Create a virtual environment for installing the requirements-dev.txt
$ /usr/local/opt/[email protected]/bin/python3 -m venv venv/python38
$ source venv/python38/bin/activate
$ python --version
> Python 3.8.3
Install the requirements
$ pip install -r requirements-dev.txt
Make a new chalice project
chalice new-project helloworld
In a separate terminal window, start localstack with
localstack start
Test helloworld app with local server for correct response. Change into helloworld directory and run chalice local.
cd helloworld
chalice local # or chalice-local local
In a separate terminal window, curl localhost:8000/ to get {"hello":"world"} 200 response. We can also verify correct response with the local server started by the chalice-local local command.
curl localhost:8000/
> {"hello":"world"}
Deploy helloworld app to localstack with
chalice-local deploy
> Creating deployment package.
> Creating IAM role: helloworld-dev
> Creating lambda function: helloworld-dev
> Creating Rest API
> Resources deployed:
> - Lambda ARN: arn:aws:lambda:us-east-1:000000000000:function:helloworld-dev
> - Rest API URL: https://xj0gy9hra9.execute-api.us-east-1.amazonaws.com/api/
In a separate terminal window, curl the rest api
curl http://localhost:4566/restapis/xj0gy9hra9/api/_user_request_/
> {"hello":"world"}
To clean up our resources deployed to localstack we can use
chalice-local delete
> Deleting Rest API: xj0gy9hra9
> Deleting function: arn:aws:lambda:us-east-1:000000000000:function:helloworld-dev
> Deleting IAM role: helloworld-dev
