The service that we’re going to build is a simple bank. It will provide APIs for the frontend to do the following things:

• Create and manage bank accounts, which are composed of the owner’s name, balance, and currency.
• Record all balance changes to each of the accounts. So every time some money is added to or subtracted from the account, an account entry record will be created.
• Perform a money transfer between 2 accounts. This should happen within a transaction, so that either both accounts’ balances are updated successfully or none of them are.

It should use a Unix-style line endings instead of Windows. This problem occurs some errors when running sh file in docker. You should run the following command before cloning the repository:

git config --global core.autocrlf false Then clone the repository and proceed.

There are 3 ways written in Makefile to run the project

• Run SimpleBank using POSTGRES CONTAINER && REDIS CONTAINER && make server to start server
• Run SimpleBank using DOCKER NETWORK to connect 3 STAND-ALONE CONTAINERS (postgres container + redis container + app container)
• Run SimpleBank using DOCKER COMPOSE UP
