> How does Kubernetes not also result in the same?

Here's the difference between kubernetes and ansible (and alikes) (and I'm over-simplifying a bit of course, but the idea is there)

* With kubernetes, you write down the state you want your infrastructure to be in, and k8s figures out how to get there

* With ansible, you write down how to get to the state you want and ansible runs those steps, and hopefully they end up in the same state. The issue is that if you run the same set of steps on a Debian linux distribution, and on a Ubuntu distribution, well, they might end up in a similar state, but they actually aren't; for starters: one is debian, the other is unbuntu.

Kubernetes doesn't attempt to be an API that can solve any orchestration issue, it is an abstraction on the underlying architecture. It's a lot easier to be backwards compatible here (and if you are not, create an operator that is).

Now whether its the right abstraction is a matter of debate. But ultimately like VMs or containers, its so far proven to be a valuable tool, at least for medium sized companies.

One of the best things about K8s is its pretty stable API. We use GKE and the upgrades happen without issues 99% of the time.

The other benefit that k8s got for "free" was with containers: developers could stuff in whatever environment, software and configs they wanted inside the container. This removed most of the "my app broke because some shared lib didn't install properly" sorts of issues. This separation b/w software configuration and application configuration is extremely powerful.

Yea, I think with both ansible (and stuff like puppet) and kubernetes they are both powerful tools that are pretty leaky abstractions. They are great for sharing and implementing recipes, but that abstraction layer makes it a little more difficult to become a master chef and understand/control exactly what's happening. They are awesome to have in your toolbox, but I still find it incredibly useful to have a tool like python in there as well.

I’m not saying kube really fixes all of these problems or is a better solution, but it exists as a response to a crappy solution. in other words one problematic solution replaced another problematic solution. Stay in the field long enough and you see a pendulum where one kind of solution with problems is replaced by a different kind of solution with different problems... and then it swings back and a new general goes back to a new iteration of the first kind of solution and gets to rediscover the old problems again, back and forth over and over.

Who said it doesn't? Look at its schema it's horrific.

The reason it's popular is that it's backed by Google and solves problems Docker the company couldn't.

That doesn't mean k8s is by any means not suffering the same problems of being a dsl that should be something else.

It also doesn't mean k8s won't suffer the same weirdness between platforms (AWS vs GCE vs GKE).
