Tianocore Containers

This is a Tianocore maintained project for container images used to build and test Edk2 based UEFI firmware code projects. This repository contains the dockerfiles and the github workflow files to generate these container images. Container images are automatically build and uploaded to the associated github container registry. Links to the container registry for the various images can be found in current status.

Container Types

Containers will be broken up into the following types based on their intended use. Additional types may be added in the future to accommodate new use cases.

Build

Build images will only have a minimal set of tools intended to be used for building the firmware projects. They will not contain virtualization or other tools used for testing or development.

Test

Usually built on top of a corresponding build image, test images will additionally contain tools and packages used for testing the firmware. For example, test images will contain QEMU for testing a virtualized platform.

Dev

Intended for local use to develop for EDKII based UEFI products.

Using containers locally

Containers can provide a convenient and consistent development environment when building EDK2 based firmware projects. This section details some tools and tips that make using containers for local development easier. The DEV editions of the containers are intended for this purpose. This section is not comprehensive however and it is encouraged users experiment and consider contributing back any new useful configurations or tools to this documentation.

NOTE: If your code base is cloned in Windows, it is not advised that you directly open this repository in a Linux dev container as the file system share between Windows and WSL 2 causes a very significant performance reduction. Instead, clone the repo in the WSL file system and map into the container or directly clone into the container.

Visual Studio Code

The Visual Studio Code Dev Container extension provides an easy and consistent way to use containers for local development. At the time of writing, this extension only supports Linux based containers. This extension provides a number of useful additions to the specified docker image on creation.

  • Configures git credential manager to pipe in git credentials.
  • Makes extensions available on code inside the container.
  • Abstracts management of the container for seamless use in the editor.

For a shared docker image configuration, this can be configured by creating a .devcontainer file in the repository. Some useful configurations are details below.

Configuration Purpose
"privileged": true This may be needed for access to KVM for QEMU acceleration.
"forwardPorts": [####] Can be used to forward debug or serial ports to the host OS.

It may also be desireable to run initialization commands using the "postCreateCommand" option. Specifically running git config --global --add safe.directory ${containerWorkspaceFolder} may be required if mapping the repository into the container is expected.

And example of a devcontainer used for a QEMU platform repo is included below.

{
  "image": "ghcr.io/tianocore/containers/fedora-35-dev:latest",
  "postCreateCommand": "git config --global --add safe.directory ${containerWorkspaceFolder} && pip install --upgrade -r pip-requirements.txt",
  "forwardPorts": [5000],
  "privileged": true
}

Notes

Ubuntu

The Ubuntu 'dev' images are suitable for development and uses a non-standard entry-point script which changes the user inside the container to match the outside user and expects the users home directory to be shared. They can be run like this (changing ubuntu-XX to the appropriate version, such as ubuntu-22):

docker run -it \
       -v "${HOME}":"${HOME}" -e EDK2_DOCKER_USER_HOME="${HOME}" \
       ghcr.io/tianocore/containers/ubuntu-XX-dev:latest /bin/bash

To enter the container as 'root', prepend the command to run with su, for example

docker run -it \
       -v "${HOME}":"${HOME}" -e EDK2_DOCKER_USER_HOME="${HOME}" \
       ghcr.io/tianocore/containers/ubuntu-XX-dev:latest su /bin/bash

The images provide the "edkrepo" tool.
