Use the attached checklist to create or validate a robust and reliable Kubernetes Production setup for running critical applications. Kubernetes has gained much traction and is now the standard orchestration layer for containerized workloads. CI/CD Toolchain for DevOps. In this reference architecture, we’ll build a baseline infrastructure that deploys an Azure Kubernetes Service (AKS) cluster. Anita has over 20 years experience in software development. The all-in-one setup is easy to start with, and comes with an executable bundle to launch. Instead, we set up these clusters manually on different hosts, with all the tuning necessary to optimize the data store in question. Kubernetes Networking Options ¶ Introduction ¶. Deploying Kubernetes in the production environment is not an easy task. One or more machines running a deb/rpm-compatible Linux OS; for example: Ubuntu or CentOS. Every organization using Kubernetes (or wanting to use Kubernetes) must… Installing Kubernetes — There are many ways to install Kubernetes Guide and the obvious starting point is the setup section, but the installation process can sometimes be a challenge.
