Our Engineering team have produced an application which now needs to be automatically built and deployed using a fully automated CI & CD Process. The team have asked us to help with this solution.

You have been asked to create a docker file which will run the application which is written using react and the lts node version node 14.15.1. The file should:

• Install node modules within the Docker image only
• Run the application (uses npm start) exposed on port 3000

The result will consist of:

• Docker file with the necessary steps

Create a build and release pipeline which:

• Builds the code appropriately using npm run build
• Builds the Docker image
• Deploy the application to three environments dev, qa and prod

The result will consist of:

• CI&CD code as yaml using an an Application Lifecycle Management tool of your choice (preferably AzureDevOps)
• Dry-run file in md format wherever the CI/CD code has not been provided as code.
• Documentation and explanation where necessary, committed to this repo.
