# kuma Stack
description: Kuma Uptime Monitor for NetGrimoire
---
# kuma
## Overview
The kuma Stack is a Docker Swarm-based service stack used in NetGrimoire for monitoring and automation of Kubernetes deployments. The stack consists of two main services: kuma, which provides the primary monitoring functionality, and autokuma, which automates tasks such as configuration and deployment management.
The kuma stack is a service in NetGrimoire that monitors the status of services running on the swarm. It consists of two main components: kuma and autokuma. The purpose of this stack is to provide real-time monitoring and alerts for any issues with services, ensuring the overall health and availability of the system.

## Architecture
| Service | Image | Port | Role |
|---------|-----|-----|---------|
- **kuma:** docker4 3001 - monitoring service
- **autokuma:** docker4 3002 - automation service
Exposed via:
- kuma: http://kuma.netgrimoire.com
- autokuma: Internal only, no external access expected
Homepage group: homepage group
|---------|-----|-----|-------|
- **Host:** docker4
- **Network:** netgrimoire
- **Exposed via:** kuma:3001 (Caddy reverse proxy), internal only
- **Homepage group:** Monitoring

## Build & Configuration
### Prerequisites
No specific prerequisites for this stack.
To deploy this stack, ensure you have Docker Swarm installed and running on your manager node.
### Volume Setup
```bash
mkdir -p /DockerVol/kuma:/app/data
chown -R 1964:1964 /DockerVol/
mkdir -p /DockerVol/kuma
chown -R kuma:kuma /DockerVol/kuma
```
### Environment Variables
- `AUTOKUMA__KUMA__URL`: http://kuma:3001
- `AUTOKUMA__KUMA__USERNAME`: traveler
- `AUTOKUMA__KUMA__PASSWORD`: F@lcon12
- `AUTOKUMA__TAG_NAME`: AutoKuma
- `AUTOKUMA__DOCKER__SOURCE`: DockerSwarm
```bash
# generate: openssl rand -hex 32
AUTOKUMA__KUMA__URL: http://kuma:3001
AUTOKUMA__KUMA__USERNAME: traveler
AUTOKUMA__KUMA__PASSWORD: F@lcon12
```
### Deploy
```bash
@ -48,86 +47,69 @@ docker stack services kuma
```
### First Run
Perform the following steps after deploying the stack:
```bash
cd /DockerVol/
# Initialize the autokuma data container if it doesn't exist.
if [ ! -d "/data" ]; then
docker run --name autodocker \
--volumes /var/run/docker.sock:/var/run/docker.sock:ro \
--volumes /data:/data \
ghcr.io/bigboot/autokuma:latest
fi
./deploy.sh
```
This will initialize the autokuma service and start monitoring.

## User Guide
### Accessing kuma
| Service | URL | Purpose |
|---------|-----|---------|
- **kuma:** http://kuma.netgrimoire.com - monitoring service
- **autokuma:** Internal only, no external access expected
- **kuma**: https://kuma.netgrimoire.com (Caddy reverse proxy)
### Primary Use Cases
To get started with the monitoring service: visit `http://kuma.netgrimoire.com` in your web browser.
The primary use case for this stack is to monitor the health and availability of services in NetGrimoire. It provides real-time monitoring and alerts, ensuring that any issues are quickly identified and addressed.
### NetGrimoire Integrations
This stack integrates with NetGrimoire's homepage and provides a centralized monitoring dashboard. It also exposes information to kuma.*
This service integrates with other NetGrimoire services by exporting data to Uptime Kuma's monitoring dashboard. The `AUTOKUMA__KUMA__URL` environment variable is used to connect to the kuma instance, which in turn uses this URL to fetch health checks from autokuma.
---
## Operations
### Monitoring
Docker Stack services:
kuma monitors services running on the swarm and provides real-time alerts for any issues.
```bash
docker stack services kuma
docker service logs -f kuma
```
### Backups
Critical data is stored in `/var/run/docker.sock:/var/run/docker.sock`.
Critical backups are required to restore the system in case of a failure. The `/DockerVol/kuma` volume should be backed up regularly.
### Restore
Perform the following steps to restore from a backup:
```bash
cd /DockerVol/
# Initialize the autokuma data container if it doesn't exist.
if [ ! -d "/data" ]; then
docker run --name autodocker \
--volumes /var/run/docker.sock:/var/run/docker.sock:ro \
--volumes /data:/data \
ghcr.io/bigboot/autokuma:latest
fi
cd services/swarm/stack/kuma
./deploy.sh
```
This will redeploy the kuma stack and initialize autokuma.

## Common Failures
- **Symptom:** kuma service does not start.
- **Cause:** Autokuma service has incorrect configuration, Docker Swarm is not available on all nodes.
- **Fix:** Check the autokuma service's configuration and ensure Docker Swarm is enabled on each node.
- **Symptom:** Monitoring data is not displayed.
- **Cause:** Data sources are missing or kuma service is down.
- **Fix:** Re-run docker stack deploy command to restart services, check environment variables for data source URLs and verify that the data sources are correctly configured.
| Symptom | Cause | Fix |
|---------|------|-----|
| No monitoring data | Insufficient permissions or incorrect labels | Check labels and permissions, ensure correct configuration |
| Autokuma fails to start | Incorrect environment variables or missing required services | Review configuration, update environment variables as needed |
