Your organization wants to implement an internal system for submitting different types of applications (for example: request for new equipment).
Each request must be approved by the manager.
Requests should be indisputable and immutable.
Example request and decision structure:
Request {userId, managerId, creationTime, requestContent}
Decision {managerId, Request, decisionResult, decisionTime}
JSON:
{
"userId": "",
"managerId": "",
"creationTime": "",
"requestContent": ""
}
{
"managerId": "",
"Request": {
{
"userId": "",
"managerId": "",
"creationTime": "",
"requestContent": ""
}
},
"decisionResult": "",
"decisionTime": ""
}
Each service is packaged as a separate container.
To run whole system you can use docker + docker-compose.
Prerequisites: local docker & docker-compose
To run application you simply execute command:
run.sh
Services are started with tty attached to current terminal.
To stop application just press:
Ctrl+C
