As an alternative to local files service discovery Prometheus also support discoveries form HTTP endpoints. In a Kubernetes setup, with the Prometheus operator, it makes more sense to use this [HTTP SD](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#http_sd_config) instead of mounting the output file of the `prometheus-pve-sd` to the container.
|
||
|
|
|
||
|
|
The `prometheus-pve-sd` module doesn't have a dedicated HTTP endpoint, therefore you need to use a web server sidecar, that hosts the static file. The following deployment configuration can serve as a starting point for most setups, and just requires some minor adjustments, depending on your Kubernetes setup.
|
||
|
|
|
||
|
|
## Kubernetes configuration
|
||
|
|
|
||
|
|
Deployment configuration:
|
||
|
|
|
||
|
|
```YAML
|
||
|
|
apiVersion: apps/v1
|
||
|
|
kind: Deployment
|
||
|
|
metadata:
|
||
|
|
creationTimestamp: null
|
||
|
|
labels:
|
||
|
|
app: proxmox-service-discovery
|
||
|
|
name: proxmox-service-discovery
|
||
|
|
spec:
|
||
|
|
replicas: 1
|
||
|
|
selector:
|
||
|
|
matchLabels:
|
||
|
|
app: proxmox-service-discovery
|
||
|
|
strategy: {}
|
||
|
|
template:
|
||
|
|
metadata:
|
||
|
|
creationTimestamp: null
|
||
|
|
labels:
|
||
|
|
app: proxmox-service-discovery
|
||
|
|
spec:
|
||
|
|
containers:
|
||
|
|
- image: nginx
|
||
|
|
name: webserver
|
||
|
|
resources: {}
|
||
|
|
ports:
|
||
|
|
- containerPort: 80
|
||
|
|
protocol: TCP
|
||
|
|
name: http
|
||
|
|
volumeMounts:
|
||
|
|
- name: pve-sd-output
|
||
|
|
mountPath: /usr/share/nginx/html
|
||
|
|
- image: thegeeklab/prometheus-pve-sd
|
||
|
|
name: prometheus-pve-sd
|
||
|
|
resources: {}
|
||
|
|
env:
|
||
|
|
- name: PROMETHEUS_PVE_SD_OUTPUT_FILE
|
||
|
|
value: /tmp/pve/proxmox.json
|
||
|
|
# Add more configurations here, or use a configMap or secret to inject the remaining configs
|
||
|
|
volumeMounts:
|
||
|
|
- name: pve-sd-output
|
||
|
|
mountPath: /tmp/pve/
|
||
|
|
volumes:
|
||
|
|
- name: pve-sd-output
|
||
|
|
emptyDir: {}
|
||
|
|
status: {}
|
||
|
|
```
|
||
|
|
|
||
|
|
Additionally you will need a service, that exposes the HTTP endpoint within Kubernetes so Prometheus can scrape it.
|
||
|
|
|
||
|
|
Service configuration:
|
||
|
|
|
||
|
|
```YAML
|
||
|
|
apiVersion: v1
|
||
|
|
kind: Service
|
||
|
|
metadata:
|
||
|
|
name: pve-sd-service
|
||
|
|
spec:
|
||
|
|
selector:
|
||
|
|
app: proxmox-service-discovery
|
||
|
|
ports:
|
||
|
|
- protocol: TCP
|
||
|
|
port: 80
|
||
|
|
targetPort: 80
|
||
|
|
```
|
||
|
|
|
||
|
|
After configuring and starting the service, Prometheus need to be [configured](/usage/getting-started/#prometheus-configuration) to use the external service discovery.
