Gives you a nice dashboard that you can configure however you like. It includes integration with a ton of existing services, as well as docker.
My setup:
Clicking on each service will open it's respective url.
The 'healthy' indicator at the top right of each service is it's container health. Clicking on that will expand to show cpu, ram and network usage. Some of these services/docker hosts are on separate machines; it all integrates together nicely.
This is what I use. I tried other ones, but this one is simple to set up and edit. It's very clean and has a ton of widgets for services. I would like it to have a login option, but that isn't a deal breaker.
Yeah; the lack of authentication options is a bit of a bummer if you're going to expose/share this page. There is always basic_auth in nginx or whatever proxy you're using if you really want.
There are a bunch of other static site generators as well. They're mostly targeted at blogs and whatnot, but maybe that's a good thing if you want to leave some instructions/documentation about each one.
