Kubernetes

This extension support k8s:// url, include secret and configmap resource

pip install pykebab[k8s]

k8s://<namespace>/<resource_type>/<resource_name>[/<data_key>]

namespace: if . map to default namespace in a word, the two below is equivalent

k8s://default/secret/default-token-rm42d
k8s://./secret/default-token-rm42d

resource_type: either secret or configmap/cm, cm is an alias of configmap the two below is equivalent

k8s://kube-public/configmap/cluster-info/kubeconfig
k8s://kube-public/cm/cluster-info/kubeconfig

kubectl get -n kube-public secret default-token-z9z4w -ojsonpath="{.data.namespace}"

gives an base64 encoded a3ViZS1wdWJsaWM=, when decoded, it is kube-public

we promote that out of other metadata, and decode it if it is secret, so you can reference to the value directly

kebab k8s://kube-public/secret/default-token-z9z4w/namespace

call the above will give you the namespace

"kube-public"

Note that all the default-token-xxxxx, the xxxxx part is dynamic for every cluster.

This extension support s3:// url
