Ingress Resources, the final piece of the puzzle?

Development Kubernetes Docker

I’ve been using service-loadbalancer in my cluster and annotated my services to make them available outside the cluster network. With the release of Kubernetes 1.2 there is another alternative, the Ingress Resources.

You can read more about the Ingress resource in the Kubernetes Reference Documentation.

Storage for your cluster

Development Kubernetes Docker Storage

I’ve been working on getting Elasticsearch working on Kubernetes-On-ARM. The biggest problem has been storage. I’m using Elasticserach for storing logs and the cluster generates 1.4 million entries per day (i know, need to do something about it).

If you want to deploy your applications to Kubernetes, sooner or later you need to think about how to solve storage and persistence.

E(F)K cluster on Kubernetes-On-ARM - Part 2

Development Kubernetes Docker ARM Raspberry PI

This is the second part in a series about handling logs on Kubernetes-On-ARM. In the first part we installed ELK and started sending syslog events from our nodes using logstash-forwarder. In this part we will start collecting logs from our pods and Kubernetes components. If you wan’t to cache up here’s a list of previous posts:

• Kubernetes-On-ARM
• ELK cluster on Kubernetes-On-ARM - Part 1

The plan was that this part would be about how to start collecting logs from Kubernetes. But I wasn’t satisfied with how logstash-forwarder worked. The thing is that, once the logstash-forwarder daemon is started, the node can’t run much else.
