How do I determine which apiGroup
any given resource belongs in?
kind: Role
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
namespace: default
name: thing
rules:
- apiGroups: ["<wtf goes here>"]
resources: ["deployments"]
verbs: ["get", "list"]
resourceNames: []
The named groups are at REST path /apis/$GROUP_NAME/$VERSION and use apiVersion: $GROUP_NAME/$VERSION (for example, apiVersion: batch/v1 ). You can find the full list of supported API groups in Kubernetes API reference.
Kubernetes v1. 25 offers beta support for publishing its APIs as OpenAPI v3; this is a beta feature that is enabled by default.
Use kubectl API-resources: We utilize the 'kubectl API-resources –o wide' command to acquire all the API resources maintained by the Kubernetes cluster. We get name, namespaced, kind, shortnames, and apiversion of the resources by executing the command as mentioned above.
The Groups API is a collection of Graph API endpoints that let you read and create Facebook Group data on behalf of group members.
To get API resources - supported by your Kubernetes cluster:
kubectl api-resources -o wide
example:
NAME SHORTNAMES APIGROUP NAMESPACED KIND VERBS
deployments deploy apps true Deployment [create delete deletecollection get list patch update watch]
deployments deploy extensions true Deployment [create delete deletecollection get list patch update watch]
To get API versions - supported by your Kubernetes cluster:
kubectl api-versions
You can verify f.e. deployment:
kubectl explain deploy
KIND: Deployment
VERSION: extensions/v1beta1
DESCRIPTION:
DEPRECATED - This group version of Deployment is deprecated by
apps/v1beta2/Deployment.
Furthermore you can investigate with api-version:
kubectl explain deploy --api-version apps/v1
Shortly you an specify in you apiGroups like:
apiGroups: ["extensions", "apps"]
You can also configure those settings for your cluster using (for example to test it will work with next 1.16 release) by passing options into --runtime-config
in kube-apiserver.
