docker安装milvus

docker-compose 安装 milvus

总共安装4个服务

• etcd : 存储解析milvus的数据
• minio : 文件服务器
• milvus : 主要的向量数据库
• attu : milvus的可视化界面工具

docker-compose 安装

其他3个服务不同版本差距不大，

但是不同版本的milvus差距很大

我的milvus版本为: milvusdb/milvus:v2.3.12

version: '3.5'

      retries: 3
    ports:
      - "19530:19530"
      - "9091:9091"
    depends_on:
      - "etcd"
      - "minio"
  
  attu:
    container_name: attu
    image: zilliz/attu:v2.3.9
    environment: 
      MILVUS_URL: milvus-standalone:19530
    ports:

    depends_on:

如果本机有网络，那就直接在本机执行 docker-compose up -d 安装即可;

如果本机没网络，那就去别的有网络的地方下载docker镜像，然后转移到本机；

如果找不到镜像，可以去以下几个网站找一下

https://docker.1ms.run
https://docker.xuanyuan.me
https://dislabaiot.xyz
https://docker.sunzishaokao.com
https://hub.rat.dev
https://doublezonline.cloud
https://dislabaiot.xyz
https://xdark.top

启动成功应该显示如下

启动命令：docker-compose up -d

此时启动，milvus-standalone 服务可能跑不起来，或者跑十几秒就挂了，因为他连不上minio文件服务器，此时我们需要打开浏览器，连接 服务器ip:9001，登录minio管理界面，在bucket列表，生成一个a-bucket的桶，并设置为public;

再 docker restart milvus-standalone

应该成功了，查看容器允许信息；

docker ps

可视化界面

访问attu: 浏览器输入 ip:3000

踩坑记录

端口占用

运行的时候，发现端口被占用，导致起不动，记得用命令：netstat -ntulp|grep 你的端口 来检测是否被占用端口；

必须要开放出去的端口 : 9001-minio的端口，需要我们启动后设置桶信息；3000-attu端口，可视化界面；19530-milvus端口，核心服务；

milvus访问minio

重点：

当前docker-compose,指定的这四个容器是在同一网络下，

networks:
  default:
    name: milvus

因此，下面这行的端口，要用容器本身的端口9000，不能用映射出来的9002

 MINIO_ADDRESS: minio:9000

提示：如果你的网络模式是host,或者bridge,这里访问的信息就要改成:

MINIO_ADDRESS: 你的宿主机IP:你本机映射的端口
