Swarm
If you utilize docker swarm, this can still be used.
- Install Dockwatch on each of the swarm nodes
- Pick whichever instance you want to be your "main" instance
- Get the url and apikey from each node instance and add them to the servers section in the settings
Now you will have a drop down menu above the navigation that allows you to hop between each Dockwatch instance and control each one from a single interface
