Multiple remote hosts support - Feature request

[badarotti]

Hi,

I know this would require a decent amount of re-architecture, but I would like to throw this in here in case it's convenient to implement in the future.

One instance of Doku can access and report the disk usage of multiple remote docker instances. This would be a great single pane of glass for all instances as well as minimize the installation and upgrade headaches. I have 3 instances in my home lab and multiples instances at work.

This how Dozzle does it as an example.

Thanks a lot for the great app.
