I had trouble understanding the benefits of it as well. A container is a snapshot of a specific version of an application/daemon and the OS it runs on all bundled into a deployable/runnable image. You create a container for every version of an app. Deploying or rolling back is almost as simple as deploying an image on any host that runs Docker.
- chrisper 9y agoThere is also the fact that things stay inside a container (more or less). You want to remove mysql? No problem, just discard the container. Compare that to removing mysql and all its config files etc. from all over the place.
- sigjuice 9y agoThe underlying problem is things like mysql that scatter things all over the place. Docker only encourages such sloppiness, IMHO.
- Godel_unicode 9y agoWhile it might be true that MYSQL being a bad roommate is the core problem, does that matter? As an admin you don't get to ignore the pager because the outage is Oracle's fault.
