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 Milvus image

Pull the GPU-enabled image:

$ sudo docker pull milvusdb/milvus:0.10.1-gpu-d072020-bd02b1
  • If you cannot use your host to acquire Docker images and configuration files online because of network restrictions, please acquire them online from another available host, save them as a TAR file, pass it on to your local machine, and then load the TAR file as a Docker image:
    Sample code
    1. Save the Docker image as a TAR file, and pass it on to your local machine:
      $ docker save milvusdb/milvus > milvus_image.tar
    2. Load the TAR file as a Docker image:
      $ docker load < milvus_image.tar
  • If pulling the docker image is too slow or keeps failing, see Operational FAQ for solutions.

Download configuration files

$ mkdir -p /home/$USER/milvus/conf
$ cd /home/$USER/milvus/conf
$ wget https://raw.githubusercontent.com/milvus-io/milvus/v0.10.1/core/conf/demo/server_config.yaml
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.

After you downloaded the configuration file, you must set enable to true in gpu section of server_config.yaml.

Start Docker container

Before starting Docker container, you must set enable to true in gpu section of server_config.yaml.

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

$ sudo docker run -d --name milvus_gpu_0.10.1 --gpus all \
-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 \
milvusdb/milvus:0.10.1-gpu-d072020-bd02b1

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:

$ sudo docker ps

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

$ sudo docker logs milvus_gpu_0.10.1
