Local Dev setup

[fabriph]

Hey, thanks for writing this, super helpful! I'm trying to setup my local dev environment so I can poke at it. Did I understood correctly that I can run it without HA? I'm trying to run docker standalone but it's failing to resolve host supervisor. This is what I've so far:

Build image (AFAIK this works fine):

debian:~/dev/hassio-addons/kasa-camera$ sudo docker build . -t kasa-camera --build-arg BUILD_FROM=hassioaddons/base:latest

Run image:

debian:~/dev/hassio-addons/kasa-camera$ sudo docker run -p 3000:3000 kasa-camera
