Infrastructure / Container Security Market: Container Security Checklist for SREs
A technical how-to and checklist for site reliability engineers (SREs) covering container security best practices. The article recommends using minimal multi-stage base images to reduce attack surface, scanning container images (example with Trivy in a GitHub Actions workflow), running containers as non-root with Kubernetes securityContext settings, applying network policies and pod security standards, managing secrets via external vaults (e.g., HashiCorp Vault), enforcing resource limits, and automating weekly audits (using kubectl, skopeo, jq). The author is Dr. Samson Tanimawo, Founder & CEO of Nova AI Ops.
Practical, actionable container security guidance relevant to engineering and operations teams running containerized infrastructure; useful but not industry-shifting.
Key Takeaways & Evidence Grounding
- Article provides a container security checklist aimed at SREs including image scanning, non-root containers, network policies, secrets management, resource limits, and pod security standards.
- Recommends image scanning in CI (example uses aquasecurity/trivy-action in a GitHub Actions workflow) and failing builds on HIGH/CRITICAL vulnerabilities.
- Advises using multi-stage builds and slim base images to minimize image size and attack surface, and running processes as non-root (Kubernetes securityContext examples provided).
- Shows Kubernetes NetworkPolicy examples for default deny and service-specific allow rules, and recommends injecting secrets from an external Vault (vault.hashicorp.com annotations).
- Includes a weekly audit automation script that checks image creation dates (skopeo), privileged containers, containers running as root, and missing resource limits; findings become tickets.
