apologise for the rerun. <br>
<br>
I am working on migrating a LAMP application -- Drupal, as it turns<br>
out -- from a VPS on Linode onto a different VPS on Linode. (Yes, I<br>
really want to migrate to a new instance and not just upgrade the<br>
existing one.)<br>
<br>
It seems that Docker is the cool new thing to use for deploying<br>
applications. It sounds as if Docker is good for scaling things out,<br>
and for allowing different versions of LAMP components (different<br>
versions of PHP, for example) to exist on the same VPS when they are<br>
used by different applications. But does it make sense if you are<br>
sticking with a standard LAMP configuration on a standard Ubuntu<br>
install? It might be possible to containerize this application, but<br>
would it be worth the trouble? What advantages would there be?<br>
<br>
I am also confused how one keeps all of these containerized images up<br>
to date, and even why I should trust images that come from<br>
<a href="http://hub.docker.com" rel="noreferrer" target="_blank">hub.docker.com</a> . I trust Ubuntu/Debian updates because I understand<br>
the social infrastructure that makes them relatively trustworthy. I<br>
also understand that I can upgrade these components with an "apt<br>
upgrade". I do not know how people do this in the Docker world.<br>
<br>
Help? There are a bunch of tutorials in getting started with Docker,<br>
but not much about when to choose it, and under what situations it<br>
does/does not make sense.<br>
