End-to-End DevSecOps Pipeline with Jenkins, Snyk & Trivy

In the modern world of software development, executing tasks promptly and securely is equally essential. While DevOps is automating and speeding up the processes of software delivery, integrating security checks within the development lifecycle is giving rise to DevSecOps.

In contemporary software engineering, security checks cannot be kept as a gatekeeping mechanism for the last step. Instead, modern engineering teams integrate security checks within the CI/CD pipeline—something made possible by technologies such as Jenkins, Snyk, and Trivy.

Understanding how to build a practical DevSecOps pipeline is an integral part of learning if you plan to take up a DevOps course in Bangalore. In this blog post, we will explain how Indian learners of DevOps, where advanced content of such workflows is still absent, can fill the gaps by covering the architecture, tools, and stages from source to production of an end-to-end DevSecOps workflow.

Understanding is Significance of DevSecOps in 2025

An emphasis on accelerated delivery, automation, and infrastructure-as-code defines traditional DevOps. While beneficial, these elements can lead to unaddressed security vulnerabilities, stale dependencies, or improperly configured containers.

DevSecOps resolves these concerns by 'shifting left'—integrating security measures at every stage of the development process instead of waiting until after deployment. This means that security is not just a concern for the operations team after the code is written, but it is integrated into the development process from the very beginning. Given the increase in cyberattacks and tighter compliance regulations, DevSecOps has transitioned from a 'nice-to-have' to a 'must-have.'

An efficient DevSecOps pipeline:

• Identifies and mitigates risks during the development stage

• Performs scans on both application source code and container images

• Maintains its enforcement of compliance while improving delivery speed

• Fosters better collaboration across development, operations, and security teams

Key Tools in the DevSecOps Pipeline

To implement a proper DevSecOps pipeline, it is necessary to select the right combination of automation tools. Here's a brief outline of some primary elements that we will be covering:

Jenkins

Jenkins is the linchpin of the CI/CD pipeline. It manages and automates the entire cycle from code retrieval, building, and testing to deployment. Both Snyk and Trivy can be integrated into Jenkins through plugins and command-line interface hooks, making them easy to apply.

Snyk

Snyk focuses on scanning the dependencies of an application. It scans for known vulnerabilities (CVEs) in open-source libraries for Java, Python, Node.js, and other languages and provides suggestions for remedial actions.

Trivy

Trivy is an open-source and straightforward container scanner. It can check Docker images for vulnerabilities, licenses, and misconfigurations. While other enterprise tools are burdensome and slow, Trivy is designed to be fast and easy to use, making it ideal for many Indian startups and for learning labs.

The DevSecOps Pipeline: Stage-by-Stage Breakdown

Now, let's take a look at how a DevSecOps pipeline functions, step by step. This approach is standard practice in many enterprises and is starting to make headway in the best DevOps courses in Bangalore.

1. Commit Source Code

A developer will push new code to a Git repository, such as GitHub, GitLab, or Bitbucket. Jenkins is set up to trigger pipelines automatically on every push to the main or develop branches.

2. Building the Software and Conducting a Snyk Dependency Scan: A Detailed Process

When Jenkins picks up the newly committed changes, it:

Retrieves the latest code.

Installs libraries and other dependencies using npm, Maven, or pip.

Runs Snyk to scan for vulnerabilities in dependencies and third-party libraries.

Snyk integrates seamlessly within the build process and will fail the pipeline if critical vulnerabilities are found. Feedback is instantaneous to the developers. They don't have to wait for code reviews to learn that insecure packages have been used.

This practice of shifting left security saves time and costs.

3. Static Code Analysis (Optional, But Recommended)

Integrating SonarQube at this stage may be used for general code quality, linting, and maintainability checks. While not explicitly security-oriented, these measures improve the maintainability of the code and expose illogical features that may be present.

4. Unit Tests and Coverage

Unit tests verify that the application logic is implemented correctly and Jenkins is accurately reporting a pass/fail and coverage percentage for TDD-enabled coding, including the necessary metrics to ensure test-driven development is followed.

Security Note: High coverage is often linked to lower security risks. This is usually the case since well-tested code has a much higher chance of being free from exploitable bugs.

5. Containerization and Image Scanning with Trivy

After the application has completed all tests, Jenkins proceeds to create a Docker image from the application using a specified Dockerfile.

Before the image is deployed, Trivy scans for:

Vulnerabilities at the operating system (OS) level.

CVE applications at a higher level.

Application-level hardcoded secrets or misconfigurations.

Should any critical issues be flagged, Jenkins is configured to stop the pipeline and notify the DevOps/security personnel.

The primary advantages of Trivy rest on its speed, resource efficiency, and ease of implementation within Jenkins pipelines. This is a notable benefit for learners attempting to model real-life projects during the DevOps course in Bangalore.

6. Deployment into Staging Environment

Provided the image has passed all the checks from Trivy, it is pushed to a Docker registry (Docker Hub, ECR, etc.), from where it is subsequently deployed into Kubernetes or a cloud-native staging environment through Helm or kubectl.

This way, the app is subjected to further testing in a production-like environment.

7. Integration Testing and Compliance Validation

While optional, this stage includes additional value through API security policies (Open Policy Agent) or even compliance tools such as OWASP ZAP.

There are a variety of strict security protocols that can be applied, including but not limited to:

Privileged access is restricted through role-based policies.

Secrets are maintained with HashiCorp Vault.

Defined network policies in the scope of Kubernetes.

8. Deployment to Production

As Jenkins completes all the necessary actions, it performs either a blue-green or rolling deployment to production. It is collecting logs and metrics and monitoring in real-time using Prometheus and Grafana.

Auditing tools maintain a detailed log for every action within the pipeline, such as who performed a particular action, ensuring compliance, and maintaining audit compliance.

What Makes Indian Learners Deficient in DevSecOps Skills

Despite the rise of DevSecOps, there are prominent gaps in the Indian education landscape focused on DevOps:

Absence of Security Components: Most curricula stop at CI/CD automation, completely ignoring SNYK and Trivy, which are SAST/DAST tools.

Absence of Mitigation Instruction: Learners can identify vulnerabilities, but there is no instruction on how to resolve those issues.

Basic Kubernetes Security: Overlooked are encryption for secrets, network segmentation, and role-based access control.

Absence of Real Pipelines: Students are taught little to no comprehensive security pipelines.

The Bangalore gap outlined can be effectively addressed with a comprehensive container security course incorporating writing pipelines, security tooling, and devices covered in structured frameworks.
