[00p] Getting started [this archive]APIAPI In order to solve the tasks, you need to have Docker installed, or you need to use Play with Docker, as described in lab 4. text/html 2025-05-21T08:38:33+03:00 http://ocw.cs.pub.ro/courses/ii/labs/s2/05/tasks/01?rev=1747805913&do=diff 01. [30p] Running a multi-container application Subtasks * based on the sources and the Dockerfile in the backend folder from the lab archive, build an image with the name lab5-api-image * create a bridge network called lab5-db-network * create another bridge network called lab5-adminer-network * create a volume named lab5-db-volume * from the parent folder of backend, launch a container in the background for a database with the following features: * a bind mount will be attached … text/html 2024-04-29T19:31:02+03:00 http://ocw.cs.pub.ro/courses/ii/labs/s2/05/tasks/02?rev=1714408262&do=diff 02. [10p] Testing a web application using Postman The application started earlier is a web application that does not have a graphical interface (i.e., a frontend). For this reason, it can only be tested by sending HTTP requests using a tool such as Postman. We will now show how to use Postman to connect to a web application backend. text/html 2024-04-29T18:43:15+03:00 http://ocw.cs.pub.ro/courses/ii/labs/s2/05/tasks/03?rev=1714405395&do=diff 03. [10p] Testing for data persistence Subtasks * stop and delete the three containers started at exercise 1 * start them again using the same commands given at exercise 1 * send a POST request using Postman and verify that the book you added at exercise 2 is still in the library text/html 2024-04-29T19:32:11+03:00 http://ocw.cs.pub.ro/courses/ii/labs/s2/05/tasks/04?rev=1714408331&do=diff 04.
