description: Generates Dockerfile in project root for application containerization and deployment with conditional component library and Datadog integration.

Docker Skill

Purpose

Generate Dockerfile in the project root directory for containerization and deployment.

Output

Create the file: Dockerfile (in project root)

Template

See: examples.md for the exact configuration template with placeholders.

Conditional Logic

Component Library Authentication

Check parameter: include_component_library

If "yes": Replace {{COMPONENT_LIBRARY_AUTH}} with:

dockerfile
RUN --mount=type=secret,id=vite_access_token \
export VITE_ACCESS_TOKEN=$(cat /run/secrets/vite_access_token) && \
echo "@RoyalAholdDelhaize:registry=https://npm.pkg.github.com" > .npmrc && \
echo "//npm.pkg.github.com/:_authToken=${VITE_ACCESS_TOKEN}" >> .npmrc

If "no": Replace {{COMPONENT_LIBRARY_AUTH}} with empty string (remove lines)

Note: RUN npm install is always present after the placeholder, regardless of component library choice.

Key Features

  • •Base image: Ubuntu Node.js 22 LTS from Azure Container Registry
  • •Quality checks: Runs lint, stylelint, and unit tests during build
  • •Nginx: Installs and configures nginx for serving static files
  • •Security: Runs as non-root user (nodejs_svc)
  • •Port: Exposes 8080
  • •Optimization: Cleans apt cache to reduce image size

Notes

  • •All configuration values are production-ready defaults
  • •Build fails if quality checks don't pass
  • •Component library authentication uses Docker secrets for security
  • •References nginx configuration files created by nginx skills
