Goodbye Etcd, Hello PostgreSQL: Running Kubernetes with an SQL Database
Looking at [1], is there any reason why this couldn’t run in something like DynamoDB? I feel like the operations required would fit

What is going on with Kubernetes Microdistros?
I don't like some of the decisions that k3s makes which is why I stay away from it, but it's a great project. I'm not using kine yet, but I fantasize about using it exclusively every time I deal with etcd-induced slowness/random CPU spikes on my group of controller nodes. k0s supports kine too of course but I just haven't switched it on yet.

Databases = Frameworks for Distributed Systems
Well in some situations you can also get away with CRDTs or Gossip (SWIM), but yeah in the general sense Paxos (Raft is a Paxos-family algo). There are lots of paxos family algos to choose from[0].
> I’m also currently building a distributed search engine using etcd for the service registry, broker peer announcements, and worker queue and it’s been a good experience so far.
As a random stranger on the internet, please build an abstraction layer around etcd. Even if there's only one implementation, I've found that so many distributed projects that just never reach the scale that etcd is built for would benefit from the option of writing their own drivers (you don't need a full plugin system just a regular abstraction layer).
One example is Kine[0] for k8s -- if k8s had a built in option for writing/reading from something like Postgres from the beginning it would have been a better project for it, IMO.
If you do build a plugin system though, you can pass off the work of maintaining the other implementations!

K8s on Pg
I could spent >0s looking into this, but I've been curious how kline implements Etcd's Watch API. For the matter, I don't have much idea in general how kline handles data. Kline would be a great candidate for a blog post or introductory technical article on.
I do quickly see one issue- evidently watches presently use polling. The issue requests use of postgres triggers: https://github.com/k3s-io/kine/issues/20

rqlite 6.0: the evolution of a distributed database design
Not to be mistaken for high-availability Dqlite[1], which is one of the options one can run the k3s kubernetes distribution on (instead of etcd), via the Kine etcd shim[2]. Ultimately though the K3s team replaced Dqlite with an embedded etcd to get high-availability[3].

Installing Kubernetes on mac with vagrant and virtualbox
This is my first attempt to install and use Kubernetes. I am trying to install an environment on Mac for developing my own apps and deploying them for test locally with Kubernetes. I am familiar with using Vagrant, VirtualBox and Docker for the same purpose. When I saw this page https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/vagrant.md I assumed it would be trivial. I executed these lines:

How can I specify persistent volumes when defining a Kubernetes replication controller in Google Cloud?
I see in the docs how do do this for pods, but I want to use a replication controller to manage my pods, ensuring that there is always one up at all times.

Does AWS support Kubernetes?
I've read that AWS does not support Kubernetes and builds their own Docker orchestration engine EC2 Container Service. However, on Kubernetes getting-started -page there is a guide on how to run Kubernetes on AWS: https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/aws.md

What is the recommended way to upgrade a kubernetes cluster as new versions are released?
I heard here it may be https://github.com/kubernetes/kubernetes/blob/master/cluster/kube-push.sh. If that is the case how does kube-push.sh relate to https://github.com/GoogleCloudPlatform/kubernetes/blob/master/cluster/gce/upgrade.sh?

Reading streaming http response with Python "requests" library
I am trying to consume an event stream provided by the Kubernetesapi using the requests module. I have run into what looks like abuffering problem: the requests module seems to lag by one event.

What does edge-based and level-based mean?
I read "In other words, the system's behavior is level-based rather than edge-based" from kubernetes documentation:https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/api-conventions.md

kubernetes pod status always "pending"
I am following the Fedora getting started guide (https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/getting-started-guides/fedora/fedora_ansible_config.md) and trying to run the pod fedoraapache. But kubectl always shows fedoraapache as pending:
