# Air-Gapped Environment Installation

> This tutorial explains how to download Docker containers from DockerHub and install the Visual Layer system in isolated, air-gapped environments

## Prerequisites

* Docker installed on your system
* Docker login credentials for Visual Layer repository

## Step 1: Docker Authentication

First, authenticategut with DockerHub using the provided credentials:

```bash theme={"theme":"monokai"}
docker login
```

When prompted, use:

* **Username**: visuallayer
* **Password**: Contact [support@visual-layer.com](mailto:support@visual-layer.com) and we will share the password

## Step 2: Required Docker Images

The Visual Layer system consists of the following Docker images that need to be pulled from DockerHub:

| Docker Image                     | Description                             |
| -------------------------------- | --------------------------------------- |
| `visuallayer/onprem-fe`          | Frontend web application interface      |
| `visuallayer/onprem-installer`   | Installation and setup utilities        |
| `visuallayer/onprem-healthcheck` | System health monitoring service        |
| `visuallayer/onprem-pl-cpu`      | CPU-based processing pipeline           |
| `visuallayer/onprem-pl-gpu`      | GPU-accelerated processing pipeline     |
| `visuallayer/onprem-pg`          | PostgreSQL database server              |
| `visuallayer/onprem-be`          | Backend API services                    |
| `visuallayer/onprem-cd`          | Continuous deployment service           |
| `visuallayer/onprem-model-pack`  | Pre-trained models and model management |

Pull all required images (replace `<VERSION>` with the specific version provided by Visual Layer support):

```bash theme={"theme":"monokai"}
# Pull all required images
docker pull visuallayer/onprem-fe:<VERSION>
docker pull visuallayer/onprem-installer:<VERSION>
docker pull visuallayer/onprem-healthcheck:<VERSION>
docker pull visuallayer/onprem-pl-cpu:<VERSION>
docker pull visuallayer/onprem-pl-gpu:<VERSION>
docker pull visuallayer/onprem-pg:<VERSION>
docker pull visuallayer/onprem-be:<VERSION>
docker pull visuallayer/onprem-cd:<VERSION>
docker pull visuallayer/onprem-model-pack:<VERSION>
```

## Step 3: Get Installation Script

First, obtain the `install_helper.sh` script. You can either download it using curl or request it from Visual Layer support:

```bash theme={"theme":"monokai"}
# Download the installation script
curl -fsSL https://vl-public-bucket.s3.us-east-2.amazonaws.com/installer/new/install_helper.sh -o install_helper.sh
```

Alternatively, contact [support@visual-layer.com](mailto:support@visual-layer.com) to get the script.

## Step 4: Run Installation

Replace `<VERSION>` with the specific version provided by Visual Layer support.

### For GPU-enabled Systems:

```bash theme={"theme":"monokai"}
HARDWARE=gpu VL_VERSION="<VERSION>" bash install_helper.sh
```

### For CPU-only Systems:

```bash theme={"theme":"monokai"}
HARDWARE=cpu VL_VERSION="<VERSION>" bash install_helper.sh
```

## Step 5: Verification

After installation, verify that all containers are running properly:

```bash theme={"theme":"monokai"}
docker ps
```

You should see all the Visual Layer containers running.

## Troubleshooting

* If containers fail to start, check the logs: `docker logs <container_name>`
* Ensure you have sufficient disk space for all images
* Verify network connectivity to DockerHub
* Make sure Docker daemon is running
