DevOps Corporate Workflow

DevOps Corporate Workflow

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.

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.

Description: Set up the build environment with necessary tools.

▪ 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.

Description: Download and install all project dependencies.

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.

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.

Description: Perform static code analysis for quality and security.

Use SonarQube to scan the code for code smells, bugs, and vulnerabilities.

Generate detailed reports and ensure the code meets defined quality gates.

Description: Scan the file system for vulnerabilities and compliance issues.

Use Trivy to scan for known vulnerabilities in OS packages, application dependencies, and configuration files.

Review and address any identified issues before proceeding.

Description: Compile the source code into a deployable artifact.

▪ Use build tools like Maven, Gradle, or npm to compile the code.

▪ Generate artifacts such as JAR, WAR, or binary files.

Description: Store the built artifacts in a repository manager.

▪ Upload artifacts to Nexus Repository Manager.

▪ Version control the artifacts for traceability and rollback capabilities.

Description: Package the application into a Docker image.

▪ Use a Dockerfile to define the environment and dependencies.

▪ Build the Docker image and tag it with appropriate version numbers.

Description: Ensure the Docker image is secure and free of vulnerabilities.

▪ Use tools like Trivy, Clair, or Aqua Security to scan the Docker image.

▪ Address any vulnerabilities before proceeding.

Description: Deploy the Docker image to a Kubernetes cluster.

▪ Use Kubernetes manifests or Helm charts to define the deployment.

▪ Deploy the application to the cluster, managing pods, services, and ingress rules.

Description: Validate the application’s functionality in the deployed environment.

▪ Use tools like Selenium, Postman, or Cucumber to run automated functional tests.

▪ Ensure the application meets all functional requirements and behaves as expected.

Description: Perform security testing to identify potential vulnerabilities.

▪ Use tools like OWASP ZAP, Burp Suite, or Nessus to conduct penetration testing.

▪ Identify and mitigate any security vulnerabilities found.
