Liquibase DevOps Homework

Please clone this repo. Do not fork unless you want others to potentially see your work.

Please ask questions. You can email me at [email protected].

The assignment is to troubleshoot the app locally, build the infrastructure, and deploy it.

Please create a NOTES.md with your thought process, troubleshooting, and solutions. The goal here is not to "weed someone out" but rather to see your thought process when dealing with a typical DevOps-y day :)

Task 1 - Application

The application is a simple to-do list app. There are bugs that need to be fixed:

1. The Dockerfile for the api (todo-api) is inefficient. Convert it to a multi-stage docker build and make it as efficient/small as possible. If done correctly the final image should be < 300 MB.
2. The docker-compose file in the root of the project has 2 bugs. Fix them. You should be able to run a docker-compose up to start the application. If the application is working you should be able to browse to http://localhost and create a to-do list.

Task 2 - Infrastructure Resources

The infrastructure should be written as code. Please create the following resources in the AWS free tier. Note that using existing public modules is perfectly acceptable:

• Elastic Load Balancer
• EC2 Instance
• Postgres RDS Database
• Any required security groups

Infrastructure Requirements

• The load balancer should only allow access to port 80.
• The EC2 instance should only allow access from the load balancer
• The database should only allow access from the EC2 instance
• We should be alerted if the ELB health check is not passing.

Task 3 - Application Deployment

Deploy your docker containers to the EC2 instance created above.

Task 4 - Production Database

• The database is currently a local postgres docker container. This is fine for local development, but not suitable for production. Make any necessary changes required to use the RDS Database you created instead.
