Mosquitto had errors too:

Error saving in-memory database, unable to open /mosquitto/data/mosquitto.db.new for writing

Solved it with chown -R 777 volumes/mosquitto/* which feels very wrong...

pi@raspberrypi:~/IOTstack $ ls -la volumes/mosquitto/

Just realised the build script wasn't accepting "Y" for chown -R 1883:1883 ./volumes/mosquitto so I opened another issue just for this
