#### General ##### Check the Repo content A `README.md` file and all files used to create, delete and manage the student infrastructure must be submitted in the repo. ###### Are all the required files present? ###### Was the `.env` file excluded from the git files? ###### Are all pushed files in the repo clean of any credentials or passwords? ##### Ask the following questions to the group or student: ##### What are containers and what are their advantages? ##### What is the difference between containers and virtual machines? ##### What is Docker and what is it used for? ###### Did the student reply correctly to the questions? ##### Open and read the `README.md` file provided by the student. ###### Does the `README.md` file contain all the required information to run and manage the solution (prerequisites, configuration, setup, usage, etc)? #### Check the student infrastructure: The student must implement this architecture: ![architecture](../pictures/architecture.png) ##### Run the student infrastructure: ```console user:~$ docker-compose up <...> inventory-database ... done billing-database ... done inventory-app ... done billing-app ... done RabbitMQ ... done api-gateway-app ... done <...> user:~$ ``` ###### Does the student architecture reflect the infrastructure enforced by the subject? ###### Does the infrastructure start correctly? ##### Ask the following questions to the group or student ##### What is a microservices' architecture? ##### Why do we use microservices architecture? ##### What is a queue and what is it used for? ##### What is RabbitMQ? ###### Did the student reply correctly to the questions? #### Verify the Dockerfiles: ###### Is there a Dockerfile for each service? ###### Are all Dockerfiles based on `Debian` or `Alpine`? ###### Are Dockerfiles or any other solution files free from sensitive data (sensitive data should only exist in `.env` file)? ##### Ask the following questions to the group or student ##### What is a Dockerfile? ##### Explain the instructions used on the Dockerfile. ###### Did the student reply correctly to the questions? #### Check the Containers: ```console user:~$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES <...> inventory-database <...> <...> <...> 5432/tcp inventory-database <...> billing-database <...> <...> <...> 5432/tcp billing-database <...> inventory-app <...> <...> <...> 8080/tcp inventory-app <...> billing-app <...> <...> <...> 8080/tcp billing-app <...> RabbitMQ <...> <...> <...> 5672/tcp RabbitMQ <...> api-gateway-app <...> <...> <...> 0.0.0.0:3000->3000/tcp, :::3000->3000/tcp api-gateway-app user:~$ ``` - `inventory-db container` is a SQL database server that contains your inventory database, it must be accessible via port `5432`. - `billing-db container` is a SQL database server that contains your billing database, it must be accessible via port `5432`. - `inventory-app container` is a Node.js server that contains your inventory-app. It will be connected to the inventory database and accessible via port `8080`. - `billing-app container` is a Node.js server that contains your billing-app. It will be connected to the billing database and consuming the messages from the RabbitMQ queue. It will be accessible via port `8080`. - `rabbit-queue` is a RabbitMQ server that contains the queue. - `api-gateway-app container` is a Node.js server that contains your api-gateway-app. It will forward the requests to the other services and it's accessible via port `3000`. ##### Check the Container restart policy: ```console user:~$ docker inspect -f "{{ .HostConfig.RestartPolicy }}" {on-failure 0} user:~$ ``` ###### Do all containers have the correct configuration? ###### Are the containers configured to restart in case of failure? #### Check the Docker volumes: ```console user:~$ docker volume ls DRIVER VOLUME NAME <...> inventory-database <...> billing-database <...> api-gateway-app user:~$ ``` - `inventory-database volume` contains the inventory database. - `billing-database volume` contains the billing database. - `api-gateway-app volume` contains the API gateway logs. ###### Do all volumes have the correct configuration? ##### Ask the following questions to the group or student ##### What is a Docker volume? ##### Why do we use Docker volumes? ###### Did the student reply correctly to the questions? #### Check the solution network: ###### Is the connection to the api-gateway-app the only one exposed from outside of the Docker host? ##### Ask the following questions to the group or student ##### What is the Docker network? ##### Why do we use the Docker network? ###### Did the student reply correctly to the questions? #### Check the Docker images: ```console user:~$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE inventory-database <...> <...> <...> <...> billing-database <...> <...> <...> <...> inventory-app <...> <...> <...> <...> billing-app <...> <...> <...> <...> RabbitMQ <...> <...> <...> <...> api-gateway-app <...> <...> <...> <...> user:~$ ``` ###### Is there a Docker image for each service with the same service name? ##### Ask the following questions to the group or student ##### What is a Docker image? ##### Why do we use Docker images? ###### Did the student reply correctly to the questions? #### Inventory API Endpoints ##### Open Postman and make a `POST` request to `http://[GATEWAY_IP]:[GATEWAY_PORT]/api/movies/` address with the following body as `Content-Type: application/json`: ```json { "title": "A new movie", "description": "Very short description" } ``` ###### Can you confirm the response was the success code `200`? ##### In Postman make a `GET` request to `http://[GATEWAY_IP]:[GATEWAY_PORT]/api/movies/` address. ###### Can you confirm the response was success code `200` and the body of the response is in `json` with the information of the last added movie? #### Billing API Endpoints ##### Open Postman and make a `POST` request to `http://[GATEWAY_IP]:[GATEWAY_PORT]/api/billing/` address with the following body as `Content-Type: application/json`: ```json { "user_id": "20", "number_of_items": "99", "total_amount": "250" } ``` ###### Can you confirm the response was success code `200`? ##### Stop the billing-app container ###### Can you confirm the `billing-app` container was correctly stopped? ##### Open Postman and make a `POST` request to `http://[GATEWAY_IP]:[GATEWAY_PORT]/api/billing/` address with the following body as `Content-Type: application/json`: ```json { "user_id": "22", "number_of_items": "10", "total_amount": "50" } ``` ###### Can you confirm the response was success code `200` even if the `billing_app` is not working? #### Bonus ###### +Did the student use his/her own `crud-master` solution? ###### +Did the student add any optional bonus? ###### +Is this project an outstanding project?
