Devsecops In Practice With Vmware Tanzu Pdf -

Let us walk through a practical DevSecOps workflow using VMware Tanzu.

Tanzu integrates natively with GitOps tools (Flux, Argo CD) and CI runners (Jenkins, GitLab CI, GitHub Actions).

Typical Pipeline (Tanzu CLI + GitHub Actions): devsecops in practice with vmware tanzu pdf

# .github/workflows/devsecops-tanzu.yml
steps:
  - name: Checkout code
  - name: Run SAST (SonarQube)
  - name: Build image with Tanzu Build Service
  - name: Scan image (Grype, Trivy, or Snyk)
  - name: Sign image with Cosign
  - name: Deploy to Tanzu cluster via kapp

Security gate: Pipeline fails if critical CVE is found or if signature verification fails.

Teams using ArgoCD or Flux often store secrets as base64 encoded YAML (bad). Tanzu Solution: Use Secrets Store CSI Driver integrated with HashiCorp Vault. The PDF provides YAML snippets showing how to mount a secret without it ever touching the etcd database. Let us walk through a practical DevSecOps workflow

Kubernetes admission controllers are the police force of your cluster. The PDF details how to implement Rego policies via Tanzu’s integration with Open Policy Agent (OPA) Gatekeeper.

Example Policy from the PDF: Reject any Pod that does not have a securityContext limiting allowPrivilegeEscalation: false. Security gate: Pipeline fails if critical CVE is

Without this, a developer could inadvertently run a container as root. With Tanzu, the Cluster API enforces this policy at kubectl apply time, rejecting the deployment instantly with a clear error message.

A typical DevSecOps pipeline using VMware Tanzu includes the following stages:

| Stage | Tanzu Component | Security Action | |--------|----------------|------------------| | Code & Commit | Git (any) + Tanzu CLI | SAST (e.g., Grype, Snyk) | | Image Build | Tanzu Build Service (kpack + Buildpacks) | Base OS patch management; SBOM generation | | Image Registry | Harbor (integrated with Tanzu) | Vulnerability scanning; image signing (Cosign/Notary) | | Supply Chain | Tanzu Supply Chain / Cartographer | Policy validation (OPA/Gatekeeper) | | Deployment | Tanzu Kubernetes Grid | Network policies; Pod Security Standards | | Runtime | Tanzu Observability + Tanzu Security | Runtime threat detection; audit logging |
