GitOps is the best way to operate and execute workloads in Kubernetes clusters. In fact, using a Gitlab repository and some files, it’s possible to build a declarative deployment system able to create and manage namespaces, policies, service accounts, limits…, and the workload rollout. Based on my personal and working experience, I’d like to share in […]
Finally, I got a couple of hours to upgrade my lab from vSphere 6.7 to vSphere 7. Following one of the announcements during VMworld 2019, this new release comes with some great functionalities like the native support of Kubernetes, the dynamic hardware assignment, and some enhancements on DRS, vMotion, etc… For my lab purpose, I’m […]
As seen in my previous post, the “for-each” statement can be used by Terraform main and data to cycle on VM properties and properly fill the cloud-init templates transforming a single static declarative file, into a dynamic template that could be reused in a lot of cases. During the Terraform execution probably you’ll see that […]
I already write here about the ability to use Cloud-init in conjunction with Terraform to build an efficient and infrastructure-as-code system to cover infrastructure and configuration setup using the same deploy engine. Now. it’s time to take a step forward, showing how to use a for-each statement with Terraform to deploy different virtual machines using […]
Cloud-init is an interesting industry solution for the distribution of computational resources across the major cloud providers (private included). Starting from an empty template, it’s possible to attach and apply every OS configuration, without manual intervention. In this way, IP addresses, users, packages and etc, are applied without user interaction. IMHO this is a key […]
With the coming of Cloud-Native Applications, the need to handle, scale and integrate containers instead or with the traditional applications, is bringing a lot of IT professionals to be more and more involved in the Kubernetes world. In fact, this new model to deliver workloads has different roles and approaches compared to the traditional virtual […]
Cloudflare, one of the most important security platform in the world, is an interesting solution for surely publish and maintain contents over the internet. The ability to handle DNS acts as a reverse proxy and take care of the incoming connection from the Internet to my own server are the main reasons why I choose […]
As promised on my post here, it’s time to show how dive into vSphere scenarios generating the “infrastructure as code”. In fact, the modern cloud infrastructures are more and more delivering the final customer using many automation tools like Terraform. In this way, it is possible to consume cloud resources regardless of the underline cloud […]
My previous lab described here was composed by a SuperMicro E200-8D equipped with an Intel Xeon D-1528, 32GB RAM, and a single 512GB SSD. During my labs, I noticed how the vCenter is able to consume a lot of resources even if deployed in the smallest available configuration. Near this problem, the new need is to have two […]
How many infrastructure administrators are repeating the same task many times? Unfortunately, it happens again and human mistakes are in the nearest corner! PowerCLI is giving a great hand that really contribute to stopping “monkey works” on vSphere based infrastructure and solve a lot of infrastructure automation tasks like deploy and manage, migrations, making detailed […]
