Why Use It

Docker mode helps catch:
  • missing dependencies,
  • Linux/runtime differences,
  • hardcoded local paths,
  • missing environment variables,
  • base image and adapter incompatibilities.

​
Limits

Local Docker is close to the cloud runtime, but not identical. Always run a staging or Store smoke test before relying on production behavior.
