Some time ago I wrote a post entitled ‘Kubernetes networking 101‘. Looking at the published date I see that I wrote that more than 2 years ago! That being said – I think it deserves a refresher. The time around, Im going to split the topic into smaller posts in the hopes that I can more easily maintain them as things change. In today’s post we’re going to cover how networking works for Kubernetes pods. So let’s dive right in!
In my last post – I described a means in which you can quickly deploy a small Kubernetes cluster using Ansible. I’ll be using that environment for all of the examples shown in these posts. To refresh our memory – let’s take another quick look at the topology…
The lab consists of 5 hosts with ubuntu-1 acting as the Kubernetes master and the remaining nodes acting as Kubernetes minions (often called nodes now but I cant break the habit). At the end of our last post we had what looked like a working Kubernetes cluster and had deployed our first service and pods to it. Prior to deploying to the cluster we had to add some routing in the form Continue reading

I’d like to share with you an article based on my talk at Tarantool Meetup(the video is in Russian, though). It’s a short story of why Mamba, one of the biggest dating websites in the world and the largest one in Russia, started using Tarantool. Why did we decide to busy ourselves with MySQL-to-Tarantool replication?
First, we had to migrate to MySQL 5.7 at some point, but this version didn’t have HandlerSocket that was being actively used on our MySQL 5.6 servers. We even contacted the Percona team — and they confirmed MySQL 5.6 is the last version to have HandlerSocket.
Second, we gave Tarantool a try and were pleased with its performance. We compared it against Memcached as a key-value store and saw the speed double from 0.6 ms to 0.3 ms on the same hardware. In relative terms, Tarantool’s twice as fast as Memcached. In absolute terms, it’s not that cool, but still impressive.
Third, we wanted to keep the whole existing architecture. There’s a MySQL master server and its slaves — we didn’t want to change anything in this structure. Can MySQL 5.6 slaves with HandlerSocket be replaced Continue reading
