+# Docker Containers BKMs
+
+## Docker vs Podman
+
+Docker and Podman are very similar tools, that allow you to manage and run
+container images. Unlike Docker, Podman runs without a daemon, allows you to run
+containers without root permissions, but does not let you build a container from
+source. The command line syntax is mostly identical for Docker and Podman.
+Choose whatever is available on your system.
+
+## SYCL Containers overview
+
+The following containers are publicly available for DPC++ compiler development:
+
+- `ghcr.io/intel/llvm/ubuntu2004_base`: contains basic environment setup for
+   building DPC++ compiler from source.
+- `ghcr.io/intel/llvm/ubuntu2004_intel_drivers`: contains everything from base
+   container + pre-installed Intel drivers. This image provides two main tags:
+   `latest`, that uses latest available drivers, and `stable`, that uses
+   recommended drivers.
+- `ghcr.io/intel/llvm/ubuntu2004_nightly`: contains latest successfully built
+   nightly build of DPC++ compiler, as well as pre-installed Intel drivers.
+
+## Building a Docker Container from scratch
+
+Docker containers can be build with the following command:
+
+```
+docker build -f path/to/devops/containers/file.Dockerfile path/to/devops/
+```
+
+The `ubuntu2004_preinstalled.Dockerfile` script expects `llvm_sycl.tar.gz` file
+to be present in `devops/` directory.
+
+Containers other than base provide several configurable arguments, most commonly
+used are`base_image` and `base_tag`, that specify base Docker image and its tag.
+You can set additional arguments with `--build-arg ARG=value` argument.
+
+## Running Docker container interactively
+
+The main application of Docker is containerizing services. But it also allows
+you to run containers interactively, so that you can use it as you would use a
+terminal or SSH session. The following command allows you to do that:
+
+```
+docker run --name <friendly_name> -it --entrypoint /bin/bash <image_name>[:<tag>]
+```
+
+This command will download an image, if it does not exist locally. If you've
+downloaded an image previously, and you want to update it, use
+`docker pull <image_name>` command.
+
+## Passthrough an Intel GPU to container
+
+Add `--device=/dev/dri` argument to `run` command to passthrough you Intel GPU.
+
+## Passthrough a directory to container
+
+Use `-v path/on/host:path/in/container` argument for `run` command to
+passthrough a host directory or a file.
+
+## Managing downloaded Docker image
+
+List local images:
+```
+docker image ls
+```
+
+Remove local image:
+```
+docker image rm <image_name_or_id>
+```
