I like them when I use them the same way I use BSD jails: providing a very thin amount of high-level resource isolation. And that&#x27;s it, because that&#x27;s all they are actually good at. That&#x27;s not, however, how the trend is to use them, and given the overwhelming, please-fund-us hype of the container movement, I&#x27;m not surprised you&#x27;re unimpressed. Containers emphatically do not replace virtualization (which, while it certainly has some drawbacks, at least <i>works as a developer will expect it to</i>, and yet the tooling all desperately wants you to believe it does because that&#x27;s how you&#x27;ll buy into their ~platform~ and their ~vision~ and be so very monetized on their behalf.<p>(Five point releases after promising this wouldn&#x27;t be the case anymore, Docker still doesn&#x27;t use user namespaces, so I really hope your Dockerfiles aren&#x27;t using root! Have fun.)
