CodeCatalyst CI Workflows for Java-SpringBoot Application

This is a simple example of two Continuous Integration workflows created in CodeCatalyst for a Java & Spring-Boot based backend application. The application exposes one API to perform a sum between integers Calculation
The repository includes, inside the .codecatalyst/workloads folder, the definition of two CodeCatalyst workflows:
- build.yaml: the workflow builds the jar, performs a CodeGuru Security review, uploads it to CodeArtifact, builds the Docker images, uploads it to ECR
- test.yaml: the workflow perform unit and coverage tests on code

Usage

The purpose of this repository is to show how to create CI workflows on CodeCatalyst to perform actions for a SpringBoot Java based application

Getting Started / Prerequisites

The example project is built with Java 17 and Maven 3. Please be aware that you'll need those to run the project locally.
You'll need to create a CodeCatalyst space, a new Project with a new Code Repository
You'll need to connect the CodeCatalyst Space to an AWS Account selecting one or more IAM Roles. This AWS Account will be used to store Docker images (ECR) and Java Artifacts (CodeArtifact). The connection you created will be used to interact with the AWS Account Resources through proper IAM Roles.
- PLEASE NOTE: During the creation of the CodeCatalyst connection to the target AWS Account, you'll need to create a proper IAM Role that will be assumed by CodeCatalyst (or use an existing one). For this example we've used a IAM Role assigning to it the policy you can find in the file CodeCatalystRolePolicyExample.json. This IAM policy is very permissive so please don't use it for production purposes!!
For this particular example we're assuming:
- AWS Account ID: 123456789012
- CodeCatalyst Environment (targeting the account above) named "TestEnvironment" referencing the "CodeCatalystTestEnvironmentRole" IAM role created in account 123456789012

Creating ECR and CodeArtifact repositories

You'll need to create an ECR repository and a CodeArtifact repository and properly substitute values inside ./codecatalyst/workflows/build.yaml

Instructions to create ECR repository via CLI:

aws ecr create-repository \
--repository-name rest-calculator \
--region us-east-1

Instructions to create a CodeArtifact repository via CLI

# Creating a domain
aws codeartifact create-domain --domain artifact-store-demo --region us-east-1

# Creating repository 
aws codeartifact create-repository --domain artifact-store-demo --domain-owner 123456789012 --repository artifact-store-demo --description "My new repository" --region us-east-1

Replace values inside Build pipeline

The files ./codecatalyst/workflows/build.yaml contains a fake account ID (123456789012). Please replace it with your correct AWS Account ID

CI Workflows

The project contains two CodeCatalyst workflows:

Test Workflow (.codecatalyst/workloads/test.yaml)
Build & Release Workflow (.codecatalyst/workloads/build.yaml)

Test Workflow

The main goal of this workflow is to run unit and coverage tests. The workflow is triggered by Pull Requests. Proper Success Criterias are defined for unit and coverage tests and unit and coverage reports are autodiscovered and will be available for every run.

The application project is fully based on Maven 3, and, for that reason, we use Maven commands to run those test. More specifically we're using a single Maven Wrapper (https://github.com/apache/maven-wrapper) command mvn -ntp verify. For unit testing we leverage JUnit 5, and for coverage test we leverage Jacoco Code Coverage Library (https://github.com/jacoco/jacoco)

Build & Release Workflow

This workflow performs several steps, more specifically:

Listing files
Maven Cleaning
Performs a Code Security Review (the report that will be produced will be available for each run)
Building the jar & uploading it to CodeArtifact repository
Building the Docker image and uploading it to ECR
