I don’t actually think there is a lot wrong with the 'traditional’ packaging apps into an OS native format, using config management to set up a VM and deploy into that. I can see the theoretical benefits of Docker, but the extra overhead and complexity, security and storage matters seem like a time sink. </div><div class=""><br class=""></div><div class="">I’ve dabbled with Docker in dev situations and built up a reasonably complex compose file that set up some home media components. I can see the appeal for large-scale environments where components need to be regularly updated as part of a scheduled release cycle, but issues around patching of the base containers and general workflow seemed rather nebulous. Abstracting away the underlying platform is appealing - all that’s needed in the runtime environment is a stock Docker OS (CoreOS, Atomic or Ubuntu seem the best candidates at the moment, but ), though the announcement of Dockers base OS is an interesting one.</div><div class=""><br class=""></div><div class="">I wonder if rkt will ultimately be the tooling of choice outside dev - it does away with the union filesystem, is more aligned to Kubernetes terminology, leverages other projects rather been an entirely self-contained eco-system as Docker is becoming. Though of course, they’ll recommend you run it on CoreOS :)</div><div class=""><br class=""></div><div class="">I think <a href="https://thehftguy.com/2017/02/23/docker-in-production-an-update/" class="">https://thehftguy.com/2017/02/23/docker-in-production-an-update/</a> and the comments there after raise a lot of good points.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Matt</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On 20 Apr 2017, at 10:27, David Goodwin via Swlug <<a href="mailto:swlug@mailman.lug.org.uk" class="">swlug@mailman.lug.org.uk</a>> wrote:</div><div class=""><div class=""><br class="">At $job-1 I built a hosting platform for (mostly) wordpress sites using LXC containers (with hindsight I chose the wrong technology - but at the time LXC seemed more mature with support for e.g. privilege separation).<br class=""><br class="">I think it's hosting about 2500 sites now - spread over about 20 VMs.<br class=""><br class="">So - they are "production ready".<br class=""><br class=""><br class="">But it does depend on the application(s).
