Hi I'm trying to use  
image: corbosman/pigpiod daemon

in docker compose and find that the digital output works reliably. The input nodes rarely work. I am testing directly on the PI4 with 3.3V directly to the pin. Prior to migrating to Docker and Dashboard 2 I had no problems. Please help I have spent hours on this.  
thanks

Are you shorting the pin to ground for the other state?  
Alternatively have you got a pull down resistor on the pin. Either the internal pulldown if available, or an external one if not.

I'm using an internal pulldown. Sometimes it registers the logic 1 but mostly not. I have set up 6 GPIO input pins and they all behave erratically. I had suspected maybe an interaction with other docker containers and maybe the use of port 888 but I have stopped them all.

I don't know what might be the problem then, sorry.
