+# 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
+```shell
+$ wget https://raw.githubusercontent.com/milvus-io/milvus/master/deployments/docker/standalone/docker-compose.yml -O docker-compose.yml
+```
+&nbsp;&nbsp;&nbsp; or download Milvus cluster docker-compose.yml
+
+```shell
+$ 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
+```shell
+$ pip3 install -r requirements.txt
+$ python3 save_image.py --manifest docker-compose.yml
+```
+
+#### If you install Milvus with **Helm**, use these commands:
+#### 1. Update Helm repo
+```shell
+$ helm repo add milvus https://milvus-io.github.io/milvus-helm/
+$ helm repo update
+```
+
+#### 2. Get Kubernetes manifests of Milvus standalone
+```shell
+$ helm template my-release milvus/milvus > milvus_manifest.yaml
+```
+
+&nbsp;&nbsp;&nbsp;or get Kubernetes manifests of Milvus cluster
+
+```shell
+$ helm template --set cluster.enabled=true my-release milvus/milvus > milvus_manifest.yaml
+```
+
+#### 3. Pull and save Docker images
+```shell
+$ 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:
+
+```shell
+$ cd images/
+$ for image in $(find . -type f -name "*.tar.gz") ; do gunzip -c $image | docker load; done
+```
+
+### Step3: Install Milvus
+
+#### With Docker Compose
+
+```shell
+$ docker-compose -f docker-compose.yml up -d
+```
+#### On Kubernetes
+
+```shell
+$ kubectl apply -f milvus_manifest.yaml
+```
+
