## Compose sample
|
|
### Prometheus & Grafana
|
|
|
|
Project structure:
|
|
```
|
|
.
|
|
├── docker-compose.yml
|
|
├── grafana
|
|
│ └── datasource.yml
|
|
├── prometheus
|
|
│ └── prometheus.yml
|
|
└── README.md
|
|
```
|
|
|
|
[_docker-compose.yml_](docker-compose.yml)
|
|
```
|
|
version: "3.7"
|
|
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
|
|
```
