Docker

Dockerfile

There are two variants of Dockerfile used for both backend and frontend:

1. Production (Dockerfile)
   • Installs only packages required in production (no devDependencies)
   • Copies only required files to the image
   • Tries to be minimal so the image would be fast and small
2. Development (dev.Dockerfile)
   • Installs all packages from package.json
   • Copies all files from backend to the image (not counting .dockerignored files)
   • Has multiple stages (dev and api-tests)
     • Learn more about multi-stage Dockerfiles: https://docs.docker.com/build/building/multi-stage/
   • Includes everything that is required / helps with development and testing
