Last weekend I decided to play around with my old workstation that’s just been sitting around powered off for years now, mostly replaced by a RaspBerry Pi3 which handles most of my home network and storage. The workstation is from around 2009, isn’t particularly fast but has 6GB of RAM and doesn’t consume much power if you yank the video card. I have a small Rails 4 app running as a backend for one of my Android pet projects, and thought it might be fun to repurpose this machine to host it on OpenShift.…

For my work on OpenShift I wanted a way to use my local workstation as a test cluster with vms for a master and multiple nodes. Ideally it would be possible to quickly teardown and rebuild the whole cluster, but I also want reliable hostnames (and IPs) across each rebuild. This post outlines a way to do this with Fedora (25 as of writing) and Vagrant. The key to getting Fedora configured such that the hostnames and DNS will work is this post by Dominic Cleal.…

I’m currently working on an Ansible role to deploy an application to OpenShift. My application template uses a BuildConfig with a dockerStrategy, so when a build is run it runs against a remote git repo and branch. I wanted my role to ensure that the current deployed application is up to date with the git branch, so we can push changes to that branch and whenever ansible runs it will know to reprocess the template, triggering a new build and deployment.…

I’ve just uploaded a v1.11 release of NetWorth, my personal finance / net worth tracking / budgeting app for Android. This is a pet project, just modelling how I thought and have learned about personal finance and retirement planning. I was hoping to do a grand 2.0 release but as ever time evaporates and I couldn’t quite get there yet. However I did manage to find some time for a lot of nice improvements and figured it was worth pushing them out until I get working on it again.…

On my personal VPS I host a handful of websites accessed from a variety of domains and sub-domains, as well as a few more involved webapps such as tt-rss. Historically applications that cross multiple programming languages and databases have been a terrible pain to deploy and keep running on a private server, but since containers have arrived this has become a lot easier. On my server, I wanted to have a web server listening on the standard http/https ports proxying traffic for a variety of sites and applications, based on the domain/sub-domain in the request.…

A large portion of my time on the OpenShift team has been spent working on cluster lifecycle improvements, particularly in the realm of upgrades. Throughout this work we’ve been targeting the ability to upgrade clusters without requiring application downtime. I recently took some time to demonstrate that we can hit that target, please check out the results on the OpenShift Blog: Zero Downtime Upgrades With OpenShift Ansible…

With Kubernetes 1.4 sig-cluster-lifecycle released an alpha of kubeadm, a new utility we’ve been working on to make cluster bootstrapping as simple as possible for new users, but also provide tooling and infrastructure that can be used for production clusters. The initial goal was simple, install the bits (now delivered via new OS packages), one command to create a cluster: $ kubeadm init And one very short command to copy and paste to join nodes to the cluster:…
