Milvus offline installation

Manually downloading Docker images

Your Milvus installation may fail when images are not properly loaded from public Docker registries. To pull all images and save them into a directory that can be moved to the target host and loaded manually, perform the following procedure:

1. Save Milvus manifest and Docker images

If you install your Milvus with the docker-compose.yml file, use these command:

• Download Milvus docker-compose.yaml

# Download Milvus standalone docker-compose.yaml
wget https://raw.githubusercontent.com/milvus-io/milvus/master/deployments/docker/standalone/docker-compose.yml -O docker-compose.yml

or

# Download Milvus cluster docker-compose.yaml
wget https://raw.githubusercontent.com/milvus-io/milvus/master/deployments/docker/cluster/docker-compose.yml -O docker-compose.yml

• Pull and save Docker images

# Pull and save Docker images
pip3 install -r requirements.txt
python3 save_image.py --manifest docker-compose.yml

If you install your Milvus with Helm, use these command:

• Update Helm repo

helm repo add milvus https://milvus-io.github.io/milvus-helm/
helm repo update

• Get Kubernetes manifest of Milvus standalone

# Get Kubernetes manifest of Milvus standalone
helm template my-release milvus/milvus > milvus_manifest.yaml

or

# Get Kubernetes manifest of Milvus cluster
helm template --set cluster.enabled=true my-release milvus/milvus > milvus_manifest.yaml

• Pull and save Docker images

pip3 install -r requirements.txt
python3 save_image.py --manifest milvus_manifest.yaml

The Docker images will be stored under images directory.

2. Enter the following command to load the Docker images:

for image in $(find images/ -type f -name "*.tar.gz") ; do gunzip -c $image | docker load; done
