High level overview of a typical CI/CD Pipeline
Overview of the Application Infrastructure
First of the 2 services will be the test_service in this application architecture that will be responsible for taking requests to add new users and send it to the test_app micro service in the ecosystem.
The test_app micro service is the 2nd micro service in the ecosystem that will take the user add request from test_service and insert the user into the MySQL database and then send a confirmation message to the client.
You will get a overview of how the test_service is setup in Git as well as a quick walk through in the source code. You will also get a view of the Config.yml file which is the configuration file for Circle CI.
You will see how the docker-compose is setup for this service and a quick overview of the integration test client application.

You will see a local execution of the Integration test and then we will see how that test is run in the Circle CI pipeline.
A quick walk through of similar integration test setupin the test_app serviceand a summary.
In a development environment that implements a robust CI/CD pipeline, it would be nice if integration tests could be performed in the CI pipeline as part of the regular PR approval process before deploying to the environment. This will be a quick crash course to give you a hands on approach to make that happen. You will learn to develop and execute integration tests in the CI pipeline using docker-compose. For this course we will be using Circle CI as the CI tool of choice. We will use IntelliJ for the IDE and use a simple Java Microservice to demonstrate the pipeline. You will get high level exposure to use and configure the CI pipeline. We will touch on the config.yml configuration file which is the backbone of Circle CI. You will also get a brief exposure to using a RESTful Feign Client and Liquibase schema migration tool to enforce database schema. For this course you will need to download and install Docker desktop and open a Circle CI account (its free). You will also need to open a free GitHub account. At the end of this course you will be able to download the code files so that you can practice this yourself.
