Manage AWS Lambda functions using a Simiotics Function Registry

Project description


Manage AWS Lambda functions using a Simiotics Function Registry


pip install -U simiotics-lambada


This section lets you try out lambada using our example hello function.

First, export your SIMIOTICS_FUNCTION_REGISTRY environment variable. This tells lambada which Simiotics Function Registry to work with. If you do not have a private Simiotics account, you can use our free, public, and totally open registry:


Make sure that your AWS credentials are available either by exporting AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY or by ensuring that the profile you want to use is default in your AWS credentials file, or by exporting AWS_PROFILE. If you are not familiar with AWS authentication, you can read more here:

Decide on a key under which you would like to register the hello function into the Simiotics Function Registry. For example:

HELLO_KEY=hello-$(date -u +%s)

Register the function against the Simiotics Function Registry using lambada:

lambada register --key $HELLO_KEY \
    --code examples/hello/ \
    --handler hello \
    --requirements examples/hello/requirements.txt

Check that the function was successfully registered (if the output of the following command is empty, there is a problem):

lambada list | grep "$HELLO_KEY"

Create an AWS IAM role capable of executing the hello function and logging to CloudWatch:

lambada create_role --key $HELLO_KEY --name iam-lambada-demo

Deploy the function as an AWS Lambda:

lambada deploy --key $HELLO_KEY --name lambda-lambada-demo

This should return an AWS Lambda ARN of the form:

arn:aws:lambda:<REGION>:<PROJECT ID>:function:lambda-lambada-demo

Now you can invoke the deployed Lambda using the AWS command-line interface:

aws lambda invoke --function-name lambda-lambada-demo \
    --payload '{"target": "Sophia"}' \

To take down the AWS Lambda:

lambada down --key $HELLO_KEY

This only removes the AWS Lambda. It doesn't delete the IAM role. If you would like to get rid of that, as well:

lambada down --key $HELLO_KEY --teardown

Kick back, enjoy some smooth tunes, and let the Lambdas proliferate.
