I'm not an unbound expert, but as far as I understand MatthewVance's image, unbound is already configured properly: https://github.com/MatthewVance/unbound-docker/blob/master/1.17.1/data/unbound.sh. I didn't want to go into detail how pi-hole or unbound works, since I think there is enough documentation on that.

I am successfully running pihole on a different machine, but am planning to migrate to a new docker host. I figured this would be a good time to configure pihole with unbound. I am attempting to run unbound in a docker container running on Opensuse leap and I am using this docker image.

You can also use Unbound for recursive DNS in a docker container: https://github.com/MatthewVance/unbound-docker

I found that Nick O'Leary (founder of Node-RED and the great guy that he is..) already did some research on this, I just had to bring this all together.

I don't use node-red, but I guess they use the node-red user in shell and overriding the process owner causes some issues with that. You can add an issue to their repository if you want.

Standard practice with Node-Red lets the user add dedicated flows and dependencies via the npm install command-line. However within the Node-Red-Docker Repo Wiki, you can also add these flows/dependencies via a dedicated package.json.
