Documentation: Deploy Python Lambda functions with container images

Test the image locally

1 - Start the Docker image with the docker run command. In this example, docker-image is the image name and test is the tag.

docker run -p 9000:8080 docker-image:test

This command runs the image as a container and creates a local endpoint at localhost:9000/2015-03-31/functions/function/invocations.

2 - From a new terminal window, post an event to the following endpoint using a curl command:

curl "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{}'

3 - This command invokes the function with an empty event and returns a response. If you're using your own function code rather than the sample function code, you might want to invoke the function with a JSON payload. Example:

curl "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{"payload":"hello world!"}'

3 - Get the container ID.

docker ps

4 - Use the docker kill

command to stop the container. In this command, replace 3766c4ab331c with the container ID from the previous step.

docker kill 3766c4ab331c
