Inspektor Gadget (eBPF Data Collection)

Flowfish uses Inspektor Gadget to collect eBPF-based network, DNS, process, and security events. Without it, analyses will complete but all event counts will remain at 0 — this includes the Dashboard (connections, traffic, DNS), Dependency Map, and Network Explorer.

Docker Compose users: Inspektor Gadget is a Kubernetes-native DaemonSet and cannot run in Docker Compose. It requires the Kubernetes API for pod/container discovery and metadata enrichment. If you deployed Flowfish via Docker Compose, add a remote Kubernetes cluster via Token method in the UI (Clusters > Add Cluster > Token) to collect eBPF events.

Option A: Deploy Gadget Locally (amd64 Linux only)

If your cluster runs on amd64 (x86_64) Linux with kernel 5.4+, you can deploy Inspektor Gadget directly alongside Flowfish:

# If you used the deploy.sh script:
curl -sL https://raw.githubusercontent.com/taylanbakircioglu/flowfish/main/local-test/deploy.sh | bash -s install-with-gadget

# Or apply the manifest manually:
kubectl apply -f https://raw.githubusercontent.com/taylanbakircioglu/flowfish/main/local-test/15-inspektor-gadget.yaml

# Verify the DaemonSet is running:
kubectl get pods -l app=inspektor-gadget -n flowfish-local

After Gadget pods are Running, add your cluster as In-Cluster:

1. Go to Clusters > Add Cluster
2. Select In-Cluster connection type
3. Enter a name and click Save

You can now start analyses and see real eBPF network data.

Important: ARM64 (Apple Silicon / M-series Mac) is not supported by Inspektor Gadget. If you are on ARM64, use Option B below.

Option B: Add a Remote Cluster (any platform)

If your local machine is ARM64, or you want to analyze a different cluster:

1. Deploy Flowfish locally (standard install, without Gadget)
2. On the target cluster (the one you want to analyze), run the setup script generated by Flowfish, or manually create a ServiceAccount:

kubectl create serviceaccount flowfish-reader -n default
kubectl create clusterrolebinding flowfish-reader-binding \
  --clusterrole=cluster-admin \
  --serviceaccount=default:flowfish-reader
TOKEN=$(kubectl create token flowfish-reader -n default --duration=8760h)
API_SERVER=$(kubectl config view --minify -o jsonpath='{.clusters[0].cluster.server}')
echo "API Server: $API_SERVER"
echo "Token: $TOKEN"

3. In Flowfish UI: Clusters > Add Cluster > Connection type: Token
4. Paste the API Server URL and Token from the output above
5. Inspektor Gadget must be installed on the target cluster for eBPF events

Alternatively, in the Flowfish UI cluster add screen, click "Get Setup Scripts" to download an auto-generated script for your provider. This script automatically installs Inspektor Gadget, creates the ServiceAccount/RBAC, and outputs the required values (API Server URL, Token, CA Certificate, Gadget Namespace) to paste into the form.

Option C: Full Production Install on Target Cluster

For comprehensive monitoring, deploy Flowfish directly on the cluster you want to analyze using the production manifests (deployment/kubernetes-manifests/). This includes Inspektor Gadget DaemonSet, and you can use In-Cluster connection type.

Troubleshooting

# Check pod events
kubectl describe pod <pod-name> -n flowfish-local

# Database connectivity
kubectl exec -n flowfish-local deploy/postgresql -- pg_isready -U flowfish

# NodePort conflict (change 30080 in 14-nginx-proxy.yaml if needed)
kubectl get svc --all-namespaces | grep 30080
