Homeworks for Highload Architecture course in NaUKMA

Branches

1. main - main for CI (Lab 5)
2. feature-lab5-splitted-actions - develop CI feature
3. feature-lab4 - for Lab 4
4. deploy - for extra deploy task (almost work)

Lab 4

Task

1. Make two API endpoints: GET and POST
2. For read action you should use cache
3. For post action you should use queue
4. Result must be wrapped in docker-compose with instructions to deploy.

How to use?

1. Rename .env.example to .env
2. Use docker compose up to create instances
3. Wait for initialization
4. After it you can access API with localhost:4000
5. Also you can try use --scale {service_name}={scale_number} to increase number of containers for some services.

Service names: read, write, worker

Just copy docker compose up --scale worker=3 --scale read=2 --scale write=2

API

1. /get - returns all books (with caching)
2. /get/<id> - returns book by id (with caching)
3. /write/add - create new instance (with queue)
4. /write/edit/<id> - edit instance (with queue)
5. /write/check_status/<job_id> - check job status

Testing

You can use configured postman collection for test purpose.

P.S. Postman sometimes ignore variable assigning, check it if error with request occur.

Lab 5

Task

Create a CI using simple GitHub Flow around your previous project (API for managing books):

1. Use docker as a build environment within GitHub Actions Stages: build, test (pls write some tests for your app please, at least 2)
2. Apply actions automaticaly on merge in master (main) branch from your feature branch
3. Use GitHub flow

Exstra Task

Create CD (Continuos Delivery) job based on GitHub Actions, whitch will deploy your app to your AWS infrastructure (+10 points to your score)
