Install Milvus Cluster with Docker Compose

This topic introduces how to deploy a Milvus cluster with Docker Compose.

Prerequisites

Check the requirements for hardware and software prior to your installation.

Download an installation file

Download milvus-cluster-docker-compose.yml directly or with the following command, and save it as docker-compose.yml.

$ wget https://github.com/milvus-io/milvus/releases/download/v2.0.2/milvus-cluster-docker-compose.yml -O docker-compose.yml

Start Milvus

$ sudo docker-compose up -d

Docker Compose is now in the Docker CLI, try `docker compose up`
Creating milvus-etcd   ... done
Creating milvus-minio  ... done
Creating milvus-pulsar ... done
Creating milvus-proxy      ... done
Creating milvus-rootcoord  ... done
Creating milvus-indexcoord ... done
Creating milvus-querycoord ... done
Creating milvus-datacoord  ... done
Creating milvus-querynode  ... done
Creating milvus-indexnode  ... done
Creating milvus-datanode   ... done

Check the status of the containers.

$ sudo docker ps

After Milvus cluster starts, 11 running docker containers appear including three dependencies and eight Milvus services.
