&quot;Docker is not an acceptable security solution for this, since it&#x27;s most certainly possible to break out of containers.&quot;<p>Could you point to some resources that show that it is possible to break out of Docker containers? I understand that there have been bugs in the past that have caused this (using that to conclude that glot.io shouldn&#x27;t use Docker is a bit like saying OpenSSL is now useless because of heartbleed) but it seems unlikely that breaking out of containers is possible due to the way Docker is designed.
