docker_broker

Build and start docker container with:

docker-compose up --build

Wait initialization. When it's done you will see a message " * Running on http://127.0.0.1:5000"

Test a server with a Curl from container CLI.

Curl requests will return you a transaction ID.

1. Put 1000.0 credits on to a client's account with id 1

curl "http://127.0.0.1:5000/1/1000.0/put"

2. Withdraw 600.0 credits from the same client

curl "http://127.0.0.1:5000/1/600.0/withdraw"

3. Try to withdraw another 600.0 credits from the same client

curl "http://127.0.0.1:5000/1/600.0/withdraw"

The last request will be cancelled because of low credits.

Look at result in a Postgre database

Use db's container CLI.

1. Connect to the database

psql postgres://postgres:pg@localhost:5432/accounts

2. Look at the history table

SELECT * FROM history;

There are two successfull transactions and one cancelled.

3. Look at the accounts table

SELECT * FROM accounts;

There are 400 credits on the account of a client with ID=1.
