Variants

This repository builds 3 variants of images: a local image, a production container image, and a production serverless image.

Local

The local image variant is used to run node in an isolated development environment on your local machine.

• CMD is set to node app.js to run a development server.
• PORT is set to 9000 to align with Nullstone conventions to quickly attach nginx sidecar (example coming soon)
• ENTRYPOINT is set to a custom entrypoint script that does the following:
  • Run yarn install - Allows developer to run docker compose restart app to make changes to dependencies
  • If POSTGRES_URL is specified, set DB_ADAPTER=postgresql, DATABASE_URL=$POSTGRES_URL
  • If MYSQL_URL is specified, set DB_ADAPTER=mysql, DATABASE_URL=$MYSQL_URL

Production

The production image variant uses node to run a node app in production mode.

• PORT is set to 80
• ENTRYPOINT is set to a custom entrypoint script that does the following:
  • If POSTGRES_URL is specified, set DB_ADAPTER=postgresql, DATABASE_URL=$POSTGRES_URL
  • If MYSQL_URL is specified, set DB_ADAPTER=mysql, DATABASE_URL=$MYSQL_URL
