Hi All, after I spent a lot of time configuring and connecting Logstash to Localstack, I had many errors and no guide to follow .

In my case I have 2 dockers , one is logstash docker with S3 output pluging , second docker is Localstack docker that emulates the AWS services.

I will paste docker-compose.yml and logstash config files to make it easy for you to do the same and save your time.

This is the config file for logstash , some simple input line generator

VERY IMPORTANT  
Keys - must be = "test"  
add "endpoint" to S3 output plugin with port 4566 , this is the only port after Localstack update on 09.2020  
add next lines to S3 output otherwise, you will have a lot of errors

> ```
> validate_credentials_on_root_bucket => "false"
> additional_settings => { "force_path_style" => true }
> 
> ```

Second docker-compose file for Localstack

> network_mode: bridge
> ports:

> - "4571:4571"
> - "${PORT_WEB_UI-8080}:${PORT_WEB_UI-8080}"       
> environment:

Do not forget to create a manually bucket you want to use in S3  
by running from cmd

> "aws --endpoint-url=[http://localhost:4566](http://localhost:4566) s3 mb s3://yourBucketName"

I hope it will save you a lot of time.

Goodluck.
