You can install Synergy and Focus DSPM in an air-gapped environment that is not directly connected to the Internet.

...

Note
Make sure you have `/usr/local/bin` configured in your PATH: `export PATH=$PATH:/usr/local/bin`). All the commands must be executed as `root` user.

Info
The commands have been tested on Ubuntu Server 20.04 LTS, SUSE Linux Enterprise Server 15 SP4 and RHEL 8.10.

Note

For RHEL, K3s needs the following package to be installed: k3s-selinux (repo rancher-k3s-common-stable) and its dependencies container-selinux (repo rhel-8-appstream-rhui-rpms) and policycoreutils-python-utils (repo rhel-8-baseos-rhui-rpms). On systems without access to online repositories, the corresponding *.rpm package for each of the above dependencies should be copied to the server first and installed locally.Also, firewalld nm-cloud-setup.service and nm-cloud-setup.timer must be disabled and the server restarted before the installation.

Ubuntu prerequisites: Prerequisites for k3s on Ubuntu Linux

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

Extract the downloaded file:

Code Block
tar -xf gv-platform-$VERSION.tar # (replace$VERSION according to downloaded file)

Prepare K3s for air-gap installation:

Code Block

breakoutMode	wide
language	bash

...

sudo su -
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

Before installation, it’s recommended to run automatic checks (as root; PRODUCT_NAME is either

...

“synergy” (endpoint agent) or “dspm“ (dspm without endpoint agent) or “ultimate“ (dspm + endpoint agent). If unsure use “ultimate“):
Code Block

...

cat scripts/k3s.sh | PRODUCT_NAME=

...

ultimate 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

Info

Few more arguments that can be used to customize the execution of the k3s script:
SKIP_PRECHECK=true to skip the execution of the precheck script while installing k3s service

SKIP_SYSTEM_CHECKS=true to skip the system hardware checking during precheck

SKIP_NETWORK_CHECKS=true to skip the system network connectivity checking during precheck

Example:

cat scripts/k3s.sh | INSTALL_K3S_SKIP_DOWNLOAD=true SKIP_PRECHECK=true K3S_KUBECONFIG_MODE="644" sh -s - server --node-name=local-01

...

Import Docker images locally:

Code Block

breakoutMode	wide
language	bash

...

mkdir /tmp/import

...


for f in images/*.gz; do IMG=$(basename "${f}" .gz); gunzip -c "${f}" > /tmp/import/"${IMG}"; done

...


for f in /tmp/import/*.tar; do ctr -n=k8s.io images import "${f}"; done

Install Helm charts

The following steps guide you through the installation of the dependencies required by Focus DSPM and Synergy (Endpoint Agent).

Info

Replace $VERSION with the version that is present in the bundle that has been downloaded.
To check all the charts that have been download downloaded run ls charts.

Replace IPADDRESS/DNS/FQDN with IP Adress or FQDN or DNS name for Keycloak in formats like below
https://192.168.10.1 or https://gv.domain.local or https://gv.getvisibility.com .local or https://gv.getvisibility.com
In case you want to enable kibana on airgap cluster add below setting to the Helm command
--set eck-operator.kibanaEnabled=true

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.enabled=true \
--set updateclusterid.enabled=false \
--set keycloak.url=https://(IPADDRESS/|DNS/|FQDN)

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

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 \

Info
To expose Grafana via an ingress on the path `/grafana` (allowing access through `https://IPADDRESS_or_DNSNAME/grafana`), add the following flag to the monitoring installation command:

...

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

Install

...

DSPM/Synergy (Endpoint Agent) Helm Chart

Replace the following variables:

$VERSION with the version that is present in the bundle that has been downloaded
$RESELLER with the reseller code (either getvisibility or forcepoint)
$PRODUCT with the product being installed (synergy, dspm, enterprise or ultimate)

Code Block

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

Info

In case if you expirience experience 404 error for accessing to Keycloak or UI and use 1.26 (default) version of K3s ensure that treafik traefik patch is applied

Code Block

# kubectl patch clusterrole traefik-kube-system -n kube-system --type='json' -p='[{"op": "add", "path": "/rules/-1/apiGroups/-", "value": "traefik.io"}]'
# kubectl apply -f assets/traefik-patch.yaml
#
kubectl rollout restart deployment traefik -n kube-system

...

The following port must be publicly exposed in order to allow users to access Synergy (Endpoint Agent) or Focus DSPM product:

Protocol	Port	Description
TCP	443	FocusDSPM/Synergy (Endpoint Agent) backend

The user must not access the K3s nodes directly, instead, there should be a load balancer sitting between the end user and all the K3s nodes (master and worker nodes):

...

The following steps guide you through the installation of the dependencies required by Focus DSPM and Synergy (Endpoint Agent).

Note
Perform the following steps in the master1 Node

...

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 \

DSPM/Synergy (Endpoint Agent) Helm Chart

Replace the following variables:

$VERSION with the version that is present in the bundle that has been downloaded
$RESELLER with the reseller code (either getvisibility or forcepoint)
$PRODUCT with the product being installed (synergy or focus dspm or enterprise ultimate)

Code Block

--set-string clusterLabels.cluster_reseller=$RESELLER \
--set-string clusterLabels.cluster_name=mycluster \
--set-string clusterLabels.product=$PRODUCT

...

Before upgrading each chart, you can check the settings used in the current installation with
helm get values <chartname>.
If the current values are different from the defaults, you will need to change the parameters of the
helm upgrade command for the chart in question.
For example, if the backup is currently set to run at 2 AM instead of the 1 AM default, change
--set backup.hour=1 to --set backup.hour=2.
Below is a mostly default config.
