Sort of. Kubernetes is lowest common denominator by design. Specific ecosystems had much more efficient solutions to these problems (e.g. rather than having to deploy a whole docker container to do a version upgrade you deploy just your specific web application) but the problem was those solutions only worked for those specific ecosystems.
- hosh 2y agoI disagree. Kubernetes is composed from primitives that can be applied in versatile ways. Those primitives can be swapped out for even greater extensibility. Kubernetes is not the lowest common denominator, and more of a toolkit that can broadly and deeply applied to many setups. Templated yaml or json is a step backwards. Those are not composable. If we wanted something like that, then we would need to at least be able to do merges and transforms. Something like jquery or css for yaml that allows to transform fields based upon selectors. Manifest generators using a real language, on the other hand, start with data structures that can be merged and transformed before its final output as yaml. They can take advantage of language features. The one I wrote in Ruby can take advantage of class inheritance and mixins, allowing me to define common configs across resources. Someone who can distill the algebra of merging Kubernetes manifests can do that for a functional programming language.
