FEA505 - Configure scalable and resilient infrastructure using containerization
Feature ID FEA505
Subsystem the feature is part of EP05 - Frontend/Backend
Responsible person Matias Korpela
Status Implemented

Description

Through this functionality, our goal is to encapsulate our service within Docker, ensuring that both its dependencies and configuration are bundled together into a container image. The frontend and backend will have their own images.

ID Description
FUNC-REQ-C0006 You have to be able to dockerize the software

Preliminary user stories

  • US027 As a platform engineer, I want to set up a scalable and resilient infrastructure using containerization, such as Docker, to ensure easy deployment and management of the web app., Dockerize everything. #69

User interface mock-up

Implementation

Docker was used for containerization. Containers run at our own CSC instances. Architecture for CSC deployment can be seen on Architecture and Design
