Production Ownership

Build a production container image for a .NET API

Builds a small, immutable, non-root .NET runtime image with controlled inputs, external configuration, graceful lifecycle behavior, and a practical patching strategy.

Container configuration, secrets, and environment promotion

Keeps images environment-neutral while handling configuration precedence, secret delivery, rotation, and startup validation safely.

Container CPU and memory limits with the .NET runtime

Connects orchestrator requests and limits to .NET GC, thread-pool behavior, throttling, OOM termination, and capacity planning.

Container filesystems, volumes, state, and logging

Separates ephemeral instance files from durable data and sends logs, uploads, caches, and diagnostics to storage with explicit lifecycle ownership.

Container image tags, digests, registries, and patching

Uses immutable image identity, controlled promotion, registry security, and deliberate base-image rebuilding instead of mutable latest tags.

Container networking, ports, DNS, and service discovery

Explains bind addresses, published ports, internal DNS, service identity, and why localhost changes meaning across container boundaries.

Behavioral & Real Project Scenarios

Practical stories for engineering judgment, ownership, collaboration, and production maturity.

A behavioral interview track built around real engineering scenarios: project ownership, vague requirements, trade-offs, code review, mentoring, risk communication, production bugs, incidents, estimates, learning, and process improvement.
