I am sorry you feel hurt, but you have misunderstood the post. Docker really is great -- and like the post says, it really does let you do everything you want. But for JVM applications, Capsule is much easier and faster, requires fewer steps and fewer tools, and launches containers that are more secure and easier to monitor and manage. Docker doesn&#x27;t prevent you from doing all that (well, except for the security bit), but it does add extra work and an extra layer of inconvenience compared to Capsules. Capsules are a JAR file built by your chosen build-tool that require no set up, configuration etc.. You can launch them as a simple executable JAR, or, if you wish, optionally launch them in a container. Docker isn&#x27;t inferior by any means. It is simply less streamlined -- <i>for the JVM</i> -- than a solution that is specifically tailored for the JVM. That&#x27;s it.
