docker-runtime-verification

name	docker-runtime-verification
description	Verify this repository's Docker image build and runtime behavior with deterministic checks for standalone Next.js deployments. Use when changing Dockerfile/.dockerignore, Next/i18n config, startup scripts, or debugging Kubernetes startup and Internal Server Error issues.

Docker runtime verification

Quick start

yarn build
bash .github/skills/docker-runtime-verification/scripts/verify-docker-runtime.sh

What this verifies

• Docker image builds from current repo state.
• Container starts and serves on mapped port.
• /app/next-i18next.config.js exists in runtime image.
• Readiness endpoint returns 200: /fyllut-ettersending/api/internal/isready.
• Logs do not contain known failure: next-i18next was unable to find a user config.
• /fyllut-ettersending/lospost responds with 200.

Repo-specific checks

• Confirms .dockerignore allows next-i18next.config.js.
• Confirms Dockerfile copies next-i18next.config.js into /app.

Typical fixes when it fails

• Add missing allowlist entry in .dockerignore.
• Add missing COPY for runtime config in Dockerfile.
• Rebuild app (yarn build) so .next/standalone is fresh.
• Inspect emitted container logs printed by the script on failure.
