How do I install a second instance of an applications?
There may be some use cases where you may wish to run a given application twice, with separate appdata settings, ports, etc.
Assuming that the container runs as network type: Bridge,
On the Apps Tab (you do have Community Applications installed don't you?),
Go to Settings - Enable Reinstall Defaults
Go to the Installed Apps section,
Reinstall using default values the application you want to run another instance for
Change the name of the application, along with assigning it different ports, paths (you may need to show advanced settings to see the appdata (/config) path)
Hit Apply
If the application runs as network type: Host, you will do all the same as above, but you will need to switch network type to be Bridge, and add in all of the applicable ports and reassign them as needed. (ie: check with the support thread and/or the project URL to determine which ports need to be defined
Alternatively, (under either Bridge or Host network types), if you are running unRaid 6.4+, then you can also assign the new instance a different IP address and keep the ports the same (bridge mode), or not define them at all (host mode). But you will still have change the name of the application and set the appdata (/config folder) accordingly
