Kubernetes

In Kubernetes, the ThreatMapper sensors are deployed as a daemonset in the Kubernetes cluster, using a helm chart.

info

The deepfence-console helm chart by default runs agent and cluster-agent pods. The deepfence-agent helm chart need not be installed in the cluster where console helm chart is deployed.

Quick Installation of ThreatMapper Sensors

Install and start the latest release of the deepfence sensor. Replace x.x.x.x with the IP address of the Management Console and 73f6f3d0-9931-4b31-8967-fd6adf475f80 with the API key.

Identify container runtime

If container runtime is unknown, please follow these instructions.

info

clusterName is the name / identifier of the cluster. It should be different for different kubernetes clusters. Example: prod-cluster-1, test-cluster.

info

Image tag quay.io/deepfenceio/deepfence_agent_ce:2.2.0-multiarch is supported in amd64 and arm64/v8 architectures.

Deploy deepfence-agent helm chart

helm repo add deepfence https://deepfence-helm-charts.s3.amazonaws.com/threatmapper
helm repo update

# helm show readme deepfence/deepfence-agent --version 2.2.0 | less
# helm show values deepfence/deepfence-agent --version 2.2.0 | less

helm install deepfence-agent deepfence/deepfence-agent \
    --set managementConsoleUrl=x.x.x.x \
    --set deepfenceKey=73f6f3d0-9931-4b31-8967-fd6adf475f80 \
    --set global.imageTag=2.2.0 \
    --set clusterName="prod-cluster" \
    --set mountContainerRuntimeSocket.containerdSock=true \
    --set mountContainerRuntimeSocket.dockerSock=false \
    --set mountContainerRuntimeSocket.crioSock=false \
    --set mountContainerRuntimeSocket.podmanSock=false \
    --set mountContainerRuntimeSocket.containerdSockPath="/run/containerd/containerd.sock" \
    --set logLevel="info" \
    --namespace deepfence \
    --create-namespace \
    --version 2.2.0

Fine-tune the Helm deployment

helm repo add deepfence https://deepfence-helm-charts.s3.amazonaws.com/threatmapper
helm repo update

helm show values deepfence/deepfence-agent --version 2.2.0 > deepfence_agent_values.yaml

# You will need to update the following values:
#   managementConsoleUrl and deepfenceKey - specify your URL/IP and API key value
# You may wish to update other values, including:
#   image:name and image:clusterAgentImageName - change to point to custom images
#   containerdSock - set to false if agent fails to start on some Kubernetes platforms e.g. Minikube 
vim deepfence_agent_values.yaml

helm install -f deepfence_agent_values.yaml deepfence-agent deepfence/deepfence-agent \
    --namespace deepfence \
    --create-namespace \
    --version 2.2.0

Delete the ThreatMapper Sensor

helm delete deepfence-agent -n deepfence

Identify container runtime

• To get container runtime in the k8s cluster, run the following command

kubectl get nodes -o=custom-columns=NAME:.metadata.name,Runtime:.status.nodeInfo.containerRuntimeVersion

• To get container runtime socket path in the k8s cluster, run the following commands and search for --container-runtime-endpoint or containerd

kubectl apply -f https://deepfence-public.s3.amazonaws.com/kubernetes/deepfence-cluster-config-job.yaml
kubectl wait --for=condition=complete --timeout=30s job/deepfence-cluster-config
kubectl logs $(kubectl get pod -l job-name=deepfence-cluster-config -o jsonpath="{.items[0].metadata.name}")
kubectl delete -f https://deepfence-public.s3.amazonaws.com/kubernetes/deepfence-cluster-config-job.yaml
