Cannot configure to deploy serverless stack to localstack

I am using serverless for deploying AWS serverless stack. (i.e: lambda, sqs, sns). I want to run before in local before trying to deploy to AWS. I have searched and see localstack suitable for my use case. Here is my step to deploy the system:

  1. Clone project and run whole stack using docker. (command: docker-compose up)
  2. Install library serverless-localstack and update serverless.yml in my project

Here is my config:

plugins:
  - serverless-localstack

custom:
  localstack:
    host: http://localhost
    debug: false
    endpoints:
    stages:
      - local
      - dev
    lambda:
      mountCode: False # Enable this flag to improve performance

After that, I deploy this stack using command: serverless deploy --stage local. But I always meet exception.

Serverless: Updating Stack...

I get the same error... I run sls deploy with SLS_DEBUG=3 and I can see that sls is trying to upload to s3 online, while I need it to use my local s3. I was not able to figure out how to fix it. The full log shows that it sets the TemplateURL: 's3.amazonaws.com/myproject-service-dev-deployment-bucket/…' - Christophe

I won’t say how to fix it, but maybe the problem is that you use a python and it is collected in a container lambci/lambda:build-python2.7. Perhaps the problem is to transfer the archive with the code between the containers - from lambci/lambda to localstack. I replay it with nodejs and everything is OK
