# 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
```
    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
```
   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
```
