# Deployment Examples

This document provides deployment examples for running the application in different environments.

Choose the deployment option that best fits your setup.

- **[Local GPU NVIDIA](#local-gpu-nvidia)**: For deploying the application locally on a machine with a supported NVIDIA GPU (using Docker Compose).
- **[Local GPU AMD](#local-gpu-amd)**: For deploying the application locally on a machine with a supported AMD GPU (using Docker Compose).
- **[OpenShift](#openshift)**: For deploying the application on an OpenShift cluster, designed for cloud-native environments.

## Local GPU NVIDIA

### Docker compose

Manifest example: [compose-nvidia.yaml](./deploy-examples/compose-nvidia.yaml)

This deployment has the following features:

- NVIDIA cuda enabled

Install the app with:

```sh
docker compose -f docs/deploy-examples/compose-nvidia.yaml up -d
```

For using the API:

```sh
# Make a test query
curl -X 'POST' \
  "localhost:5001/v1/convert/source/async" \
  -H "accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
    "http_sources": [{"url": "https://arxiv.org/pdf/2501.17887"}]
  }'
```

<details>
<summary><b>Requirements</b></summary>

- debian/ubuntu/rhel/fedora/opensuse
- docker
- nvidia drivers >=550.54.14
- nvidia-container-toolkit

Docs:

- [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/supported-platforms.html)
- [CUDA Toolkit Release Notes](https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#id6)

</details>

<details>
<summary><b>Steps</b></summary>

1. Check driver version and which GPU you want to use 0/1/2/n (and update [compose-nvidia.yaml](./deploy-examples/compose-nvidia.yaml) file or use `count: all`)

    ```sh
    nvidia-smi
    ```

2. Check if the NVIDIA Container Toolkit is installed/updated

    ```sh
    # debian
    dpkg -l | grep nvidia-container-toolkit
    ```

    ```sh
    # rhel
    rpm -q nvidia-container-toolkit
    ```

    NVIDIA Container Toolkit install steps can be found here:

    <https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html>

3. Check which runtime is being used by Docker

    ```sh
    # docker
    docker info | grep -i runtime
    ```

4. If the default Docker runtime changes back from 'nvidia' to 'default' after restarting the Docker service (optional):

    Backup the daemon.json file:

    ```sh
    sudo cp /etc/docker/daemon.json /etc/docker/daemon.json.bak
    ```

    Update the daemon.json file:

    ```sh
    echo '{
      "runtimes": {
        "nvidia": {
          "path": "nvidia-container-runtime"
        }
      },
      "default-runtime": "nvidia"
    }' | sudo tee /etc/docker/daemon.json > /dev/null
    ```

    Restart the Docker service:

    ```sh
    sudo systemctl restart docker
    ```

    Confirm 'nvidia' is the default runtime used by Docker by repeating step 3.

5. Run the container:

    ```sh
    docker compose -f docs/deploy-examples/compose-nvidia.yaml up -d
    ```

## Local GPU AMD

### Docker compose

Manifest example: [compose-amd.yaml](./deploy-examples/compose-amd.yaml)

This deployment has the following features:

- AMD rocm enabled

Install the app with:

```sh
docker compose -f docs/deploy-examples/compose-amd.yaml up -d
```

For using the API:

```sh
# Make a test query
curl -X 'POST' \
  "localhost:5001/v1/convert/source/async" \
  -H "accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
    "http_sources": [{"url": "https://arxiv.org/pdf/2501.17887"}]
  }'
```

<details>
<summary><b>Requirements</b></summary>

- debian/ubuntu/rhel/fedora/opensuse
- docker
- AMDGPU driver >=6.3
- AMD ROCm >=6.3

Docs:

- [AMD ROCm installation](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/install/quick-start.html)

</details>

<details>
<summary><b>Steps</b></summary>

1. Check driver version and which GPU you want to use 0/1/2/n (and update [compose-amd.yaml](./deploy-examples/compose-amd.yaml) file)

    ```sh
    rocm-smi --showdriverversion
    rocminfo | grep -i "ROCm version"
    ```

2. Find both video group GID and render group GID from host (and update [compose-amd.yaml](./deploy-examples/compose-amd.yaml) file)

    ```sh
    getent group video
    getent group render
    ```

3. Build the image locally (and update [compose-amd.yaml](./deploy-examples/compose-amd.yaml) file)
