    Handoff to Day-N Automation with vSphere Content Libraries and Netbox

    The challenge with build automation is too much convenience Think about it. If it's easy to compose and deploy workloads, it's also easy to develop sprawl, and a good system designer would have methods in place to mitigate that. In a previous post I covered how to deploy vSphere VMs with Ansible and the Automation …

    Why wait? Eventual Consistency and Reliability

    Patience is tough when deploying automated code; Here's why it is important Reliability-centric infrastructure engineers need to focus on careful, procedural, validated workflows; the systems we're responsible are simply too important to casually "toss" infrastructure requests at a common API gateway. We …

    Ansible is a fantastic tool for Linux-based and NOS-based automation. Have you seen this error before? 1"changed": false, "msg": "Failed to connect to the host via ssh: Host key verification failed." When you use Ansible with SSH transport (as opposed to an API), you rely on the SSH key trust …

    Deploy vSphere VMs with Ansible!

    In a previous post, we covered how to create a virtual machine from a VM template in vSphere using Python and the REST API as an example of service-agnostic methods to invoke infrastructure resources. VMware's PowerCLI is a fantastic tool, but it's not for me. Tweaking or porting functionality from PowerCLI to other …

    Why Automate? VM Deployment with vSphere's REST API

    VMware introduced RESTful APIs with their vSphere 7.0 release train; migrating from the old MOB APIs is a welcome choice. REST clients provide a powerful tool for automating processes, but it's important to embody reliable practices when interacting with infrastructure. The neat thing about published and documented …

    CI/CD tools aren't just for automatically deploying apps! Jenkins excels at enabling an engineer to automatically execute and test code - but, it has a hidden super-power: Automating boring and intensive IT tasks(removing toil). Let's take a common and relatable IT problem - it doesn't matter if you're a DevOps …

    Rapidly deploying Linux servers to meet a whim represents the essence of home lab activities, but we spend a great deal of time spinning/configuring machines to meet our specs. Worse, we lose a great deal of time keeping them properly configured and up to date, and none have the privilege of unlimited lab time. Let's …

    There are numerous advantages to deploying an internal root CA to an enterprise: Autonomy: Enterprises can control how their certificates are issued, structured, and revoked independently of a third party. Slow or fast replacement cycles are permissible if you control the infrastructure, letting you customize the CA to …

    It's probably safe to say that service provider networking is pretty unique. One particular design pattern - Looking Glasses - is extremely useful for complex dynamically routed networks. I'd really like to shift the gatekeeping needle here - networks that are complex enough to benefit from a looking glass should move …
