Scania Test

1. Containerize an Application Using Docker:

The application has been written in Python with Flask framework. The Dockerfile is written as a multi-stage build to reduce the image size and enhance security.

2. Set Up Backstage:

3. Integrate Docker with Backstage:

• Created backend API to trigger GitHub actions (in Node.js)

  yarn add @octokit/rest
  -triggerWorkflow.js
  

• Creating a Deploy Component: This component will include a form where users can specify the necessary details for triggering a GitHub Actions workflow (e.g., repository name, workflow ID).

  • DeployComponent.ts

• Created a Custom API Ref: Defined a custom API in the Scania plugin to abstract the communication with the backend.

  • api.ts

• Added an API in the backend to list the deployed images:

  • router.ts

• The backend component in Backstage to list all images:

  • DockerHubImagesComponent.tsx

• Component to run the image locally:

  • RunDockerComponent.tsx

• Backend part part of run image locally:

  • server.js

4. Create a “CI/CD Pipeline”:

Used GitHub Actions to build the docker image and push it to Docker Hub.

Deploy the Container:

Used Azure DevOps pipeline to build and push it to Azure Container Registry and deploy it to Kubernetes cluster. Manifest files and Azure DevOps pipeline script are added.

• DeploytoAzureK8s.yml
• deployment.yml
• service.yml
