Apart from the services, the Docker Compose file also defines a volume named `grafana-data` to persist the Grafana data and a network named `go-network` to connect the services together. You have created a custom network `go-network` to connect the services together. The `driver: bridge` field specifies the network driver to use for the network.

## Building and running the services

Now that you have the Docker Compose file, you can build the services and run them together using Docker Compose.

To build and run the services, run the following command in the terminal:

```console
$ docker compose up
```

The `docker compose up` command builds the services defined in the Docker Compose file and runs them together. You will see the similar output in the terminal:

```console
 ✔ Network go-prometheus-monitoring_go-network  Created                                                           0.0s 
 ✔ Container grafana                            Created                                                           0.3s 
 ✔ Container go-api                             Created                                                           0.2s 
 ✔ Container prometheus                         Created                                                           0.3s

Title: Building and Running Docker Compose Services

Summary

This section describes how to build and run the Docker Compose services using the `docker compose up` command. It also shows example output in the terminal, demonstrating the creation of the network and containers for Grafana, the Go API, and Prometheus. The output includes debug information from the Go API, such as registered routes and warnings about trusting all proxies.
