Getting started with Velero 1.0.0-rc.1

Last week, the Velero team announced the availability of release candidate (RC) version 1.0.0. I was eager to get my hands on it and try it out. Since it is RC (and not GA), I thought I would just deploy a fresh environment for testing.  The guidance from the Velero team is to test it out in your non-critical environments! On a number of Velero github sites, the links to download the binaries do not appear to be working, plus some of the install guidance is a little sparse. Anyhow, after some trial and error, I decided it might be…

Portworx, STORK and container volume snapshots

As I continue on my cloud native storage journey, I found myself looking at Portworx. The reason for this was down to the fact that Portworx provide a plugin for the Heptio Velero product, and I was interested to see how this behaved on top of my vSphere on-premises infrastructure. I’ve written about Velero a few times already, and done a few posts where I leveraged the Restic plugin for snapshot functionality. Thus, I wanted to see how Portworx achieved the same thing, and wanted to learn about bit more about STORK, Portworx’s Storage Orchestrator for Kubernetes. I’ve written about…

PKS and NSX-T: Error: Timed out pinging after 600 seconds

I’m still playing with PKS 1.3 and NSX-T 2.3.1 in my lab. One issue that I kept encountering was that when on deploying my Kubernetes cluster, my master and worker nodes kept failing with a “timed out” trying to do a ping. A bosh task command showed the errors, as shown here. cormac@pks-cli:~$ bosh task Using environment ‘192.50.0.140’ as client ‘ops_manager’ Task 845 Task 845 | 16:56:36 | Preparing deployment: Preparing deployment Task 845 | 16:56:37 | Warning: DNS address not available for the link provider instance: pivotal-container-service/0c23ed00-d40a-4bfe-abee-1c Task 845 | 16:56:37 | Warning: DNS address not available for the…

Reviewing PKS logs and status

After a bit of a sabbatical, I am back to looking PKS (Pivotal Container Service) again. I wanted to look at the new version 1.3, but I had to do a bit of work on my environment to allow me to do this. Primarily, I needed to upgrade my NSX-T environment from version 2.1 to 2.3. I followed this blog post from vmtechie which provides a useful step-by-step guide. Kudos to our VMware NSX-T team as the upgrade worked without a hitch. My next step was to start work on the PKS deployment. I just did a brand new deployment…

Kubernetes, Hadoop, Persistent Volumes and vSAN

At VMworld 2018, one of the sessions I presented on was running Kubernetes on vSphere, and specifically using vSAN for persistent storage. In that presentation (which you can find here), I used Hadoop as a specific example, primarily because there are a number of moving parts to Hadoop. For example, there is the concept of Namenode and a Datanode. Put simply, a Namenode provides the lookup for blocks, whereas Datanodes store the actual blocks of data. Namenodes can be configured in a HA pair with a standby Namenode, but this requires a lot more configuration and resources, and introduces additional…

Fun with PKS, K8s, VCP, StatefulSets and Couchbase

After just deploying the newest version of Pivotal Container Services (PKS) and rolling out my first Kubernetes cluster (read all about it here), I wanted to try to do something a bit more interesting than just create another persistent volume claim to test out our vSphere Cloud Provider since I had done this  a number of times already. Thanks to some of the work I have been doing with our cloud native team, I was introduced to StatefulSets. That peaked my interest a little, as I had not come across them before.

See you at VMworld 2018

Yes, it’s that time of year again. VMworld 2018 in Las Vegas is taking place next month. Once again, as per previous years, I will be co-presenting on a few sessions. It will be no surprise that, once again, my sessions are focused on storage, hyper-convergence and predominantly vSAN. However, this year I will also be presenting with my CTO and VMware Fellow, Christos Karamanolis, for the very first time. Without further ado, let me go through my sessions in a bit more details, and if they look interesting to you, feel free to sign up. I also included a…
