Docker Compose milvus 2.2.8 升级到2.3.15 版本

一、官方升级方案

官方升级文档：https://milvus.io/docs/v2.3.x/upgrade_milvus_standalone-docker.md

根据官方文档上写的，升级主要是以下几点：

1、在milvus v2.2.5版本以后，MinIO 的版本升级到了 RELEASE.2023-03-20T20-16-18Z ，如果使用的版本小于这个，需要迁移minio数据，我们使用的2.2.8版本不需要

2、升级Milvus版本，修改docker-compose.yaml ，如下：

standalone:

container_name: milvus-standalone

image: milvusdb/milvus:v2.3.15

3、 迁移etcd中的元数据

二、具体操作思路

由于我们使用的 milvus 2.2.8和milvus 2.3.15版本的minio 和etcd组件的版本都是一样的，只是一些其他配置略微不通，所以比较简单，如下：

1、停止原理的所有组件服务，备份老版本docker-compose.yaml 文件

# cd /opt/Milvus

# docker-compose stop

# docker ps

# cp docker-compose.yaml docker-compose.yaml.bak

2、下载milvus 2.3.15 版本的docker-compose.yaml ,将其放到老的milvus目录

# cd /opt/Milvus

# wget https://github.com/milvus-io/milvus/releases/download/v3.15/milvus-standalone-docker-compose.yml -O docker-compose.yml

# cat docker-compose.yaml (attu 服务是我自己添加)

3、启动milvus所有组件服务，查看各组件状态

# cd /opt/Milvus

# docker-compose up -d

# docker ps
