Docker containers are currently supported on Data Center nodes only. On Consumer nodes, docker containers are supported only when rented on a monthly basis.

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers.

To run docker containerized applications inside your Q Blocks instance you'd need the docker engine to be installed correctly with Nvidia GPU support.

## How to install Docker engine with GPU support?

Follow the steps below for successful installation:

1. Go to your Q Blocks instance and open the bash terminal in it.
2. Run the following command:

```bash
wget 'https://www.qblocks.cloud/resources/setup-docker-gpu.sh' --no-check-certificate -O - | bash
```

It should take 2-3 minutes of installation time and should return the following output:

"<mark style="color:green;">SUCCESSFULLY INSTALLED DOCKER WITH GPU SUPPORT.</mark>"

### How to use Docker with GPUs?

Once you have installed docker engine with GPU support in your Q Blocks instance, running a GPU enabled docker container is fairly straightforward.

For example, if you have 4 GPUs in your instance and you plan to use the first 2 GPUs out of them for a docker Image then simply run a command like this in your instance:

```bash
docker run --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES=0,1 -it DOCKER_IMAGE
```
