 In order to execute the code example, you need to specify `MONGODB_URI` environment variable to connect to a MongoDB cluster. If you don't have any you can create one by signing up [MongoDB Atlas Free-tier M0](https://docs.atlas.mongodb.com/getting-started/).

+1. Build Docker image with a tag name. Within the top level directory execute:
