Preparation

Execute the next commands to create the image and the network

docker build . -t vendor-machine-cli -f docker/php/Dockerfile
docker network create vendingmachine

Installation

docker run --rm --network vendingmachine -v $(pwd):/app -w /app  vendor-machine-cli composer install

Test

docker run --rm --network vendingmachine -v $(pwd):/app -w /app  vendor-machine-cli php bin/phpunit

Execution with main command

docker run --rm --network vendingmachine --network vendingmachine -v $(pwd):/app -w /app --interactive --tty vendor-machine-cli php bin/console app:machine-vending-start

You can execute all the commands after the prompt >

Command	Description
1	Add 1 to user credit
0.5	Add 0.5 to user credit
0.25	Add 0.25 to user credit
0.1	Add 0.1 to user credit
RETURN-COIN	Returns the coins that the user had inserted
GET-WATER	Make the purchase of the WATER product
GET-JUICE	Make the purchase of the JUICE product
GET-SODA	Make the purchase of the SODA product
SERVICE	Displays a summary of the machine's inventory and allows you to set the amounts of coins and products
EXIT	Exits the operating console of the machine

The commands relative to Coins are based on the parameter imports of services.yaml

The commands relative to Products are based on the parameter products of services.yaml

Execution with individual commands

You can also run the operations individually

docker run --rm --network vendingmachine -v $(pwd):/app -w /app --interactive --tty vendor-machine-cli php bin/console app:machine-vending-insert-coin 0.5

docker run --rm --network vendingmachine -v $(pwd):/app -w /app --interactive --tty vendor-machine-cli php bin/console app:machine-vending-return-coin

docker run --rm --network vendingmachine -v $(pwd):/app -w /app --interactive --tty vendor-machine-cli php bin/console app:machine-vending-get-product WATER

docker run --rm --network vendingmachine -v $(pwd):/app -w /app --interactive --tty vendor-machine-cli php bin/console app:machine-vending-service

Status vending machine by http

If you want to check the inventory of the vending machine you can execute:

docker run --rm --network host -p 8000:8000 -v $(pwd):/app -w /app  vendor-machine-cli php -S localhost:8000 -t public/

And then execute the next URL in your browser:

http://localhost:8000/status

You will get something like that:

{"products":[{"WATER":1},{"JUICE":2},{"SODA":3}],"coins":[{"0.5":4},{"0.1":5},{"0.25":6},{"1":7}],"credit":[[0.5]]}

Data visualization

To use this functionality you need to change the property dataMiningEnabled to true in services.yaml

Next execute the next command:

docker-compose -f docker/docker-compose.yml up

Enter to:

http://localhost:5601/

Import etc/kibana/dashboard_vending_machine.ndjson to Management -> Saved Object -> Import

An example of visualization.

Improvements

• phpunit -> Check the events created
• phpunit -> Check the messages of the exceptions
• phpunit -> Check elastic
• Protect by token the status endpoint
• Create an API for all the operations in the vending machine
• Create a UI to manage the API
• Add Products and Coins dynamically
• New repositories (redis, mongo, ...)
