Run the following command to start the frontend, backend containers and DB container(but now just the backend and db container):
sudo docker-compose up -d --buildEvery time you change the DB data ex: add a new table, add a new column, change a column type, add a new data(order..), etc. You need to run the following command to update the DB backup file. DB is built up based on the data in the backup file.
cd backend/scripts/testDB
sh backup-db.shFor a full Kafka setup demoed previously, please refer to this.
Env file is in the line group. Copy and paste the env file to the root dir layer~~
