title: How to enable/disable buildkit in docker?
body: <p>I got this command from the documentation, but i really have no idea how can I use it or where should I start to move, I'm new to docker, and concepts are still hard to me to digest:</p>
  <pre><code>$ DOCKER_BUILDKIT=1 docker build .
  </code></pre>
  <p>How can I use this command to enable/disable buildkit in docker engine??</p>
  <p>I want to disable it, because as i knew it is enabled by default and i suspect it as i can't build anything by docker since i get always this error</p>
  <pre><code>failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount847288160/Dockerfile: no such file or directory
  </code></pre>
