docker-lambda VS Moto

Step 2: Push a container from your local machine to ECR. Currently, I use sample python lambda docker from https://github.com/lambci/docker-lambda.git

You can see the following projects for some examples of using this plugin to build a layer. They all leverage Docker and the docker-lambda images to compile for AWS’s Lambda environment on any operating system:

I end up using Lambda a lot so lambci is very useful for local testing: https://github.com/lambci/docker-lambda

There are kind souls in this world who created this: https://github.com/lambci/docker-lambda

If all you need is the ability to run a lambda function's code locally you might interested in docker-lambda[1]. I haven't really used localstack or SAM but a couple of years ago when we needed to run some lambda functions locally for development docker-lambda worked well enough.

Docker Lambda — Docker Lambda is a tool which tries to replicate the AWS Lambda environment as closely as possible, but within a Docker container. Docker Lambda has support for most of the AWS Lambda run times.

Want to emulate AWS environments? Try docker-lambda.

> OpenMoto

I dunno if you're trying to play on "hashimoto" but https://github.com/getmoto/moto#readme would be a prime name collision for any such "OpenMoto" name

But yes, please, to adopting Vault. I don't have a horse in the race about Consul but my suspicion is such an effort would only be worthwhile if trying to adopt Nomad, too, which I gravely doubt

Unfortunately I do not believe AWS provides any "test" gateways. I do know there are mock AWS servers you can run on your own. The one I use is called Moto. It does not cover everything (unfortunately it's the most comprehensive out there AFAIK), but it's decent enough to test most standard calls via the sdk. I'm not sure if it covers authorization though...we tend to use security roles on tasks for authorization.

If using Python use Moto to mock AWS Services

You can use a library such as moto https://github.com/getmoto/moto

The Pythonic motto library mocks AWS services, removing the need to deploy your application or pay for API calls against AWS services. Other programming languages have their motto implementation.

Has anyone managed to configure moto (https://docs.getmoto.org/en/latest/) in a docker container in the similar way LocalStack does?

As for mocking, you can take a look at the moto library for mocking the AWS SDK, or for more simple cases even just use a `unittest.Mock/MagicMock` object. If you're having trouble trying to use the mocks in your code, it's a good sign your code is too highly coupled and it'd pay to re-factor, for example using dependency injection, design patterns like adapter/facade etc. (but don't over-do it)

To add on to the integration tests point, for mocking out your AWS resources you should check out moto if you don't want run your test against real AWS resources as they may cost you and is usually slower.
