Install Milvus Offline with Helm Charts

This topic describes how to install Milvus with Helm charts in an offline environment.

Installation of Milvus might fail due to image loading errors. You can install Milvus in an offline environment to avoid such problem.

Download files and images

To install Milvus offline, you need to pull and save all images in an online environment first, and then transfer them to the target host and load them manually.

1. Add and update Milvus Helm repository locally.

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

2. Get a Kubernetes manifest.

• For Milvus standalone:

helm template my-release --set cluster.enabled=false --set etcd.replicaCount=1 --set minio.mode=standalone --set pulsar.enabled=false milvus/milvus > milvus_manifest.yaml

• For Milvus cluster:

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

If you want to change multiple configurations, you can download a value.yaml file, specify configurations in it, and generate a manifest based on it.

wget https://raw.githubusercontent.com/milvus-io/milvus-helm/master/charts/milvus/values.yaml
helm template -f values.yaml my-release milvus/milvus > milvus_manifest.yaml

3. Download requirement and script files.

$ wget https://raw.githubusercontent.com/milvus-io/milvus/master/deployments/offline/requirements.txt
$ wget https://raw.githubusercontent.com/milvus-io/milvus/master/deployments/offline/save_image.py

4. Pull and save images.

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

5. Load the images.

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

Install Milvus offline

Having transferred the images to the target host, run the following command to install Milvus offline.

kubectl apply -f milvus_manifest.yaml

Uninstall Milvus

To uninstall Milvus, run the following command.
