Hey all! Just wanted to share that I have released an Alpha version of [kube-client](https://github.com/spoved/kube-client.cr) a Crystal client for interacting with the Kubernetes API. This initial release supports the kubernetes api versions 1.11-1.23. Check it out here: **[GitHub - spoved/kube-client.cr: k8s api client](https://github.com/spoved/kube-client.cr)** Report issues here: **[Issues · spoved/kube-client.cr · GitHub](https://github.com/spoved/kube-client.cr/issues)** I hope to continue to develop and improve this client as time goes on. If you are interested please give it a try and report any issues you find. Thanks! ---

What you may also want to consider is creating a `Podman` client/interface. [https://podman.io/](https://podman.io/) Podman is a container engine that’s compatible with the OCI Containers. [https://opencontainers.org/](https://opencontainers.org/) More information on it. [https://docs.podman.io/en/latest/index.html](https://docs.podman.io/en/latest/index.html) Having Crystal apps for these Open Source standards can make it a player in these spaces. ---

Yeah i agree, trying to build tooling as i run into them. Podman is an up and comer now that docker sucks. ---

I had a look at the shard to see what the experience would be like for building operators (my main use case for creating [this Kubernetes client](https://github.com/jgaskins/kubernetes)) and I couldn’t get it to load my CRD. The README mentions these two methods, which seem to be intended for that: - `K8S::Resource.from_file` - `K8S::Resource.from_files` But neither of them exist: ```crystal require "./src/kube-client/v1.23" pp K8S::Resource.from_file("./crd.yaml") # In example.cr:3:18 # 3 | pp K8S::Resource.from_file("./crd.yaml") # ^-------- # Error: undefined method 'from_file' for K8S::Kubernetes::Resource.class ``` I get the same error for both methods. Am I just not doing it right? ---

@jgaskins ah. no your not doing it wrong. its a bug. i didnt make `from_file` a class method. You can just do a `from_yaml` tho. ill fix that up. ---

Pushed a quick release. `0.3.1` it really was a issue in the sub-shard that holds all the k8s classes/structs ([GitHub - spoved/k8s.cr: A Kubernetes lib containing definitions for Crystal-lang](https://github.com/spoved/k8s.cr)).
