Well the webui provides me with a list of containers, whether they're running or not, the ports that are opened by the containers. There's Stacks which are basically Docker Compose files in a neat UI. The ability to move these stacks to other instances. There's the network options and ability to make more networks, the files that are associated with the containers.
And not just for the instance I'm in, but for all the instances I've connected.
In my previous experience with Docker these are all things that I need to remember code to find, meaning I most often have to Google the code to find out what I'm after. Here is neatly packaged in a web page.
Oh and the logs, which are really useful when tinkering to try get something up and running
It's on my list. I've played with DuckDNS in my time with Home Assistant, I used to get external access through it and Nginx and honestly loathed it. I was SO HAPPY when I got Cloudflare working.
I am now working for a global company and I've noticed that the intranet here doesn't have valid SLL certificates at all, which I know is a security concern, so with a bit of research and tinkering I believe I can become more knowledgeable about this kind of thing than the IT manager of our factory. Might help me work up to a position that isn't on a line anymore.
So yeah, it's on my list.
