Run the simplified app in docker

To run the most basic configuration of the app + postgres db, You can use docker-compose.yml. For the app to work correctly when containers are up please create and run migrations from the localhost or add script to do so.

Command : "docker-compose up" or "docker-compose up --build" if You want to rebuild this app image (if it is present).

To run everything in docker You have to adjust docker-compose.yml

Deploy app to kubernetes

To create deployment and service You can use express-deployment/service.yaml with command "kubectl apply (-f FILENAME | -k DIRECTORY)" If You want deployment/service to work remember to use proper name whe creating and pushing app docker build and to properly set Prometheus port to properly scrap metrics (default prometheus port is 8080 when deployed through helm-chart).
