Interventions tried

  • aws --version shows:
    aws-cli/1.16.94 Python/3.7.2 Darwin/18.2.0 botocore/1.12.84
  • reinstalled awscli and aws-sam-cli
  • brew doctor reports no error

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

  1. OS: MacOSX Mojave (10.14.2)
  2. sam --version:
    > SAM CLI, version 0.10.0

Add --debug flag to command you are running

I also faced the same issue.
In my case, I simply forgot to run a Docker service. After starting a Docker service on my machine, it resolved.

You didn't forget, docs just don't tell us to make it.

It's been a few days since I last posted this issue. In my case, I eventually moved away from AWS lambda to Google Cloud Functions. The documentation of GCF is easy to follow step by step; hello-world type of apps didn't fail; local emulator to test/debug GCF locally before deployment was also easy to use; and later I got my actual app working.

same here; just fire up docker and "problem" solved.
docs should be updated in order to advice this dependency

cheers!

The Quickstarts do link out to our installation docs which call out docker needs to be installed. What would make this clearer?

totally true @jfuss, I missed that link.
thanks

Closing this issue, as installations docs point to docker needing to be installed.
