nlintas/java_cloud_microservices_project

Based on coursework which will implement microservices, Netflix Eureka, SpringBoot, Kubernetes and Docker container technologies in Java. The aim is to be able to make file conversions built on microservice architecture.

Microservices Based File Converter

In this project several technologies will enable the creation of an application that will allow for independent microservices to handle file conversion. These will coordinate initially with a Netflix Eureka server and then be Dockerized and managed by Kubernetes and Google Cloud.

Run Local Build Instructions

1. Initialize the Eureka server.
2. Initialize the conversion microservice.
3. Initialize the web server.
4. Open all web pages through the ports provided from Eureka (Eureka is at port 8761).
   1. If an error occurs where no conversion/text to pdf microservice is available wait for a minute so that it registers with Eureka and try again.

Run Locally Docker Compose Instructions

Run from the root directory the test_local_docker_compose.sh file. Warning! Be aware that the script contains a docker rmi command that removes all images with names eureka, conversion_service and client.

Rolling Update Instructions

1. Make sure pods exist already and their status using kubectl get pod
2. Run from the root directory the rolling_update.sh file

Warning! Be aware that the script contains a docker rmi command that removes all images with names eureka, conversion_service and client.

Remove Deployments & Billing on Google Cloud

Follow the steps:

1. Google Official Docs
2. Disable all services on Google Cloud Platform.
   1. Open the hamburger menu
   2. Select APIs & Services
   3. Select Enabled APIs & Services
   4. Sort by most Requests (arrow points down)
   5. Click on each service with any entries
   6. Click the disable button.
