Milvus offline installation

Manually downloading Docker images

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 procedures:

Step 1: Save Milvus manifests and Docker images

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

1. Download Milvus standalone docker-compose.yml

   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.yml

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

2. Pull and save Docker images

   pip3 install -r requirements.txt
   python3 save_image.py --manifest docker-compose.yml
   

If you install Milvus with Helm, use these command:

1. Update Helm repo

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

2. Get Kubernetes manifests of Milvus standalone

   helm template my-release milvus/milvus > milvus_manifest.yaml
   

      or get Kubernetes manifests of Milvus cluster

   helm template --set cluster.enabled=true my-release milvus/milvus > milvus_manifest.yaml
   

3. 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.

Step 2: Load Docker images

Enter the following command to load the Docker images:

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