## Compose sample
|
|
### Prometheus & Grafana
|
|
|
|
Project structure:
|
|
```
|
|
.
|
|
├── compose.yaml
|
|
├── grafana
|
|
│ └── datasource.yml
|
|
├── prometheus
|
|
│ └── prometheus.yml
|
|
└── README.md
|
|
```
|
|
|
|
[_compose.yaml_](compose.yaml)
|
|
```
|
|
services:
|
|
prometheus:
|
|
image: prom/prometheus
|
|
...
|
|
ports:
|
|
- 9090:9090
|
|
grafana:
|
|
image: grafana/grafana
|
|
...
|
|
ports:
|
|
- 3000:3000
|
|
```
|
|
The compose file defines a stack with two services `prometheus` and `grafana`.
|
|
When deploying the stack, docker compose maps port the default ports for each service to the equivalent ports on the host in order to inspect easier the web interface of each service.
|
|
Make sure the ports 9090 and 3000 on the host are not already in use.
|
|
|
|
## Deploy with docker compose
|
|
|
|
```
|
|
$ docker compose up -d
|
|
Creating network "prometheus-grafana_default" with the default driver
|
|
Creating volume "prometheus-grafana_prom_data" with default driver
|
|
...
|
|
Creating grafana ... done
|
|
Creating prometheus ... done
|
|
Attaching to prometheus, grafana
|
|
|
|
```
|
|
|
|
## Expected result
|
|
|
|
Listing containers must show two containers running and the port mapping as below:
|
|
```
|
|
$ docker ps
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
dbdec637814f prom/prometheus "/bin/prometheus --c…" 8 minutes ago Up 8 minutes 0.0.0.0:9090->9090/tcp prometheus
|
|
79f667cb7dc2 grafana/grafana "/run.sh" 8 minutes ago Up 8 minutes 0.0.0.0:3000->3000/tcp grafana
|
|
```
|
|
|
|
Navigate to `http://localhost:3000` in your web browser and use the login credentials specified in the compose file to access Grafana. It is already configured with prometheus as the default datasource.
|
|
|
|
|
|
|
|
Navigate to `http://localhost:9090` in your web browser to access directly the web interface of prometheus.
|
|
|
|
Stop and remove the containers. Use `-v` to remove the volumes if looking to erase all data.
|
|
```
|
|
$ docker compose down -v
|
|
```
