Prepare for Deploying an Application to Kubernetes
December 1, 2022
Flux uses GitOps principles to deploy applications to Kubernetes. Main benefits of this are:All k8s configuration yaml files are version controlled. We know exactly what changes were applied and when.Very few admin users will need access to the k8s cluster. All changes happen via pushing config files to a Git repo. This makes the cluster more secure.
Before we can deploy our application, we will do a few prerequisite work.Part 1 R
Introduction to GitOps

What is Jenkins Templating Engine(JTE)?
February 25, 2020
1.1 Why JTE?
Modern Jenkins use consists of defining and using pipelines. Pipelines define and control a specific set of operations in the CI/CD process. These operations call out specific tools and directories. Pipelines are not reusable across projects. JTE uses more generic templates that may be reused across projects. Traditional pipelines are not reusable because they are hard coded.1.2 What is JTE
JTE allows the definition of pipeline templates.&nb

Are you a developer looking to shift your career to a DevOps model? Maybe you’re a fully trained Ops person who wants to know what DevOps is all about. Or maybe you’re neither. Whatever the case may be, if you’re interested in learning DevOps, there’s a couple things you should know. The first: DevOps is not a role.

Configuration Management – Just Do It!
March 29, 2017
Configuration Management, as applied in DevOps, is the practice of using tools to manage the configuration of our technical architecture. Put simply, we document the desired state of one or more servers in a machine-readable form, and then use a configuration management tool (e.g. Chef, Puppet, Salt, or Ansible) to setup the real items to match the configuration.
Why? As with many things, you might think “I barely have time to setup this server manually, never mind write a script for it
