test: add GitHub Actions workflow for Docker integration tests

[ajcasagrande]

Summary by CodeRabbit

• Chores
  • Established automated Docker-based integration testing infrastructure that runs on all pull requests and commits to the main branch. Tests execute within containerized environments using parallelized execution to improve code validation consistency and reduce deployment risks.

Quick install:

pip install --upgrade --force-reinstall git+https://github.com/ai-dynamo/aiperf.git@ajc/docker-tests

Recommended with virtual environment (using uv):

uv venv --python 3.12 && source .venv/bin/activate
uv pip install --upgrade --force-reinstall git+https://github.com/ai-dynamo/aiperf.git@ajc/docker-tests

Walkthrough

A new GitHub Actions workflow is added that automates Docker-focused integration testing. The workflow triggers on pull requests and pushes to main, builds a Docker image using Buildx, runs a container with the repository mounted, installs dependencies, and executes integration tests with specific marker filters and parallelization.

Changes

Cohort / File(s)	Summary
Docker Integration Test Workflow .github/workflows/docker-integration-tests.yml	New workflow file that defines a CI pipeline for Docker-based integration testing, including Docker image build and push steps, container execution with mounted volumes, Python virtual environment activation, dependency installation, and pytest execution with marker filtering and parallel test execution.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Docker Buildx configuration (context, target, caching) correctness and alignment with project structure
• Test marker filtering logic (integration and not performance and not stress) to ensure intended test scope
• Virtual environment and dependency installation within container
• Pytest parallelization settings and output verbosity configuration

Poem

🐰 A workflow springs forth, Docker-bound and bright,
Building images, testing through the night,
Containers spin with Python's embrace,
Integration tests dash at quickened pace! 🏃‍♂️✨

1-39: All verifications passed—workflow configuration is correct.

The Docker integration tests workflow is properly configured:

• ✓ Venv at /opt/aiperf/venv/bin/activate is created in the env-builder target and correctly copied to the final image
• ✓ uv is installed from the official ghcr.io/astral-sh/uv:latest image and available in the container
• ✓ tests/integration/ directory exists with proper pytest markers (@pytest.mark.integration, @pytest.mark.stress) that match the workflow's test selection
