Homer is a dead simple static HOMepage for your servER to keep your services on hand, from a simple yaml configuration file. We can use this app in order to have a homepage for all our services, apps and links of our server into one place, and edit only one yaml file. In order to run the app we need Docker installed in our system, as it is going to be run as a container.
