container-plugin

Container build and debugging. Builds Docker images, analyzes build failures, inspects layers, and troubleshoots container issues. Use for Docker/container operations.

Container development with Docker, Dockerfiles, 12-factor principles, multi-stage builds, and Skaffold workflows. Enforces MANDATORY non-root users, minimal Alpine/slim base images, and security hardening. Covers containerization, orchestration, and secure image construction. Use when user mentions Docker, Dockerfile, containers, docker-compose, multi-stage builds, container images, container security, or 12-factor app principles.

Generate professional handoff messages for deployed resources and services with all necessary information for developer handoff.

Go-specific container optimization patterns including static binary compilation, scratch/distroless base images, CGO handling, and systematic optimization journey from 846MB to 2.5MB (99.7% reduction). Covers ldflags, trimpath, and build flag optimizations specific to Go applications. Use when working with Go containers, Dockerfiles for Go apps, or optimizing Go image sizes.

Node.js-specific container optimization patterns including Alpine variants, multi-stage builds, node_modules caching, production dependency separation, and optimization from ~900MB to ~50-100MB. Covers npm/yarn/pnpm patterns, BuildKit cache mounts, and non-root user configuration. Use when working with Node.js containers, Dockerfiles for Node apps, or optimizing Node image sizes.

Python-specific container optimization patterns including slim base images (NOT Alpine), virtual environment handling, multi-stage builds with pip/poetry/uv, and optimization from ~1GB to ~80-120MB. Covers musl libc issues, wheel building, and Python-specific dependency management patterns. Use when working with Python containers, Dockerfiles for Python apps, or optimizing Python image sizes.

Fast iterative development with Skaffold file sync - copy changed files to running containers without rebuilding images. Use when optimizing the development loop, configuring sync rules, or when the user mentions file sync, hot reload, live reload, or fast iteration.

OrbStack-optimized Skaffold workflows for local Kubernetes development without port-forward. Use when configuring Skaffold with OrbStack, accessing services via LoadBalancer or Ingress, or when the user mentions OrbStack, k8s.orb.local, service access, or eliminating port-forward.

Container image validation with Skaffold test and verify stages. Covers container-structure-tests for image hygiene, custom tests for security scanning, and post-deployment verification. Use when configuring pre-deploy tests, security scans, or integration tests in Skaffold pipelines.
