Download an installation file
Download the installation file for Milvus standalone or cluster, 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/v2.1.4/milvus-standalone-docker-compose.yml -O docker-compose.yml
# For Milvus cluster
$ wget https://github.com/milvus-io/milvus/releases/download/v2.1.4/milvus-cluster-docker-compose.yml -O docker-compose.yml
Modify the installation file
In docker-compose.yml, add a volumes section under each Milvus component, i.e. root coord, data coord, data node, query coord, query node, index coord, index node, and proxy.
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.
...
proxy:
container_name: milvus-proxy
image: milvusdb/milvus:v2.1.0-20220928-9122e34c
command: ["milvus", "run", "proxy"]
volumes: # Add a volumes section.
- /local/path/to/your/milvus.yaml:/milvus/configs/milvus.yaml # Map the local path to the container path
environment:
ETCD_ENDPOINTS: etcd:2379
MINIO_ADDRESS: minio:9000
PULSAR_ADDRESS: pulsar://pulsar:6650

...
/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=.
