Create a CI Workflow with Minimal Boilerplate Using Nx, Docker, and GitHub Actions

A blueprint for setting up a hybrid CI workflow using Nx, Docker Compose, and GitHub Actions that works consistently in both local and CI environments. The guide covers configuring external services with Docker Compose profiles and DotenvX for environment variable management, setting up Nx Agents for distributed task execution, running the CI workflow locally with Act, and splitting E2E tests for parallelization. Key pitfalls are discussed, including a current limitation preventing Docker installation on non-enterprise Nx Cloud agents, which blocks fully distributed E2E testing.
