railpack

Configure and troubleshoot Railpack builds, with emphasis on RAILPACK_* environment variables, railpack.json overlays, build-plan inspection, local CLI installation and usage, and local BuildKit containers. Use for Railpack provider configuration, custom install/build/start commands, Mise or Apt packages, build or runtime variables and secrets, generated-plan debugging, BUILDKIT_HOST errors, or running Railpack from a release or source checkout.
