Install Milvus

Botastic uses Milvus as its vector database. To simplify the installation process, we provide a docker-compose file to deploy Milvus.

Edit docker-compose.yaml

Create a folder named milvus and put a docker-compose.yaml file with the following content in it.

It exposes two ports, which you can replace with easy-to-manage ports.

  • 19530 - milvus gRPC service port.
  • 19531 - port for management GUI.
version: "3.5"

services:
  etcd:
    container_name: milvus-etcd
    image: quay.io/coreos/etcd:v3.5.5
    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

  standalone:
    container_name: milvus-standalone
    image: milvusdb/milvus:v2.2.3
    command: ["milvus", "run", "standalone"]
    environment:
      ETCD_ENDPOINTS: etcd:2379
    volumes:
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/milvus:/var/lib/milvus
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/milvus_config/milvus.yaml:/milvus/configs/milvus.yaml
    ports:
      - "19530:19530"
      # - "9091:9091"
    depends_on:
      - "etcd"

  attu:
    container_name: milvus-attu
    image: zilliz/attu:latest
    environment:
      MILVUS_URL: standalone:19530
    ports:
      - "19531:3000"
    depends_on:
      - "standalone"

networks:
  default:
    name: milvus

Create the milvus.yaml config file.

Execute the folling command to download the milvus.yaml file.

cd milvus
mkdir -p volumes/milvus_config
cd volumes/milvus_config
wget https://raw.githubusercontent.com/milvus-io/milvus/v2.2.3/configs/milvus.yaml

The tree command output as following,

cd milvus
tree
.
├── docker-compose.yml
└── volumes
    └── milvus_config
        └── milvus.yaml

Edit the milvus.yaml file

Edit the minio section of the milvus.yaml file to config the S3 storage.

If you are not sure about the configuration you can refer to MinIO's documentation.

# ...

minio:
  address: CHANGE_ME # Address of MinIO/S3
  port: 80 # Port of MinIO/S3
  accessKeyID: CHANGE_ME # accessKeyID of MinIO/S3
  secretAccessKey: CHANGE_ME # MinIO/S3 encryption string
  useSSL: false # Access to MinIO/S3 with SSL
  bucketName: CHANGE_ME # Bucket name in MinIO/S3
  rootPath:
    "files" # The root path where the message is stored in MinIO/S3
  useIAM: false
  cloudProvider: "aws"
  iamEndpoint: ""

# ...

Start the service

check the service status to ensure that the service started successfully.

cd milvus
docker compose up -d
docker compose ps
