Docker-部署docker-compose以及管理服务

部署docker-compose以及管理服务

---

前言

Docker 是一个开源的容器化平台，可以帮助我们快速构建、打包和运行应用程序。而 Docker Compose 则是用于管理多个容器应用的工具，可以轻松定义和管理多个容器之间的关系。

一、docker-compose是什么？

1、介绍

Docker Compose是一个用来定义和运行复杂应用的Docker工具。Compose 通过一个配置文件来管理多个Docker容器，在配置文件中，所有的容器通过services来定义，然后使用docker-compose脚本来启动，停止和重启应用，和应用中的服务以及所有依赖服务的容器，非常适合组合使用多个容器进行开发的场景

2、 功能

Docker Compose功能点：

• 提供工具用于定义和运行多个docker容器应用;
• 使用yaml文件来配置应用服务(docker-compse.yml);
• 可以通过一个简单的命令docker-compse up可以按照依赖关系启动所有服务;
• 可以通过一个简单的命令docker-compose down停止所有服务;
• 当一个服务需要的时候，可以很简单地通过–scale进行扩容;

二、安装docker-compose

compose安装方式有三种，以下来介绍。

1.yum直接安装

#安装docker-compose，如果没有python3会安装python3yum install -y docker-compose

2.二进制安装

从github上下载docker-compose二进制文件安装

3.pip安装

pip install docker-compose

三、docker-compose部署服务

1.编写docker-compose.yml文件

version: '3.5'

以上是docker-compose在实际项目中的使用配置，大家可以参考。
