The same will eventually be said of Docker. I’ve yet to hear a single benefit attributed to Docker that isn’t also true of other VMs, but standard VMs allow the use of standard operating systems that solved all the hard problems decades ago, whereas Docker is struggling to solve those problems today.&lt;p&gt;Linux containerization (using the word &amp;quot;docker&amp;quot; for everything isn&amp;#x27;t right either) is an isolation + sandboxing mechanism, NOT a virtual machine. Even if you talk about things like LXC (orchestrated by LXD), that&amp;#x27;s basically just the addition of the user namespacing feature. A docker container is &lt;i&gt;not&lt;/i&gt; a VM, it is a regular process, isolated with the use of cgroups and namespaces, possibly protected (like any other process) with selinux&amp;#x2F;apparmor&amp;#x2F;etc.&lt;p&gt;Containerization is almost objectively a better way of running applications -- there&amp;#x27;s only one question, do you want your process to be isolated, or not. All the other stuff (using Dockerfiles, pulling images, the ease of running languages that require their own interpreters since you package the filesystem) is on top of this basic value propostion.&lt;p&gt;An easy way to tell that someone doesn&amp;#x27;t know what they&amp;#x27;re talking about when speaking about containerization is if they call it a VM (and don&amp;#x27;t qualify&amp;#x2F;note that they&amp;#x27;re being fast and loose with terminology).&lt;p&gt;All this said -- I do think Docker will die, and it &lt;i&gt;should&lt;/i&gt; die because Docker is no longer the only game in town for reasonably managing (see: podman,crictl) and running containers (see: containerd&amp;#x2F;cri-o, libcontainer which turned into runc) .&lt;p&gt;[EDIT] - I want to point out that I do &lt;i&gt;not&lt;/i&gt; mean the Docker the company or Docker the project will &amp;quot;die&amp;quot; -- they have done amazing things for the community and development as a whole that will literally go down in history as a paradigm shift. What I should have written was that &amp;quot;docker &amp;lt;x&amp;gt;&amp;quot; where x is &amp;quot;image&amp;quot;, &amp;quot;container&amp;quot;, &amp;quot;registry&amp;quot;, etc should be replaced by &amp;quot;container &amp;lt;x&amp;gt;&amp;quot;.</text></comment>

I’ve yet to hear a single benefit attributed to Docker that isn’t also true of other VMs,&lt;p&gt;I bought a Raspberry Pi and using a few commands, installed pre-configured Docker ARM images for 8-9 different media applications that would&amp;#x27;ve taken me days to setup and manage individually. I didn&amp;#x27;t have to worry about dependencies or compilations. It just worked.</text></comment>
