Do you know the configs/settings for microservices that are pulled through Docker environment variables?

Configurations and settings of microservices that are passed through environment variables in Docker are usually called environment variables. In the context of microservices and Docker, these can be:

• Environment variables — a standard way to pass configuration to containers.
• Config maps and Secrets — used in Kubernetes for managing configuration and secret data.

In Docker Compose files, environment variables are set via environment, and in Dockerfile — via ENV.

Example in Docker Compose:

services:
  app:
    image: myapp
    environment:
      - DB_HOST=database
      - DB_PORT=5432

Thus, configs pulled through environment variables are simply called environment variables.
