How to build multiple application containers with Docker?

Creating multiple application containers can be achieved in the following ways:

1. Creating an image using Docker

docker build -t app1-image /path/to/app1
docker build -t app2-image /path/to/app2

1. YAML file for Docker Compose
2. start the Docker containers

version: '3'
services:
  app1:
    build:
      context: ./path/to/app1
      dockerfile: Dockerfile
    # 其他配置参数

  app2:
    build:
      context: ./path/to/app2
      dockerfile: Dockerfile
    # 其他配置参数

Then run:

docker-compose up

1. Some build platforms like Jenkins and Travis CI have integrated Docker build capabilities, allowing users to build multiple application containers by configuring build tasks. These platforms typically offer a visual interface and a variety of configuration options, enabling more flexibility in building and managing multiple containers.

Regardless of the method used, it is necessary to define a separate Dockerfile or configuration for each application, and specify different context paths or build parameters during construction to differentiate between different application containers.
