数据库	Milvus

官网：https://milvus.io/

仓库地址：https://github.com/milvus-io

中文文档：https://milvus.io/docs/zh/quickstart.md

二.安装

2.1 docker-compose 安装

milvus-standalone-docker-compose.yml

version: '3.5'

services:
  etcd:
    container_name: milvus-etcd
    image: quay.io/coreos/etcd:v3.5.16
    environment:
      - ETCD_AUTO_COMPACTION_MODE=revision
      - ETCD_AUTO_COMPACTION_RETENTION=1000
      - ETCD_QUOTA_BACKEND_BYTES=4294967296
      - ETCD_SNAPSHOT_COUNT=50000
    volumes:
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/etcd:/etcd
    command: etcd -advertise-client-urls=http://127.0.0.1:2379 -listen-client-urls http://0.0.0.0:2379 --data-dir /etcd
    healthcheck:
      test: ["CMD", "etcdctl", "endpoint", "health"]
      interval: 30s
      timeout: 20s
      retries: 3

  minio:
    container_name: milvus-minio
    image: minio/minio:RELEASE.2023-03-20T20-16-18Z
    environment:
      MINIO_ACCESS_KEY: minioadmin
      MINIO_SECRET_KEY: minioadmin
    ports:
      - "9001:9001"
      - "9000:9000"
    volumes:
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/minio:/minio_data
    command: minio server /minio_data --console-address ":9001"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3

  standalone:
    container_name: milvus-standalone
    image: milvusdb/milvus:v2.5.3
    command: ["milvus", "run", "standalone"]
    security_opt:
    - seccomp:unconfined
    environment:
      ETCD_ENDPOINTS: etcd:2379
      MINIO_ADDRESS: minio:9000
    volumes:
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/milvus:/var/lib/milvus
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9091/healthz"]
      interval: 30s
      start_period: 90s
      timeout: 20s
      retries: 3
    ports:
      - "19530:19530"
      - "9091:9091"
    depends_on:
      - "etcd"
      - "minio"

networks:
  default:
    name: milvus

yml 文件中修改，不然连不上etcd

etcd -advertise-client-urls=http://127.0.0.1:2379 
etcd -advertise-client-urls=http://etcd:2379

• milvus-etcd容器不向主机暴露任何端口，并将其数据映射到当前文件夹中的volumes/etcd。
• milvus-minio容器使用默认身份验证凭据在本地为端口9090和9091提供服务，并将其数据映射到当前文件夹中的volumes/minio。
• Milvus-standalone容器使用默认设置为本地19530端口提供服务，并将其数据映射到当前文件夹中的volumes/milvus。

整个服务包含三个服务 milvus-etcd, milvus-minio, milvus-standalone

2.2 milvus-standalone 单机版

端口：19530 9091

http://localhost:9091/healthz

2.3 etcd

用来存储元数据

2.4 minio

存储向量数据和索引数据

管理端：http://localhost:9001/login （密码在docker-compose 文件中）

2.2 关联界面 attu

官网：github.com/zilliztech/attu

Attu 版本需要和milvus的版本匹配

docker pull zilliz/attu:v2.5.3

以上程序attu无法连接到milvus 所以全部整和到一个网络中
