Documentation

View the Documentation for the version you are using:

https://spoved.github.io/k8s.cr/

Usage

K8S.cr should support Kubernetes API from 1.11.0 and beyond. In order to use the bindings, you will want to include the VERSION that best maps to your k8s api version. Requiring more than one version at this time will result in an error.

require "k8s/versions/v1.20"

Resources

Some examples on the easier methods to grab/set variables:

# Access a nested path
resource.spec![:template, :metadata, :labels, :app]

# Set a nested path
resource.spec![:template, :metadata, :labels, :app] = "myapp"

# Can use symbols or strings
resource.spec![:template]
resource.spec!["template"]

CRD Generation

To generate resources for a CRD, you can use the crd_gen.cr file.

# First dump the CRDs to a file
kubectl get crds -o yaml > crds.yaml

# Then generate the resources
./lib/k8s/bin/gen_crd.cr -- ./crds.yaml <output directory>
