Configure Milvus with Docker Compose

This topic describes how to configure Milvus components and its third-party dependencies with Docker Compose.

In current release, all parameters take effect only after Milvus restarts.

Download a configuration file

Download milvus.yaml directly or with the following command.

$ wget https://raw.githubusercontent.com/milvus-io/milvus/v2.4.5/configs/milvus.yaml

Modify the configuration file

Configure your Milvus instance to suit your application scenarios by adjusting corresponding parameters in milvus.yaml.

Check the following links for more information about each parameter.

Quota and Limits

Download an installation file

Download the installation file for Milvus standalone, and save it as docker-compose.yml.

You can also simply run the following command.

# For Milvus standalone
$ wget https://github.com/milvus-io/milvus/releases/download/v2.4.5/milvus-standalone-docker-compose.yml -O docker-compose.yml

Modify the installation file

In docker-compose.yml, add a volumes section under each milvus-standalone.

Map the local path to your milvus.yaml file onto the corresponding docker container paths to the configuration files /milvus/configs/milvus.yaml under all volumes sections.

...
  standalone:
    container_name: milvus-standalone
    image: milvusdb/milvus:v2.2.13
    command: ["milvus", "run", "standalone"]
    environment:
      ETCD_ENDPOINTS: etcd:2379
      MINIO_ADDRESS: minio:9000
    volumes:
      - /local/path/to/your/milvus.yaml:/milvus/configs/milvus.yaml   # Map the local path to the container path
      - ${DOCKER_VOLUME_DIRECTORY:-.}/volumes/milvus:/var/lib/milvus
    ports:
      - "19530:19530"
      - "9091:9091"
    depends_on:
      - "etcd"
      - "minio"
...
Data are stored in the /volumes folder according to the default configuration in docker-compose.yml. To change the folder to store data, edit docker-compose.yml or run $ export DOCKER_VOLUME_DIRECTORY=.

Start Milvus

Having finished modifying the configuration file and installation file, you can then start Milvus.

$ sudo docker compose up -d
