Docker Installation

Deploy Telegen using Docker or Docker Compose.

Prerequisites

• Docker 20.10+
• Linux host with kernel 4.18+ (for eBPF)
• Root/sudo access

---

Quick Start

Single Container (Agent Mode)

docker run -d --name telegen \
  --privileged \
  --pid=host \
  --network=host \
  -v /sys:/sys:ro \
  -v /proc:/host/proc:ro \
  -v /sys/kernel/debug:/sys/kernel/debug \
  -v /sys/fs/bpf:/sys/fs/bpf \
  -e TELEGEN_OTLP_ENDPOINT=otel-collector:4317 \
  ghcr.io/mirastacklabs-ai/telegen:latest

With Configuration File

# Create config directory
mkdir -p /etc/telegen

# Create configuration
cat > /etc/telegen/config.yaml <<EOF

Docker Compose

Agent Mode

Create docker-compose.yaml:

version: '3.8'

services:

    image: ghcr.io/mirastacklabs-ai/telegen:latest
    container_name: telegen
    restart: unless-stopped
    privileged: true

      interval: 30s
      timeout: 10s
      retries: 3

    container_name: telegen-collector
    restart: unless-stopped
    
    ports:
      - "162:162/udp"   # SNMP traps

Troubleshooting

Container Won’t Start

# Check logs
docker logs telegen

# Verify privileged mode
docker inspect telegen | grep -i privileged

eBPF Errors

# Check kernel version
uname -r

# Check BPF filesystem
mount | grep bpf

# Check BTF availability
ls /sys/kernel/btf/vmlinux

No Telemetry

# Test OTLP connectivity
docker exec telegen wget -q -O- http://otel-collector:4317/health

# Check agent health
docker exec telegen wget -q -O- http://localhost:8080/healthz
