Running GitHub Actions Locally with nektos/act: Production Integration Lessons

Description and use

<h2> Why Local GitHub Actions Matter </h2> <p>When your CI pipeline burns through 2,000 runner minutes debugging a single YAML syntax error, the cost of cloud-only iteration becomes painfully clear. nektos/act solves this by executing GitHub Actions workflows locally using Docker containers that mirror the runner environment.</p> <p>After integrating nektos/act into our pre-push validation workflow, we caught 73% of configuration failures before they ever hit remote runners. But the devil lives in the compatibility layer.</p> <h2> The Reality Check: What Actually Works </h2> <p>nektos/act runs
