title: Adding custom seccomp profile in docker
body: <p>I am trying to use a custom <code>seccomp</code> profile with <code>docker run</code> command; however, I invoked with the following error-</p>
  <pre><code>$ sudo docker run --rm -it --security-opt seccomp=/home/temp/default.json ubuntu
  docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: error adding seccomp filter rule for syscall clone3: permission denied: unknown.
  $ docker -v
  Docker version 20.10.8, build 3967b7d
  </code></pre>
  <p>What would be the possible cause for this issue?</p>
  <p>Note that, I have modified the default <code>seccomp</code> profile file to enable the Linux <code>perf tool</code> (I have followed <a href="https://stackoverflow.com/a/54966080/3862410">this post</a>).</p>
