+## Compose sample
+### Prometheus & Grafana
+
+Project structure:
+```
+.
+├── docker-compose.yml
+├── grafana
+│   └── datasource.yml
+├── prometheus
+│   └── prometheus.yml
+└── README.md
+```
+
+[_docker-compose.yaml_](docker-compose.yaml)
+```
+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.
+
+![page](output.jpg)
+
+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
+```
