Designing a Secure Jenkins CI/CD Pipeline

A production pipeline must do three things well:

• Be deterministic

• Be secure

• Be debuggable

My Jenkins pipeline is structured into clear, auditable stages:

• Checkout

• Build

• Security scan

• Push images

• Infrastructure provisioning

• Deployment

• Validation

Each stage can:

• Fail independently

• Block insecure artifacts

• Produce meaningful logs

Security is not a final step; it’s embedded into the pipeline flow.
