Program narrative
We pair Dockerfile hardening with registry scanning and runtime profiling. You will rehearse hand-offs to platform teams using checklists grounded in local regulatory expectations.
What is included
- · Multi-stage builds with deterministic tags
- · Read-only root filesystem patterns
- · cgroup and memory profiling exercises
- · SBOM generation in CI
- · Health checks that reflect real readiness
- · Graceful shutdown drills
- · Language-specific base image trade-offs
Outcomes you can show
- Publish a hardened service template with scanning gates
- Produce a runtime budget other teams can trust
- Deliver a concise hand-off brief for cluster owners

FAQ
Experience notes
“We ran the shutdown drill in our team retro the next sprint. Solid framework.”
“Mentor notes on our Dockerfile layers cut image size by a third without breaking caches.”
“Short, punchy critique of our health checks—exactly what we needed before go-live.”
