SpringBoot应用部署 - 使用Docker Compose对容器编排管理
如果docker容器是相互依赖的（比如SpringBoot容器依赖另外一个MySQL的数据库容器），那就需要对容器进行编排。本文主要介绍基于Docker Compose的简单容器化编排SpringBoot应用。
Docker Compose编排管理
本例子主要介绍基于SpringBoot + MySQL的应用基于Docker Compose的编排。
SpringBoot应用准备
主要在如下文章的基础上，基于Docker Compose编排部署。
- SpringBoot集成MySQL - 基于JPA的封装
- 在实际开发中，最为常见的是基于数据库的CRUD封装等，比如SpringBoot集成MySQL数据库，常用的方式有JPA和MyBatis； 本文主要介绍基于JPA方式的基础封装思路。
DockerCompose编排
DockerCompose编排配置如下
- 整体的文件结构
PS: 注意红色的字
- Docker Compose 配置文件
PS：参数可以设置成环境变量注入进来
version: "3.1"
services:
db-mysql:
image: mysql:8.0.28
