Dissecting a Kubernetes manifest thumbnail
Kubernetes manifests can seem quite daunting at first, but it is important to understand that their apparent complexity is simply a result of the large number of customization options. In the end, manifests are used to deploy resources that interact with each other, which, among others, lead to the correct operations of containerized applications. Consequently, resources specified in a manifest must be configured accordingly. This article aims at explaining how manifests are structured to do so.
