@sphinxdirective
This guide provides steps on creating a Docker image with Intel® Distribution of OpenVINO™ toolkit for Linux and using the image on different devices.
System Requirements
###################
.. tab:: Target Operating Systems with Python Versions
+----------------------------------------------+-------------------------+
| Operating System | Included Python Version |
+==============================================+=========================+
| Ubuntu 18.04 long-term support (LTS), 64-bit | 3.8 |
+----------------------------------------------+-------------------------+
| Ubuntu 20.04 long-term support (LTS), 64-bit | 3.8 |

+----------------------------------------------+-------------------------+
.. tab:: Host Operating Systems
* Linux
* Windows Subsystem for Linux 2 (WSL2) on CPU or GPU
* macOS on CPU only
To launch a Linux image on WSL2 when trying to run inferences on a GPU, make sure that the following requirements are met:
* Only Windows 10 with 21H2 update or above installed and Windows 11 are supported.
* Intel GPU driver on Windows host with version 30.0.100.9684 or above need be installed. For more details,
`this article at intel.com <https://www.intel.com/content/www/us/en/artificial-intelligence/harness-the-power-of-intel-igpu-on-your-machine.html#articleparagraph_983312434>`__ .
* From 2022.1 release, the Docker images contain preinstalled recommended version of OpenCL Runtime with WSL2 support.
Installation
#############
* Use a prebuilt image:
1. `Get a prebuilt image from provided sources <getting-a-prebuilt-image-from-provided-sources>`__
2. `Run the image on different devices <running-the-docker-image-on-different-devices>`__
3. `Run samples in the Docker image <running-samples-in-docker-image>`__
* If you want to customize your image, you can also build a Docker image manually:
1. `Prepare a Dockerfile <preparing-a-dockerfile>`__
2. `Configure the Docker image <configuring-the-image-for-different-devices>`__
3. `Run the image on different devices <running-the-docker-image-on-different-devices>`__
4. `Run samples in the Docker image <running-samples-in-docker-image>`__
Getting a Prebuilt Image from Provided Sources
++++++++++++++++++++++++++++++++++++++++++++++
You can find prebuilt images on:
- `Docker Hub <https://hub.docker.com/u/openvino>`__
- `Red Hat Quay.io <https://quay.io/organization/openvino>`__
- `Red Hat Ecosystem Catalog (runtime image) <https://catalog.redhat.com/software/containers/intel/openvino-runtime/606ff4d7ecb5241699188fb3>`__
- `Red Hat Ecosystem Catalog (development image) <https://catalog.redhat.com/software/containers/intel/openvino-dev/613a450dc9bc35f21dc4a1f7>`__
- `Azure Marketplace <https://azuremarketplace.microsoft.com/en-us/marketplace/apps/intel_corporation.openvino>`__
Preparing a Dockerfile
++++++++++++++++++++++
You can use the `available Dockerfiles on GitHub <https://github.com/openvinotoolkit/docker_ci/tree/master/dockerfiles>`__
or generate a Dockerfile with your settings via `DockerHub CI Framework <https://github.com/openvinotoolkit/docker_ci>`__
which can generate a Dockerfile, build, test and deploy an image with the Intel® Distribution of OpenVINO™ toolkit.
You can also try our `Tutorials <https://github.com/openvinotoolkit/docker_ci/tree/master/docs/tutorials>`__
which demonstrate the usage of Docker containers with OpenVINO.
Configuring the Image for Different Devices
+++++++++++++++++++++++++++++++++++++++++++
If you want to run inference on a CPU no extra configuration is needed.
Go to `Run the image on different devices <running-the-docker-image-on-different-devices>`__ for the next step.
Configuring Docker Image for GPU
--------------------------------
By default, the distributed Docker image for OpenVINO has the recommended version of
Intel® Graphics Compute Runtime for oneAPI Level Zero and OpenCL Driver for the operating
system installed inside. If you want to build an image with a custom version of OpenCL Runtime included,
you need to modify the Dockerfile using the lines below (the 19.41.14441 version is used as an example) and build the image manually:
**Ubuntu 18.04/20.04**:
.. code-block:: sh
WORKDIR /tmp/opencl

chown openvino -R /home/openvino

Running the Docker Image on Different Devices
+++++++++++++++++++++++++++++++++++++++++++++
Running the Image on CPU
-------------------------
Run the Docker image with the following command:
.. code-block:: sh
docker run -it --rm <image_name>
Note the following:
- Kernel reports the same information for all containers as for native application,
for example, CPU, memory information.
- All instructions that are available to host process available for process in container,
including, for example, AVX2, AVX512. No restrictions.
- Docker does not use virtualization or emulation. The process in Docker is just a regular
Linux process, but it is isolated from external world on kernel level. Performance loss is minor.
Running the Image on GPU
-------------------------
.. note::
Only Intel® integrated graphics are supported.
Note the following:
- GPU is not available in the container by default. You must attach it to the container.
- Kernel driver must be installed on the host.
- In the container, non-root user must be in the ``video`` and ``render`` groups.
To add a user to the render group, follow the
`Configuration Guide for the Intel® Graphics Compute Runtime for OpenCL™ on Ubuntu 20.04 <https://github.com/openvinotoolkit/docker_ci/blob/master/configure_gpu_ubuntu20.md>`__.
To make GPU available in the container, attach the GPU to the container using ``--device /dev/dri`` option and run the container:
* Ubuntu 18 or RHEL 8:
.. code-block:: sh
docker run -it --rm --device /dev/dri <image_name>
.. note::
If your host system is Ubuntu 20, follow the
`Configuration Guide for the Intel® Graphics Compute Runtime for OpenCL™ on Ubuntu* 20.04 <https://github.com/openvinotoolkit/docker_ci/blob/master/configure_gpu_ubuntu20.md>`__.
* WSL2:
.. code-block:: sh
docker run -it --rm --device /dev/dxg --volume /usr/lib/wsl:/usr/lib/wsl <image_name>
.. note::
To launch a Linux image on WSL2, make sure that the additional `System Requirements <system-requirements>`__ are met.
Running Samples in Docker Image
###############################
To run the ``Hello Classification Sample`` on a specific inference device, run the following commands:
**CPU**:
.. code-block:: sh
docker run -it --rm <image_name>
/bin/bash -c "cd ~ && omz_downloader --name googlenet-v1 --precisions FP16 && omz_converter --name googlenet-v1 --precision FP16 && curl -O https://storage.openvinotoolkit.org/data/test_data/images/car_1.bmp && python3 /opt/intel/openvino/samples/python/hello_classification/hello_classification.py public/googlenet-v1/FP16/googlenet-v1.xml car_1.bmp CPU"
**GPU**:
.. code-block:: sh
docker run -itu root:root --rm --device /dev/dri:/dev/dri <image_name>
/bin/bash -c "omz_downloader --name googlenet-v1 --precisions FP16 && omz_converter --name googlenet-v1 --precision FP16 && curl -O https://storage.openvinotoolkit.org/data/test_data/images/car_1.bmp && python3 samples/python/hello_classification/hello_classification.py public/googlenet-v1/FP16/googlenet-v1.xml car_1.bmp GPU"
