title: "docker cp" all files from a folder to existing container folder
body: <p>Am I missing something when I try to copy files from one folder to a existing container folder:</p>
  
  <p><a href="https://docs.docker.com/reference/commandline/cp/" rel="noreferrer">Doc</a></p>
  
  <p>I want to copy files within the build(host) folder to html in my container:</p>
  
  <pre><code>docker cp ./src/build b081dbbb679b:/usr/share/nginx/html
  </code></pre>
  
  <p>To be clear; I need to copy from host to container.</p>
  
  <p>But it copies the whole build folder and copies it to ..html/build</p>
  
  <p>I just need the files(and sub folders) within the build folder to be copied into ..html.</p>
  
  <p>Am I missing something or do I have to copy each file one by one?</p>
