Overview
Current production Dockerfile run-time command for the container is yarn build-and-start, that is a parallel run of node server and vue-cli-service build --watch --mode production. This parameter will make the build process keep watching the folder waiting to rebuild the app on any change. I guess this is related with 2 needs, developing or the app itself need to rebuild to show some changes.

Presented Dockerfile just init the container with yarn start and removes tini, effectively using ~60 Mb of RAM (reduced from ~500Mb!), with no rebuilds. I restored my dashboard with ID and then created new items and everything seems to be working as it should, but no extensive testing has been done.
