The steps below you guide you through the air-gap installation of K3s, a lightweight Kubernetes distribution created by Rancher Labs:

1. Extract the downloaded file: tar -xf gv-platform-$VERSION.tar

2. Prepare K3s for air-gap installation:

   Code Block
   language bash
   # mkdir -p /var/lib/rancher/k3s/agent/images/ # gunzip -c assets/k3s-airgap-images-amd64.tar.gz > /var/lib/rancher/k3s/agent/images/airgap-images.tar # cp assets/k3s /usr/local/bin && chmod +x /usr/local/bin/k3s # tar -xzf assets/helm-v3.8.2-linux-amd64.tar.gz # cp linux-amd64/helm /usr/local/bin

3. Install K3sBefore installation, it’s recommended to run automatic checks (as root; PRODUCT_NAME is either “enterprise” or “synergy” or “focus“):

   bash

   Code Block
   language
   # cat scripts/k3s.sh | INSTALL_K3S_PRODUCT_NAME=enterprise ONLY_PRECHECK=true bash -

   
   Install K3s:

   Code Block
   language bash
   # cat scripts/k3s.sh | INSTALL_K3S_SKIP_DOWNLOAD=true K3S_KUBECONFIG_MODE="644" SKIP_NETWORK_CHECKS=true sh -s - server --node-name=local-01

...

...

...

...

...

...

...

4. Wait for the 30s and check if K3s is running with the command: kubectl get pods -A and systemctl status k3s.service

Import Docker images

The steps below will manually deploy the necessary images to the cluster.

...

1. Install Getvisibility Essentials and set the daily UTC backup hour (0-23) for performing backups.

   Code Block
   # helm upgrade --install gv-essentials charts/gv-essentials-$VERSION.tgz --wait \ --timeout=10m0s --kubeconfig /etc/rancher/k3s/k3s.yaml \ --set backup.hour=1 \ --set eck-operator-operator.enabled=true \ --set updateclusterid.enabled=truefalse \ --set updateclusteridkeycloak.enabled=falseurl= IPADDRESS/DNS/FQDN

2. Install Monitoring CRD:

   Code Block
   # helm upgrade --install rancher-monitoring-crd charts/rancher-monitoring-crd-$VERSION.tgz --wait \ --kubeconfig /etc/rancher/k3s/k3s.yaml \ --namespace=cattle-monitoring-system \ --create-namespace

3. Install Monitoring:

   Code Block
   # helm upgrade --install rancher-monitoring charts/rancher-monitoring-$VERSION.tgz --wait \ --kubeconfig /etc/rancher/k3s/k3s.yaml \ --namespace=cattle-monitoring-system \ --set k3sServer.enabled=true \ --set k3sControllerManager.enabled=true \ --set k3sScheduler.enabled=true \ --set k3sProxy.enabled=true \ --set prometheus.retention=5--set prometheus.retention=5

--set global.grafana_ingress.enabled=true

4. Check all pods are Running with the command: kubectl get pods -A

Install Focus/Synergy Helm Chart

...

1. Install Getvisibility Essentials and set the daily UTC backup hour (0-23) for performing backups.
   If you are installing Focus or Enterprise append --set eck-operator.enabled=true to the command in order to enable ElasticSearch.

   Code Block
   $ helm upgrade --install gv-essentials charts/gv-essentials-$VERSION.tgz --wait \ --timeout=10m0s --kubeconfig /etc/rancher/k3s/k3s.yaml \ --set global.high_available=true \ --set eck-operator.enabled=true \ --set minio.replicas=4 \ --set minio.mode=distributed \ --set consul.server.replicas=3 \ --set updateclusterid.enabled=false \ --set backup.hour=1

2. Install Monitoring CRD:

   Code Block
   $ helm upgrade --install rancher-monitoring-crd charts/rancher-monitoring-crd-$VERSION.tgz --wait \ --kubeconfig /etc/rancher/k3s/k3s.yaml \ --namespace=cattle-monitoring-system \ --create-namespace

3. Install Monitoring:

   Code Block
   $ helm upgrade --install rancher-monitoring charts/rancher-monitoring-$VERSION.tgz --wait \ --kubeconfig /etc/rancher/k3s/k3s.yaml \ --set global.high_available=true \ --namespace=cattle-monitoring-system \ --set loki-stack.loki.replicas=2 \ --set prometheus.prometheusSpec.replicas=2

--set global.grafana_ingress.enabled=true

4. Check all pods are Running with the command:
   kubectl get pods -A
