blambda's Issues

Add support for lambdas running on custom endpoints (e.g. localstack)

As far as I can tell, blambda uses the default AWS endpoint URL, which makes it incompatible with localstack.

Using a client such as the following would solve the problem:

    (aws/client {:api               :lambda
                 :region            aws-region
                 :endpoint-override {:protocol :http
                                     :hostname "localhost"
                                     :port     4566}})

Unfortunately AWS doesn't yet provide a way to set the endpoint in .aws/credentials or with an env var. Would you consider exposing the endpoint URL in the API as well as the CLI as an optional input, so that users can override the current behaviour?

Thanks a lot for blambda! It has simplified the process of writing lambdas in Clojure quite a bit :)

OS of loading pods

When I am trying to use pod from registry and a developing process is going on MacBook, command bb blambda build-deps-layer loads pod for MacOS, but definitely we need Linux pod for deployment to AWS Lambda.

I tried some workarounds like:

change os.name system property in pod loading moment, but as we can see in code of pods/load-pod it calls run-pod function, that starts process from binary and fails because of wrong OS
use resolve-pod instead of load-pod, that doesn't starts a binary, but it is in babashka.pods.impl, is unavailable and anyway will cause "code-smell"
build and deploy inside Docker image. It works so far, but sure need a bit engineering overhead

Getting error on running any subcommand

Hello! Thank you for library, but...

All attempts to run any subcommand are failing with such error:

Only simple bb blambda returns help as expected.
bb.edn file is simple also:

{:paths ["src"]
 :deps {net.jmglov/blambda
        {:git/url "https://github.com/jmglov/blambda.git"
         :git/tag "v0.1.0"
         :git/sha "b80ac1d"}}
 :tasks
 {:requires ([blambda.cli :as blambda])
  blambda {:doc "Controls Blambda runtime and layers"
           :task (blambda/dispatch
                  {:deps-layer-name "example-deps"
                   :lambda-name "example-test-1"
                   :lambda-handler "example.main/handler"
                   :lambda-iam-role "arn:aws:iam::******:role/service-role/example-test-1-role-******"
                   :source-files ["src"]})}}}

Please explain what could be wrong.
Thank you!
