Docker 和 Docker Compose 之间的区别
docker 和 docker compose 都可以用来运行 Docker 容器。 这两个 Docker 结构具有可比性，但仅限于此。
本文将讨论 docker 和 docker compose 之间的主要区别。
Docker 和 Docker Compose 之间的区别
docker 和 docker compose 之间的关键区别在于 docker 仅依赖命令行 (CLI)，而 docker compose 从 YAML 文件接收配置信息。
第二个关键区别是 docker-compose 可以配置和操作多个容器，而 docker 只能同时启动一个容器。
运行 Docker CLI
Docker 引擎通过 docker CLI 管理各个容器。 要联系 Docker 守护程序 API，请使用客户端命令行。
示例代码：
docker run -d --rm --name=my-website --cpus=1.5 --memory=1048m -p 80:80 -v /usr/share/nginx/html/ nginx:latest
同时，我们可以使用 docker-compose CLI 来管理多容器应用程序。 它还将您将在 docker run CLI 上输入的许多选项移动到 docker-compose.yml 文件中，以便于重用。
它作为 docker 使用的相同 Docker API 之上的暂存区，允许我们利用 docker 命令和大量 shell 脚本来完成 docker compose 可以完成的任何事情。
YAML 文件：
version: '3.9'
services:
nginx-test-service:
container_name: sample-website
image: nginx:latest
cpus: 1.5
mem_limit: 1024m
ports:
- "80:80"
volumes:
/usr/share/nginx/html
示例代码:
$ docker-compose up -d --rm
