would be entwined for a significant time after that podcast. Fast forward to August 2019, and I was making an internal move at Red Hat from the Ansible team to the OpenShift (Red Hat’s Kubernetes product) autohealing because containers are fungible and immutable. A container can be restarted or scaled at will, making it easy to manage workloads in this model. It is important to grasp these Kubernetes concepts because minimize this grunt work and help you avoid duplicating manifests. Kustomize Kustomize is a framework for patching–or selectively altering–files, built into Kuber- netes. It is a configuation manager

collaborate on a codebase to move it forward. Instead of a single developer who owns the codebase making all the decisions, a group of developers works together to make a product. In this situation, of the way, leaving the developer in a flow state. DX allows developers to be more effective, by making the good thing the easy thing – in areas such as testing, security and observability this is increasingly platform approach brings. Benefits of the platform approach Platforms are exceptionally good at making components repeatable and reusable. This trait is especially useful when an application needs to

Getting visibility repository and takes care of the actual deployment by pulling changes in your cluster (and thus making the cluster state the same as the Git state). This scenario is great in theory and is certainly what is going on in each environment and can quickly lead to configuration duplication or people making commits to specific environments (instead of using shared configuration). For example, if

Increased Consistency and Standardization Because GitOps provides one model for making infrastructure, apps and add on changes, you have consistent end to end workflows across your entire kubernetes-cni Part 1: Spin up a Kubernetes Cluster eBook 17 4.
