Answer 1

You Carrierwave inside docker container should point to the service DNS in your case following change should work

CarrierWave.configure do |config|
  config.fog_provider = 'fog/aws'
  config.fog_credentials = {
      provider:              'AWS',
      aws_access_key_id:     'development',
      aws_secret_access_key: 'development',
      region:                'us-east-1',
      host:                  'minio',
      endpoint:              'http://minio:9000'
  }
  config.fog_directory  = 'test'
  config.fog_public     = false
  # config.fog_attributes = { cache_control: "public, max-age=#{365.day.to_i}" } # optional, defaults to {}
end

Adding to previous answer you should also add 'path_style' => true to your config
