title: How to run python scripts after CMD in Dockerfile?
body: <p>I have a docker image that exposes 9000 port for server. After the server is running, I need to execute the 3 python scripts which depends on server so, they can only get executed after server.py is running however, after CMD command, the other code do not get executed and remains stuck. What are the possible suggestion to run 3 scripts in same container?</p>
  <pre><code>FROM python:3.7.3 as build
  
  WORKDIR /app
  
  COPY requirements.txt .
  
  RUN pip install --no-cache-dir -r requirements.txt
  
  COPY . . 
  
  # CMD [ &quot;python&quot;, &quot;./server.py&quot; ]   (The following 3 scripts depends on server.py for execution)
  
  RUN python /app/script1.py
  RUN python /app/script2.py
  RUN python /app/script3.py
  
  EXPOSE 9000
  
  CMD [ &quot;python&quot;, &quot;./server.py&quot; ]
  </code></pre>
