For a very long time there was a gaping security hole in Docker: anyone who could run a container could mount anything on the underlying host as root. This says to me that Docker (the company) don’t really consider any use cases beyond “fooling around on a personal laptop”. Meanwhile other container projects took seriously from day 1 that they would need to run in production.

Docker (the company) certainly helped to raise the profile of containerisation but they invented very little of it and did a poor job of implementing what they did do. Good riddance to them.

The problem i have with cubernetes is the following: I as a small developer and small server owner don't have the ressources to even get started. The first thing i see at cubernetes is a cluster. Why a cluster. Do i need to cluster my Raspberry pi's to get something out of it? Do i need to buy 3 servers just to run 5 containers? In docker its easy. Download Docker. Start container. Install container manager like plat…

You don't need a whole cluster to get started, you can use Minikube locally for example : https://minikube.sigs.k8s.io/docs/

Docker and Kubernetes are on completely different layers. You can't do those comparisons.

Kubernetes is like an operating system, Docker is like a format for the executable files.

There is no problem with servers. We're running Kubernetes in production on a single Linux machine, essentially using Kubernetes as an alternative OS.

That's only a problem if you allow untrusted users operate the docker daemon.

source?

Anecdotal, but I know a guy working as a senior Engineer at Google with some central server-side components for the Android ecosystem. He had barely heard the word Kubernetes when we last spoke, let alone knew what it was.

For the record, the Google developers I know also don't use it and generally don't care about it. But it's a big company, I'm sure they have a few users

You can run a single-node cluster. Not the best option and overkill if you don't have the need for redundancy, but it might save you some time deploying software. Honestly at that point you might be better running your software using docker-compose or something like that.

For development, microk8s is actually very nice: https://microk8s.io

Have they solved the high CPU usage problem while it is running (even when no containers are inside)? I don't like my laptop hot, so never could make a switch.
