Compose 使用的三个步骤: (1) 使用 Dockerfile 定义应用程序的环境。 (2) 使用 docker-compose.yml 定义构成应用程序的服务,这样它们可以在隔离环境中一起运行。 (3) 执行 docker-compose up 命令来启动并运行整个应用程序。 docker-compose.yml 示例如下(配置参数参考下文): ...
运行docker compose up,Docker compose 命令启动并运行整个应用程序。也可docker-compose up使用 Compose 独立运行(docker-compose二进制) 2 docker-compose.yml 已有三个版本,建议使用version3。 2.1 核心概念 2.1.1 Services 一个service代表一个container,这个container可以从dockerhub的image来创建或从本地的Dockerfile...
