问题
I have set-up a Cloud9 environment to develop and test lambda functions. To make the environment "cleaner" I have opted to use lambda layers to specify the function's dependencies. By doing this, I have removed the dependency folders from the environment, but I am now unable to test locally.
For example, I have a lambda layer for Stripe's python library. I am able to write a lambda function in Cloud9 referencing stripe, deploy the function, and successfully test the function remotely. But i am unable to run that function locally, as I get "unable to import stripe"
Is there a way to test a lambda function, that depends on a lambda layer, locally by specifying the layer ARN in Cloud9?
回答1:
Unfortunately, AWS Cloud9 does not support Lambda layers at the moment.
回答2:
AWS Cloud9 documentation says that is not supported to execute functions with layers from the AWS Resources window. But you can use sam local invoke or aws lambda on the Cloud9 terminal window. For instance
sam local invoke --event input.json --template ../template.yml <function_name>
will create a new docker image with the layer(s) dependencies that will be used to execute the lambda function. The TAG name is explained here
master:~/environment/ahdv (master) $ docker images
