• I still haven’t been blogging
    Last year at around this time I wrote a post about how I hadn’t been writing posts lately, and how I wondered whether it made sense to re-up my wordpress.com subscription, and how I went ahead and re-upped it anyway. I went on to talk about a few of the things I might blog about, … Continue reading "I still haven’t been blogging"
  • Long Time No Blog
    My annual resubscription to this wordpress.com instance has come and gone again, and, as in the previous few years, I thought: “Should I renew? “Well, you still want to have a blog, even if you don’t, uh, write blog posts.” “But what about how I always get annoyed with wordpress, and always want to Blog … Continue reading "Long Time No Blog"
  • More Fun with Kubeadm & Fedora
    I recently wrote about getting up and running with kubeadm and Fedora CoreOS, which I got working, but which sent me into a miniature funk of uncertainly over various little integration issues. First, I was getting around the lack of support in rpm-ostree for rpms that place stuff in /opt, which isn’t a traditional place for … Continue reading "More Fun with Kubeadm & Fedora"
  • Installing Kubeadm on Fedora CoreOS
    There are many different ways to bring up a Kubernetes cluster, but the simplest option I’ve found for getting up and running with a single or multi-node cluster involves a tool called kubeadm, for which the Kubernetes project maintains good installation and configuration docs. These docs include directions for hosts running Debian/Ubuntu, RHEL/CentOS and Container … Continue reading "Installing Kubeadm on Fedora CoreOS"
  • Install Docker CE on Fedora Atomic Host (if that’s what you’re into)
    Fedora Atomic Host comes bundled with a version of Docker based on this project atomic repo that moves no faster than the upstream Kubernetes project can abide (currently docker-1.13.1). This means that Fedora Atomic pretty much always ships with an older version of docker than what’s available from Docker Inc. However, through the magic of … Continue reading "Install Docker CE on Fedora Atomic Host (if that’s what you’re into)"
  • Trying Out a New Path to Kubernetes: Kubespray
    I just came across this Little Guide to Kubernetes Install Options, which covers a few options I’ve heard of, and a few options I haven’t heard of. It doesn’t mention the main way that I deploy Kubernetes, which is through the Ansible scripts from the kubernetes/contrib repository. The post does point to another Ansible-based option, … Continue reading "Trying Out a New Path to Kubernetes: Kubespray"
  • Recent Adventures in oVirt and Gluster
    At the end of last week, I spied an exciting tweet about oVirt: Not long after I started using oVirt and Gluster together, the projects started talking about a way to improve Gluster performance by enabling virtualization hosts to access Gluster volumes directly, using Gluster’s libgfapi, rather than through a FUSE-mounted location on the virtualization … Continue reading "Recent Adventures in oVirt and Gluster"
  • testing system-containerized kube and friends
    A month or so ago I jotted down some notes on using ansible to set up a kubernetes cluster on atomic hosts with kubernetes running in regular docker containers and flannel and etcd running in system containers. I’ve been working on turning my kube containers into system containers. Three reasons jump to mind: I want … Continue reading "testing system-containerized kube and friends"
  • getting stuff done with a local openshift origin instance
    A few of the projects I work with use static websites based on middleman, which you can run locally to see how your edits, or those of others, will look on the live site when they’re merged. Each of these sites defaults to port 4567 when running locally, so if I’m running more than one … Continue reading "getting stuff done with a local openshift origin instance"
  • test containerized kube and system container-based flannel and etcd
    This will fail (if you use hostnames) at: TASK [flannel : Load the flannel config file into etcd] because we need this PR in the Fedora etcd system container. You can work around by sshing into your master, and editing the resolv.conf inside of your etcd system container to match the host, exiting, and re-running … Continue reading "test containerized kube and system container-based flannel and etcd"
