   --kubeconfig /etc/rancher/k3s/k3s.yaml \
   --namespace=cattle-monitoring-system \
   --version=100.1.2+up19.0.5 \
   --create-namespace

2. Install the monitoring tools:

   $ helm upgrade --install rancher-monitoring gv_stable/rancher-monitoring --wait \
   --kubeconfig /etc/rancher/k3s/k3s.yaml \
   --namespace=cattle-monitoring-system \
   --version=100.1.2+up19.0.5 \
   --set k3sServer.enabled=true \
   --set k3sControllerManager.enabled=true \
   --set k3sScheduler.enabled=true \
   --set k3sProxy.enabled=true

To access the Grafana dashboard run the command kubectl port-forward svc/rancher-monitoring-grafana -n cattle-monitoring-system 3001:80 --address='0.0.0.0' and in your browser type the address http://$SERVER_IP:3001.

To access Prometheus dashboard run the command kubectl port-forward svc/rancher-monitoring-prometheus -n cattle-monitoring-system 3001:9090 --address='0.0.0.0' and in your browser type the address http://$SERVER_IP:3001.
