Problem

I am having trouble debugging a lambda locally using sam + aws toolkit + rancher desktop (dockerd). The debugger never makes it to the breakpoint set withing my lambda.
However, when I quit rancher desktop and open docker desktop, not making any changes, the debugger hits the desired breakpoint.
Using rancher desktop due to work constraints.

Steps to reproduce the issue

Use the aws toolkit wizard to create the basic python3.7 (image) HelloWorld lambda, leaving all defaults as is with rancher desktop 1.9.1 (dockerd).

    Value: !GetAtt HelloWorldFunction.Arn
  HelloWorldFunctionIamRole:
    Description: "Implicit IAM Role created for Hello World function"

Expected behavior

The debugger should stop at the desired breakpoint within the lambda.

Thanks for the very clear report! Rancher is reported as working with SAM CLI but it requires some setup. Some notes are in #3413 , starting with this comment: #3413 (comment)

I need to add another piece of the puzzle: I get a "Failed to attach debugger" error sometimes:

Looks like I missed a very important detail from aws/aws-sam-cli#3595 (comment):

If you are a Mac/Windows user:
If the Docker Desktop is not installed in MacOS or Windows, the following commands and options will not work:

  • sam build --use-container
  • sam build when you specify a Dockerfile and OCI Image as your packaging format
  • sam local invoke
  • sam local start-api
  • sam local start-lambda

which are all the command options I need for debugging lambdas locally.
So Rancher won't work. I will need to switch to either one of these:

  • macOS and Colima
  • Docker CLI and Docker Engine inside a virtual machine with Linux system

Thank you for the help @justinmk3

Troubleshooting steps mentioned in aws/aws-sam-cli#5646 (comment) may be useful:

  1. Use docker context inspect to find the socket location
  2. Export DOCKER_HOST (and start vscode from the same terminal to ensure that it inherits the DOCKER_HOST environment variable)
