title: Cannot start docker container In docker CE on oracle linux
body: <p>Recently I installed Docker CE on my Oracle Linux.<br>
  Unfortunately, when I want to start my first container with:</p>
  
  <pre><code>docker run hello-world
  </code></pre>
  
  <p>I get this error message:</p>
  
  <blockquote>
    <p>docker: Error response from daemon: OCI runtime create failed:
    container_linux.go:345: starting container process caused
    "process_linux.go:430: container init caused \"write
