Confirm Docker status

Confirm that the Docker daemon is running in the background:

$ sudo docker info
  • If you do not see the server listed, start the Docker daemon.
  • On Linux, Docker needs sudo privileges. To run Docker commands without sudo privileges, create a docker group and add your users (see Post-installation steps for Linux for details).

Pull Docker image

Pull the CPU-only image:

$ docker pull milvusdb/milvus:0.10.0-cpu-d061620-5f3c00
If the pulling is too slow or fails constantly, see Operational FAQ for possible solutions.

Download configuration files

$ mkdir -p /home/$USER/milvus/conf
$ cd /home/$USER/milvus/conf
$ wget
If you cannot download configuration files via the wget command, you can create a server_config.yaml file under /home/$USER/milvus/conf, and then copy the content from server config to it.

Start Docker container

Start Docker container and map the paths to the local files to the container:

$ docker run -d --name milvus_cpu_0.10.0 \
-p 19530:19530 \
-p 19121:19121 \
-v /home/$USER/milvus/db:/var/lib/milvus/db \
-v /home/$USER/milvus/conf:/var/lib/milvus/conf \
-v /home/$USER/milvus/logs:/var/lib/milvus/logs \
-v /home/$USER/milvus/wal:/var/lib/milvus/wal \

The docker run options used in the above command are defined as follows:

  • -d: Runs container in the background and prints container ID.
  • --name: Assigns a name to the container.
  • --gpus: Assigns GPU devices to the container. ('all' represents all GPUs.)
  • -p: Publishes a container’s port(s) to the host.
  • -v: Mounts the directory into the container.

Confirm the running state of Milvus:

$ docker ps

If the Milvus server does not start up properly, check the error logs:

# Get the ID of the container running Milvus.
$ docker ps -a
# Check docker logs.
$ docker logs <milvus container id>
