Use when containerizing an application from scratch or generating Dockerfile and Compose configurations for a new project. Prevents insecure defaults by enforcing non-root users, multi-stage builds, health checks, and proper .dockerignore from the start.…
Use when reviewing a Dockerfile or Compose file before merging, deploying, or auditing container security posture. Prevents shipping containers that run as root, lack health checks, expose secrets in layers, or use mutable tags like latest. Covers Dockerfile…
Use when designing Docker container architecture or explaining how Docker Engine components interact. Prevents misconceptions about container isolation, image layering, and the relationship between daemon, containerd, and runc. Covers Docker Engine…
Use when configuring Docker networks, debugging container connectivity, or setting up service discovery between containers. Prevents using the default bridge network in production, which lacks DNS resolution and automatic service discovery. Covers bridge,…
Use when hardening containers, scanning images for vulnerabilities, or implementing least-privilege Docker deployments. Prevents running containers as root, exposing secrets in image layers, and skipping vulnerability scanning before production deployment.…
Use when debugging Docker build failures or unexpected cache behavior. Prevents wasted hours from misunderstanding COPY context paths, cache invalidation rules, and BuildKit mount syntax. Covers build errors, COPY/ADD not found, context too large, cache…
Use when docker compose up fails, services refuse to start, or dependency health checks time out. Prevents cascading failures from unvalidated Compose files, incorrect depends_on conditions, and unescaped environment variable interpolation. Covers service…
Use when containers cannot reach each other, DNS resolution fails between services, or published ports are not accessible from the host. Prevents connectivity failures from using the default bridge network, which lacks automatic DNS resolution and proper…
Use when a running container crashes, exits unexpectedly, or behaves incorrectly at runtime. Prevents misdiagnosis of OOM kills, permission denied errors, and silent container exits by following the logs-exec-inspect-events workflow. Covers exit codes,…
Use when optimizing Docker build times or fixing unexpected cache invalidation. Prevents full rebuilds from incorrect instruction ordering and bloated images from missing .dockerignore entries. Covers layer caching rules, cache invalidation triggers,…
Use when setting up Docker CI/CD pipelines, pushing images to registries, or configuring multi-platform builds with GitHub Actions. Prevents broken workflows from incorrect docker/build-push-action usage, missing registry authentication, or misconfigured…
Use when setting up multi-environment Compose workflows or merging override files. Prevents environment variable shadowing from incorrect precedence and broken extends from circular dependencies. Covers profiles, extends, include, compose.override.yaml, .env…
Use when formatting Docker CLI output with --format flags or extracting specific fields from docker inspect. Prevents broken template syntax from missing braces, incorrect field paths, and unquoted json calls. Covers Go template syntax, {{ .Field }}, json,…
Use when hardening Dockerfiles for production deployment or choosing base images. Prevents containers running as root, missing HEALTHCHECK definitions, and zombie processes from shell-form ENTRYPOINT. Covers base image selection, USER, HEALTHCHECK, exec form,…
Use when persisting container data, mounting host directories, or configuring database storage volumes. Prevents data loss from anonymous volumes on container removal and silent mount failures with -v syntax. Covers named volumes, bind mounts, tmpfs, --mount…
Use when optimizing Dockerfile builds with cache mounts, mounting secrets during build, or writing multi-line RUN with heredoc syntax. Prevents baking credentials into image layers, cache-busting on every build due to missing --mount=type=cache, and using…
Use when running, inspecting, or managing Docker containers from the CLI. Prevents silent data loss from missing -v on rm, zombie containers from skipped stop commands, and incorrect docker run flag combinations. Covers docker run, exec, logs, inspect, stats,…
Use when building, tagging, pushing, or cleaning up Docker images. Prevents dangling image accumulation from missing prune commands and broken deployments from incorrect tag or push sequences. Covers docker buildx build, pull, push, tag, images, rmi, image…
Use when defining top-level networks, volumes, configs, or secrets in compose.yaml. Prevents misconfigured network drivers, orphaned volumes, and secrets mounted with wrong permissions. Covers networks, volumes, configs, secrets, IPAM, external resources,…
Use when writing compose.yaml service definitions, configuring service dependencies, or setting up health checks and resource limits. Prevents depends_on without condition: service_healthy, which starts dependent services before the upstream is actually…
Use when writing or reviewing Dockerfiles, choosing between CMD and ENTRYPOINT, or selecting COPY vs ADD. Prevents shell-form CMD that blocks signal propagation, ADD for local files where COPY suffices, and missing HEALTHCHECK in production images. Covers all…
Use when optimizing Docker image size, separating build-time and runtime dependencies, or creating minimal production images. Prevents shipping compilers, build tools, and source code in production images by failing to use COPY --from to extract only final…
