[DONE - ARCHIVED FOR REFERENCE] Setup Prod instance - Dokku

[MatoPlus]

Install all required dependencies to run backend/frontend/db, check our dockerfiles for reference on what to install.

We would like Postgresql 12.11 and Node 14.5.5 as we would like a DB service and a place for our Node (Graphql) backend service to run with versions as similar to our development environment as possible. For your information, we use the docker images node:14.15.5-slim for our local backend container and postgres:12-alpine for our db container.

Action: create bash script to install all dependencies

Docker images:
https://github.com/nodejs/docker-node/blob/main/14/buster-slim/Dockerfile#L20
https://github.com/docker-library/postgres/blob/master/12/alpine/Dockerfile

initial server setup guide: https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-20-04 might help.

For an Apache webserver server, which would be a guide like this: https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-apache-in-ubuntu-20-04.

The flow of the bash script

1. Add non-sudo user
2. Install needed deps to run all services

We want to setup dokku on the machine and run all the required containers in the VM: https://dokku.com/docs/getting-started/installation/

To make this closest to prod as possible, we want to deploy just backend and db in vps, frontend on firebase hosting
