Easier local deployment

[EdwinB12]

• Rather than having the manual developer doc instructions, can we wrap everything inside a docker container and single executable script?

Below is a simple script that I am using to deploy a local instance of the app. Also offers the option to restart the database. I don't think we should commit this to the repo but could be handy for development.

#!/bin/bash

# REMEMBER TO ACTIVATE YOUR PYTHON VIRTUAL ENVIRONMENT BEFORE RUNNING THIS SCRIPT! 
# THIS SCRIPT SHOULD BE RUN FROM THE ROOT LEVEL OF THE REPOSITORY

# Load the environment variables
source .secrets/dtenv_localdb.sh

# Take in an argument called 'restart-db' to optionally restart the database
if [ "$1" == "restart-db" ]; then
    echo "Restarting the database"
    # stop and delete server container
    docker stop $DT_SQL_DBNAME
    docker rm $DT_SQL_DBNAME

    # start the postgres docker container
    docker run --name $DT_SQL_DBNAME -e POSTGRES_PASSWORD=$DT_SQL_PASS -p 5432:5432 -d $DT_SQL_USER

    # create the database
    createdb --host $DT_SQL_HOST --username $DT_SQL_USER $DT_SQL_DBNAME -W 
fi

# Run the backend. This will run the backend in the background to leave the terminal open for the frontend. 
cd dtbase/backend
./run_localdb.sh &

# Run the frontend
cd ../webapp
./run.sh

# NOTE: THE BACKEND WILL CONTINUE TO RUN IN THE BACKGROUND AFTER THE TERMINAL IS CLOSED. 
# TO FIND AND KILL THE BACKGORUND PROCESS, RUN ps TO SEE ALL RUNNING PROCESSES AND THEN KILL THE PROCESS WITH IT'S PID ID WITH KILL <PID>
