Create all the necessary environment variables

Create a google cloud api key file. Download it into the env folder of the backend. If that doesnt exist, create it.

Also download the pem file of the aws ssh key of the ec2 instance. Then:

Add to the environment file .env the following entries:

POSTGRES_USER=<<enter user>>
POSTGRES_PASSWORD=<<enter password (only utf-8)>>
POSTGRES_DB=<<enter db name>>
PGADMIN_DEFAULT_EMAIL=<<enter random email>>
PGADMIN_DEFAULT_PASSWORD=<<enter random password>>
GOOGLE_CREDENTIAL_FILE=<<name of the json key file from google cloud>>

Install the packages

cd backend && python3 -m venv .venv

Then activate that environment. In windows its different than in linux or mac-OS. in any case in the latter it should be like:

source .venv/bin/activate

And then

pip install -r requirements.txt

Connecting to ec2 instance

connect to instance:

ssh -i "keyfile.pem" ubuntu@ip_address

update and upgrade

sudo apt update
sudo apt upgrade -y

reboot instance

sudo apt install docker.io git -y

sudo systemctl start docker
sudo systemctl enable docker

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

Other

pip list --not-required | awk '{print $1 "==" $2}' > requirements.txt

docker exec -it backend cat /var/log/apache2/error.log

uploads to the flask server can be tested with

curl -X POST -F "file=@/home/leonhard/Projects/Hallein/minting-objects-game/backend/img/SocksOrNot.jpg" http://localhost:5000/upload

to test the createProductSet route (change the product_set_id!)

curl -X POST -H "Content-Type: application/json" \
-d '{"product_set_id": "something", "product_set_display_name": "pumps all the way"}' \                                         
http://localhost:5000/vision/createProductSet

to test creation of products:

curl -X POST -H "Content-Type: application/json" -d '{"product_id":"squashes", "product_set_id":"veggies", "product_display_name": "something other than pumpkins"}' http://localhost:5000/vision/createProductAndAddToProductSet

to test the uploading of an image to a product (change the filename from pumpkin4 to something higher and dont forget to have that file created in you local directory, i.e. not leonhard)
