Building

This repository uses Docker for building and deploying the application locally. It uses docker-compose to achieve this. To build simply run

docker-compose build

You can specify individual services to build or to start / stop as part of the docker-compose command, i.e:

docker-compose build api
docker-compose up postgres

Running

In order to run the application simply execute

docker-compose up

This will bring up all the necessary services for the UNI API to function. Currently these include:

• The Python API itself
• Redis cache
• Postgres container with the data modeling

Rebuilding the database

The PostgreSQL database works using volumes which means that the data will be persisted in between restarts. This also means that if there are changes to the model in the database we need to manually rebuild the image and remove the volume so that the new changes are applied. In order to do that you can use the following set of commands:

1. To remove data from tables (table structure will stay the same since it is tied to the image) you can simply run:

   docker volume rm uni-wtb_db-contents
   

2. To make sure the database is recreated so the changes are applied you need to remove and recreate the image you need to run above command and then:

   docker volume rm uni-wtb_db-contents
   docker image rm uni-wtb_postgres
   docker-compose build postgres
