使用docker和SQS的AWS Beanstalk上的Sinatra應用程序

我已經構建了一個簡單的sinatra應用程序，用於偵聽本地主機上的POST請求（包含來自AWS SQS的消息）並配置了dockerfile以便輕鬆部署。使用docker和SQS的AWS Beanstalk上的Sinatra應用程序

西納特拉：

set :environment, 'staging' 
set :bind, 'localhost' 
set :port, '80' 

before do 
    request.body.rewind 
    @request_payload = JSON.parse request.body.read 
end 

post '/' do 
    # do stuff with payload 
end

Dockerfile：

#https://dockerfile.github.io/#/ruby 
FROM dockerfile/ruby 

# Install dependencies 
RUN apt-get update 
RUN apt-get install postgresql-common postgresql-9.3 libpq-dev -y 

# Copy the Gemfile and Gemfile.lock into the image to cache bundle install 
# Temporarily set the working directory to where they are 
WORKDIR /tmp 
ADD ./Gemfile Gemfile 
ADD ./Gemfile.lock Gemfile.lock 
RUN bundle install 

# Copy code into the image 
ADD . /code 
WORKDIR /code 

# Open port 80 
EXPOSE 80 

# Clean up 
RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* 

# Default runtime command 
CMD /code/launcher.rb

但我得到的日誌文件這些錯誤：

任何想法？我認爲它與港口有關。我曾與其他人嘗試過沒有成功......

set :bind, 'localhost'指令是衝突。由於POST請求來自碼頭容器外部，Sinatra拒絕了連接。
