Running AI6VN's kiwiwspr.sh in a Docker container
Hello,
I have just begun running AI6VN's `kiwiwspr.sh` in a Docker container. (Thank you, Robert, for the script. Fantastic work!).
The solution is particularly useful if you intend to run the monitor in the cloud and/or if you want to do it without installing anything on your machine (except for the Docker engine, of course!).
Here is my Dockefile:
- no need to install anything (except for Docker, if you don't have it already)
- integrate WSPR monitoring on your kiwi by running a single command
- runs on on Linux, macOS or Windows - unmodified
- easily runs in the cloud
Cons:
- Needs the Docker engine
- Will run under UTC time
- more disk space is needed
To-do:
- Make wsprd run on Alpine instead of Debian
- Remove x11 and all of its dependencies
- Test if the image can run on a Raspberry PI
I hope this can be of some interest to someone.
Alain

I wrote my script in bash and have it running natively on a Pi, i86 Debian and Max OSX. My primary goal for further development work is additional functionality, but let me know if I can make changes to make it more portable as well.

Yes I noticed the effort to have the daemon run on Macs. Yet, I thought that running it with a single command and without installing anything was a nice thing to have.
I didn't want to publish my own image but if I had anyone could have run your script by running a single command, literally in one second.
A change that would be definitely appropriate for running this in a container would be the possibility of starting the service without daemonizing it and (for extra points) having the output streamed to STDOUT and STDERR rather than written to logfiles.
