CMPE 272 Hello World Microservices Application

This application contains three microservices using Python and Flask. Two of the microservices returns a simple message: "Hello" and "World". The third microservices takes these two output and combines them together to output "Hello World". Each service is containerized using Docker and deployed onto a Kubernetes cluster using Minikube.

Requirements

This application uses the following (at the minimum):

• Python 3.9
• Requests 2.31.0
• Flask 2.0.2
• Werkzeug 2.0.2
• Docker
• Minikube

To run the application:

1. Ensure that the above required tools are downloaded and setup.
2. Clone the Github repository and cd into the repository.
3. Run the setup.sh script. (NOTE: This is a bash script)
4. The helloworld application should automatically open in a browser when the script is finished. If not, the terminal should display what IP address the application is running at.

Other Notes:

• The above steps should be ran on a CLEAN build. (i.e. no previous instances of the application's docker containers, images, minikube clusters)
• The IP addresses used in helloworld.py are hardcoded, assuming that those are given when the hello and world microservices were deployed separately.
• Link to DockerHub repo containing the images: https://hub.docker.com/r/denisegip/cmpe272
