Missing "tini" executable in Docker

[jamietudor]

I'm trying to setup Teslamate in a Docker Container but I get the following error when trying to start up the Postgres container using docker-compose. I'm using the docker-compose.yml from the website:

Background task error for application_custom tesla: ERROR: for tesla_teslamate_1 Cannot start service teslamate: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "tini": executable file not found in $PATH:

I'm using a QNAP and I get the same error whether I use the command line to create the containers or the QNAP Container Station GUI.

Anyone come across this before?
