If you’re looking to get started with Kubernetes this year, there’s a lot of great free resources available for you and I’m going to focus on three excellent ones from VMware. The first is KubeAcademy.
KubeAcademy is a free, product-agnostic Kubernetes and cloud native technology education program built by experts at VMware. The courses are predominately for beginners but also include intermediate and advanced topics in Kubernetes such as building apps and images, networking, and observability:
I recently ran into a problem where new vSphere-hosted virtual machines that are cloned from existing VMs have the same IP address. I assumed the clone process took care of these issues but apparently not. To fix this, I found the following solution:
Remove machine-id with sudo rm -rf /etc/machine-id
Run dbus-uuidgen --ensure=/etc/machine-id
After a reboot, the cloned VM has a new IP address!
In Part 1, we built the hardware build of materials and determined the utilization of a basic VMware Cloud Foundation (VCF) management domain deployment. But we need to put the “cloud” in by adding automation and self-service capabilities provided by vRealize Suite. To accomplish that, we can use SDDC Manager to deploy all the components of the vRealize Suite: Operations, Automation, and Log Insight into the SDDC. In this post, we’ll explore the compute and storage requirements for these components like we did in the previous post. This is going to explore the components required for a single region SDDC. There are a few more steps and components needed for setting up Cross-Region support.
I must admit that I wasn’t on the Kubernetes bandwagon from beginning. However, I’ve seen it mature rapidly over the last 4 years with an expanding ecosystem and high rate of adoption that has given me confidence that there is a future with Kubernetes and now is the time to invest in learning it. Here are the 3 things I observed over the last 12-18 months to solidify that now is the time for me to focus on becoming a Kubernetes expert:
Cloud Native Landscape Explosion
The Cloud Native Computing Foundation (CNCF) began publishing the CNCF Cloud Native Landscape back in 2016 to illustrate the projects and enterprise software that are part of the cloud native ecosystem and community. The Cloud NativeLandscape graphic originally contained three projects: Kubernetes, Prometheus, and Opentracing. Today, it includes over 48 (not including CNCF member/non-member products and projects)! Observing this type of growth signals heavy investment by organizations and individuals to improving core functionality of Kubernetes or filling gaps in the ecosystem.
Today I took my first VMware certification exam in 7 years and happy to report that I successfully passed the Professional vSphere 6.7 Delta Exam 2019(2V0-21.19D) to become a VMware Certified Professional again!
A common question I
receive from customers is why they don’t see a VMware
Cloud Foundation license in the MyVMware portal. What appears instead is
licenses for each individual product that make up the VCF
edition you purchased. Which is typically:
I’ve been at VMware for 12 weeks now and continuing to work towards being a vSAN expert. One of my many challenges facing that goal is not only learning the current state of vSAN’s features and capabilities (the latest being 6.7U3) but also learning how vSAN operated in previous versions to articulate to my customers why feature X in this release is relevant to them.
VMware has released updates to vSAN 75 times since the initial release in 2014 and 12 updates in 2019 alone. So where is the best place to start for having a foundational understanding of modern vSAN functionality?
