localstack-demo

Demonstration case for localstack/localstack#253.

Demonstrate an error response with localstack lamba invoke, where it apparently cannot invoke nodejs functions (at least those created via zip).

Install

$ ./install.sh

Run

Start with docker-compose or directly:

With docker-compose (doesn't work)

$ docker-compose up -d

Direct (works)

$ . .venv/bin/activate
$ TMPDIR=/private$TMPDIR LAMBDA_EXECUTOR=docker localstack start --docker

Test

$ . .venv/bin/activate
$ ./test.sh

Expected Results

Successfully execute function, and log "Executed successfully"

Actual Results

Stopping localstackdemo_localstack_1 ... done
Removing localstackdemo_localstack_1 ... done
Removing network localstackdemo_default
