PermalinkDeveloper Writes Code & Raises PR:
Developer
: Writes new code or modifies existing code in a feature branch.
Code Review
: The developer raises a Pull Request (PR) to merge their changes into a target branch (e.g., develop or main). The PR is reviewed by peers for code quality, adherence to coding standards, and potential issues.
PermalinkMerge & Trigger Pipeline:
Merge PR
: Once the PR is approved, it gets merged into the target branch. This merge action automatically triggers the CI/CD pipeline configured for the project.
PermalinkPipeline Stages:
Description: Set up the build environment with necessary tools.
PermalinkActions:
▪ Use a script or configuration file (e.g., Ansible, Chef, Puppet) to install tools like Java JDK, Node.js, Docker, Maven, etc.
Ensure version consistency across different environments.
PermalinkInstall Dependencies:
Description: Download and install all project dependencies.
PermalinkActions:
Use package managers such as npm for Node.js, pip for Python, or Maven for Java to install required libraries and frameworks.
Create a clean environment for each build to ensure no leftover dependencies affect the process.
PermalinkRun Test Cases:
Description: Execute automated tests to validate the code.
Unit Tests: Check individual components for correctness using frameworks like JUnit, NUnit, or Mocha.
Integration Tests: Validate interactions between components.
Code Coverage: Measure how much of the codebase is covered by tests.
PermalinkRun SonarQube Analysis:
Description: Perform static code analysis for quality and security.
PermalinkActions:
Use SonarQube to scan the code for code smells, bugs, and vulnerabilities.
Generate detailed reports and ensure the code meets defined quality gates.
PermalinkRun Trivy File System Scan:
Description: Scan the file system for vulnerabilities and compliance issues.
PermalinkActions:
Use Trivy to scan for known vulnerabilities in OS packages, application dependencies, and configuration files.
Review and address any identified issues before proceeding.
PermalinkBuild App:
Description: Compile the source code into a deployable artifact.
PermalinkActions:
▪ Use build tools like Maven, Gradle, or npm to compile the code.
▪ Generate artifacts such as JAR, WAR, or binary files.
PermalinkPublish Artifacts to Nexus:
Description: Store the built artifacts in a repository manager.
PermalinkActions:
▪ Upload artifacts to Nexus Repository Manager.
▪ Version control the artifacts for traceability and rollback capabilities.
PermalinkBuild Docker Image:
Description: Package the application into a Docker image.
PermalinkActions:
▪ Use a Dockerfile to define the environment and dependencies.
▪ Build the Docker image and tag it with appropriate version numbers.
PermalinkScan Docker Image:
Description: Ensure the Docker image is secure and free of vulnerabilities.
PermalinkActions:
▪ Use tools like Trivy, Clair, or Aqua Security to scan the Docker image.
▪ Address any vulnerabilities before proceeding.
PermalinkDeploy to Kubernetes:
Description: Deploy the Docker image to a Kubernetes cluster.
PermalinkActions:
▪ Use Kubernetes manifests or Helm charts to define the deployment.
▪ Deploy the application to the cluster, managing pods, services, and ingress rules.
PermalinkFunctional Testing:
Description: Validate the application’s functionality in the deployed environment.
PermalinkActions:
▪ Use tools like Selenium, Postman, or Cucumber to run automated functional tests.
▪ Ensure the application meets all functional requirements and behaves as expected.
PermalinkPenetration Testing:
Description: Perform security testing to identify potential vulnerabilities.
PermalinkActions:
▪ Use tools like OWASP ZAP, Burp Suite, or Nessus to conduct penetration testing.
▪ Identify and mitigate any security vulnerabilities found.
