Docker image size

[janjbrand]

Thanks for developing Dockermon! Something I noticed is that the image size of de docker image is quite large (almost 500 MB, arm tag). It seems to be a lot for what it does. Is it possible to reduce the image size? I am running it on a Raspberry Pi and have to look after disk usage.

Thanks @janjbrand

Yep its a good idea. The base image is balenalib/raspberrypi3-node:10.16 (on the edge tag at least). I'll have to experiment with other base images to get the right balance of Node and Docker support.

As a heads up, the release arm tag is 172mb vs the edge-arm tag (which will make up the next release) as 99.2mb (compressed). So hopefully the image has already started to be reduced, but I'll leave this open to see if I can work towards reducing this even further in the future.
