I wanted to play a little bit with my home automation system and needed to have an easy interface to control my sonos environment. After some googling I came across sonst-http-api by jishi (https://github.com/jishi/node-sonos-http-api) and have decided to give it a try. But where should I run this? Setting up another Raspberry Pi (the exactly always gets a corrupted SD card at the worst point in time or my NAS to which I have migrated all my tiny home apps)? The answer is simple... Let's go the NAS route.

To set this up, I wanted to achieve the following

So I logged in to my QNAP NAS and started the Container Station App.

Then I have selected Container → Create (hope this is the translation they have used for erstellen).

Then add the following data:

We want to pull it from Docker Hub and I decided to use the "node" image that contains everything for node.js

Specify any container name that you want to use, I decided to use the standard network node (NAT) and expose the internal TCP port 5005 to the host using the same TCP port.

After that, I have modified the entrypoint and the command. The entrypoint is the first command that is executed (now: sh -c) and the "command" is an additional command or parameters. In this case:

Now you can apply these settings and click on next to finalize everything. Then the container automatically starts.
