Our production environments utilise AWS cloud platform with the infrastructure being created and controlled by Hashicorp's Terraform. Our deployment process takes the app code repository, generates a series of docker images which are then placed into AWS Elastic Cluster Service.
This repository contains a Go application (with ./app folder) that acts as an API; it is configured to respond on port 8080 and has two endpoints (/ and /status) that return json content.
The /status endpoint returns different content and http response code depending on the value of an environment variable called APP_STATUS. When APP_STATUS=OK the /status endpoint will return a 200 code and message, otherwise it will return a 500 code.
We would like you to create a fork of this repository which expands this code to provide a way to create a working docker image from this application with both endpoints returning successful response codes.
Please include an updated README with steps to produce and run the docker image.
Do not worry if you are not able to fully complete the task, we are more interested in your approach then a perfect solution.
To help guide you in this task, we've outlined some typical steps (in no particular order) that would be needed.
- Creating a Dockerfile
- Building the Go app
- Mapping ports
- Setting up Docker on your local machine
- Passing environment variables
