How do we wrap microservices? In what? How to deploy the entire system with one command?

Microservices are usually wrapped in containers, most often Docker, to ensure isolation, reproducibility, and ease of deployment. Each microservice is packaged into its own Docker image with the necessary dependencies.

To manage the entire system of multiple microservices, orchestrators such as Docker Compose or Kubernetes are used. This allows all services to be started with a single command and their configuration to be managed centrally.

Example with Docker Compose:

version: '3'
services:
  service1:
    image: myservice1:latest
    ports:
      - "3000:3000"
  service2:
    image: myservice2:latest
    ports:
      - "3001:3001"

Starting the entire system with one command:

docker-compose up -d

Thus, microservices are wrapped in containers, and an orchestration tool is used for deployment, allowing services to be launched and scaled centrally.
