don't try to love em. mostly just try not to get so wound up. resist the urge to form stromg opinions or to crave what you know. "scout mindset". just observe, try, learn. but here's some things about containers:
it's better than vm's. easier to manage, better extends the host rather than replacing it with a bunch of very non-uniform vm's.
it's nice having an abstraction to run & manage stuff, without having to learn to manage a bunch of particular languages or runtimes specifically. each container makes it's own tools true but there's still some general operations in common.
containers go nicely with "12 Factor" development (http://12factor.net). shared so standard baseline assumotions that should fit most jobs.
being able to snapshot & re-spaen new instances of containers is cool but almost never used.
I'm pretty not excited by containers. but we were doing a pretty weird hodgepodge of things before & a lot of it was kind of bogus but more so, just that there were so many competing styles. it was amateur. containers aren't super awesome but they're ok. they work pretty decently, and they make good use of a lot of really solid powerful kernel features that you should want to be using (croups).
