I'm trying to compile a 3rd party project and the project author provided a YAML file that outlines various GitHub Actions jobs for different environments. The file includes jobs for Windows, Linux, and formatting. However, I'm new to YAML and Docker, and I'm not sure how to execute or trigger a specific element (like a particular job or set of steps such as test-windows
or test-linux
).
I understand that YAML files can be used with Docker in some contexts, but this file appears to be a GitHub Actions workflow. How can I instruct it to run a certain job or step?
Below is an excerpt from the YAML file:
YAMLname: test on: push: branches: - '**' workflow_call: jobs: test-windows: runs-on: windows-2022 env: VS_PATH: C:\Program Files\Microsoft Visual Studio\2022\Enterprise MSBUILD_PATH: C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Current\Bin\MSBuild.exe steps: - uses: actions/checkout@v4 with: submodules: 'true' - name: Cache dependencies id: cache-deps uses: actions/cache@v3 env: cache-name: cache-deps with: path: windows/libraries key: ${{ runner.os }}-build-${{ env.cache-name }}-${{ hashFiles('tools/install_deps.py', 'dependencies.json') }}-v1 - if: ${{ steps.cache-deps.outputs.cache-hit != 'true' }} name: Install dependencies shell: cmd run: | pip install conan python tools/install_deps.py - name: Build libfwk, tests & tools shell: cmd run: | "%MSBUILD_PATH%" windows\libfwk.sln /p:Platform=x64 /p:Configuration=Debug - name: Run tests shell: cmd run: | build\test_stuff-x64-Debug\test_stuff.exe build\test_math-x64-Debug\test_math.exe test-linux: runs-on: ubuntu-22.04 steps: - uses: actions/checkout@v4 with: submodules: 'true' - name: Install Dependencies run: | wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add - sudo apt update sudo apt-get install libsdl2-dev libfreetype-dev libvorbis-dev libogg-dev libopenal-dev libdwarf-dev libelf-dev wget -qO - https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-jammy.list http://packages.lunarg.com/vulkan/lunarg-vulkan-jammy.list sudo apt update sudo apt install libvulkan-dev shaderc glslang-dev vulkan-headers - name: Build libfwk run: | make -j8 lib - name: Build tests & tools run: | make -j8 tests tools - name: Run tests run: | tests/stuff tests/math check-formatting: runs-on: ubuntu-22.04 steps: - uses: actions/checkout@v4 with: submodules: 'true' - name: Install Dependencies run: | wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add - sudo add-apt-repository 'deb http://apt.llvm.org/jammy/ llvm-toolchain-jammy-17 main' sudo apt update sudo apt install clang-format-17 pip install black - name: Check C++ formatting run: | python tools/format.py -c - name: Check Python formatting if: '!cancelled()' run: | python -m black tools/* --check --color --diff -l 100
I would appreciate guidance on how these jobs or steps can be triggered, either manually or locally, and what tools or configurations might be needed. Thanks!

This YAML file is a GitHub Actions workflow, not a standalone script or Docker Compose file. In other words, the elements you see (jobs like “test-windows” or “test-linux” and their steps) aren’t meant to be executed manually with a command; they are configuration for GitHub’s CI/CD system. Here’s how it works and what you can do:
Automatic Triggering:
The workflow is triggered by GitHub events (for example, a push). When you push code to a branch that matches the configured events (like any branch in this case), GitHub Actions will start executing the jobs (e.g., “test-windows”, “test-linux”, “check-formatting”) defined in the workflow.
Job Execution:
Each job specifies an operating system environment (using the runs-on
key) and a sequence of steps. The steps run one after the other in the virtual environment provided by GitHub.
No Manual “Element” Execution:
You cannot directly run a specific "job" or "step" by invoking the YAML file on your local machine. The workflow is meant to run as a whole when triggered by GitHub.
Pushing to GitHub:
To run these jobs, add your workflow file (typically placed in .github/workflows/
) in your GitHub repository and push a commit. GitHub will then trigger the workflow based on the event (e.g., push).
Using act for Local Testing:
If you want to run the workflows locally, you can use a tool like act. This CLI tool simulates GitHub Actions on your local machine. With act, you can run an entire workflow as GitHub would execute it.
For example, after installing act you can run:
BASHact -j test-windows
This command will execute the “test-windows” job locally (provided that the necessary environment for that job is set up or simulated).
This approach allows you to automate builds, tests, and other actions in a continuous integration environment.
