Summary
In this chapter, we set up Prometheus on Compose and made it feasible to collect and receive metrics and raise alerts. By doing so, the multi-container application we created using Compose could submit metrics. This enabled us to monitor our application and get alerted if something was wrong. All of this has been made possible by changing our Compose installation and simply adding some extra configuration files using volumes on Compose. One issue with the preceding approach is the lack of flexibility. We need to have all services in one file running regardless if we only want to run individual components.
In the next chapter, we will evaluate how we can modularize our Compose application and run it on multiple files.
