🦩 FleetDM Stack

Helm chart deploying FleetDM Server with MySQL and Redis to Kubernetes. Suitable for local development (Kind/Minikube) and adaptable for production.

Prerequisites

• Docker
• kubectl
• Helm 3
• Kind or Minikube for local cluster

Quick Start

# Create local cluster and deploy
make cluster
make install

# Verify deployment
make verify

# Access Fleet UI at https://localhost:8585
make port-forward

Installation

1. Create local cluster

Creates a Kind or Minikube cluster and installs the nginx ingress controller (Kind) or enables ingress addon (Minikube).

# Default: Kind
make cluster

# Or use Minikube
make cluster CLUSTER_TYPE=minikube

2. Install the Helm chart

make install

This will:

• Update Helm dependencies
• Create the fleetdm namespace
• Deploy MySQL, Redis, and FleetDM Server
• Run fleet prepare db automatically on fresh install (via autoApplySQLMigrations)

3. Access Fleet UI

# Port-forward Fleet to https://localhost:8585
make port-forward

# Or use a custom port
make port-forward FLEET_PORT=9090

Open https://localhost:8585 in your browser (accept the self-signed certificate).
Fleet setup wizard will guide you through initial configuration.

Teardown

# Remove Helm release and namespace
make uninstall

# Remove cluster (Kind or Minikube)
make clean

Verification

make verify

Verification checklist:

Component	Check
FleetDM	Pods running; make port-forward → https://localhost:8585
MySQL	fleetdm-stack-mysql service; Fleet connects and runs migrations
Redis	fleetdm-stack-redis-master service; Fleet uses it for cache

Manual verification

# Check pods
kubectl get pods -n fleetdm

# Check Fleet migration job (fleet prepare db)
kubectl get jobs -n fleetdm

# Check services
kubectl get svc -n fleetdm

# Fleet logs
kubectl logs -n fleetdm -l app=fleet -f

Configuration

Value	Description	Default
mysql.auth.password	MySQL password	fleetdm-local-dev
fleet.replicas	Fleet server replicas	1
fleet.hostName	Ingress host	fleet.localhost

Override via --set or custom values file:

helm upgrade --install fleetdm-stack fleetdm-stack/ \
  -n fleetdm \
  --set mysql.auth.password=SECURE_PASSWORD

TLS certificates

For local development, the chart includes self-signed TLS certificates (generated on first make install). Production deployments should use cert-manager or provide proper certificates via fleet.secretName.

FleetDM agent reachability

Fleet is exposed via port-forward (make port-forward) or ingress:

• Fleet UI — https://localhost:8585 (via port-forward)
• Agent endpoints (/api/v1/osquery/*, /api/fleet/orbit/*) — same URL
• Ingress with fleet.localhost is also configured as a fallback

For production, configure proper TLS and a stable DNS name for agents.

Enhancements implemented

1. Basic CI pipeline — Gitea Actions lint on push, release on tag (see .github/workflows/release.yaml)
2. Exposed Fleet UI — make port-forward on port 8585 (+ ingress fleet.localhost)
3. fleet prepare db — Handled by autoApplySQLMigrations: true in the Fleet Helm chart
