• Learn about How to Dockerise an application.

• Learn about Mutli-stage Dockerfile.

• Learn about Dockerfile best practices.

Problem Statement

Create Dockerfile for the REST API.

Expectations

The following expectations should be met to complete this milestone.

• API should be run using the docker image.

• Dockerfile should have different stages to build and run the API.

• We should be able to inject environment variables while running the docker container at runtime.

• README.md should be updated with proper instructions to build the image and run the docker container.

• Similarly appropriate make targets should be added in the Makefile.

• The docker image should be properly tagged using semver tagging, use of latest tag is heavily discouraged.

• Appropriate measures should be taken to reduce docker image size. We want our images to have a small size footprint.
